The Basics of Dilution Chemistry

The Basics of Dilution ChemistryWhen considering how to study for a degree in chemistry, one option is to think about how to become an expert in the chemical world through Dilution Chemistry. This type of chemistry uses the composition of matter to study different molecular configurations of molecules.Dilution Chemistry is using to determine the properties of elements and compounds in the laboratory. Chemists use this method to discover how elements work together, and how substances react in the environment. It is important to note that the concentration of an element in solution does not always equal the concentration in air, and this method is used by chemists to determine this. The concentration of elements is based on the molecular weight of the substance.Since molecules can be of different sizes, dilution is used to discover how molecules interact with other molecules, and how complex chemical reactions happen in the laboratory. For example, you can use this method to determine whether solvents will mix well with certain substances, or how acid, bases, or bases will react with one another. It also helps to find the molecules that are similar to one another, and which react differently.The particles in solution that react and the chemicals that are produced from the reaction determine how the chemical reaction occurs. A lot of different molecules react in the laboratory to form different chemical compounds. One molecule may not even exist without the others, so Dilution Chemistry can be used to explore the interactions between molecules and to determine what is forming in the lab.Because solids are not always found in solution, many molecules are needed to form solid forms, and one will need to determine how these molecules interact with each other in the laboratory. Soil is found in the laboratory because scientists want to find out how soil reacts to different temperatures, and how this soil reacts to heavy metals, or to various chemicals.The chemistry th at is used in this type of experiment includes compound molecules and solids, but it also includes gases and liquids. The atoms of the compounds that combine with solids or compounds in the laboratory will end up in the air or the water when they are broken down into smaller pieces.Like dry chemistry, this type of chemistry can be quite complex and involve many different things. Chemical reactions are created as molecules combine with each other and with solids, and the molecules that react are separated from the rest of the experiment by making a solution.

Area of a Pyramid - Online Tutoring

Area of a Pyramid - Online Tutoring Pyramid is a geometric figure formed by a polygon base joined to a point.This point is called as the apex. Theedges of the base and the apex form a triangle. Area of the pyramid when all the side faces are the same isB+ 1/2PL. Here B is the base area of the pyramid, P is the perimeter of the base and L is the slant height. Example 1: What is the area of the pyramid which has a rectangular base with dimensions 4 cm, 8cm and slant height 6 cm? The rectangular base dimensions are 4 cm and 8 cm respectively. The base area = 4 cm * 8 cm = 32 cm2. The base perimeter = 2(8 + 4) = 2 * 12 = 24 cm. Slant height = 6 cm. Area of the pyramid = B+ 1/2PL Hence, Area = 32 + 1/2(24 * 6) = 104 cm2. Area of the pyramid = 104 cm2. Example 2: What is the area of the pyramid which has a rectangular base with dimensions 3 cm, 6 cm and slant height 10 cm? The rectangular base dimensions are 3 cm and 6 cm respectively. The base area = 3 cm * 6 cm = 18 cm2. The base perimeter = 2(3 + 6) = 2 * 9 = 18 cm. Slant height, L = 10 cm. Area of the pyramid = B+ 1/2PL Hence, area = 18 + 1/2(18 * 10) = 108 cm2. Area of the pyramid = 108 cm2.

Is the SAT Essay Required

Is the SAT Essay Required Typically, a portion of SAT prep time is dedicated to success on the essay section. As of late, however, a large number of schools are making the SAT essay optional to applicants. Ivy League schools including Brown, Harvard, and Yale are no longer requiring students to sit for the essay section of the exam. This begs the question, what does this mean for you?

SAT essay basics The SATs essay is a 50-minute assessment in which youre asked to read a passage and to then write an essay that explains how the author forms his or her persuasive argument. A successful SAT essay will point to evidence from the passage as support for its explanation. The essay is scored on the following criteria: Readinghow well you understood the passage and its central ideas. Analysisyour ability to give insightful analysis of the passage and to evaluate the authors use of evidence and reasoning. Writingyour essay is well organized and shows a good command of standard writing conventions and style. [RELATED: What is an Average SAT Score?] Changes to the SAT essay In 2016, the SAT changed its essay portion from required to optional. This began raising the question for students and colleges alike as to whether to continue using the essay for admissions. Now that the essay is optional for test-takers, many schools are changing their application requirements, as well. In the first eight months of 2018, a slew of prominent schools, including Harvard, Dartmouth, and Yale, announced that they would no longer require the SAT essay. The end result is that only a handful of schools nationwide require the essay, although others still recommend that students take it. There are several reasons schools give for dropping the essay requirement. One primary reason is that many public school students are now able to take the SAT for free during the school day, and those tests dont always include the optional essay, which costs an additional amount. Also, colleges and universities generally already require applicants to show their writing ability in other ways, making the essay test less essential to some admissions processes. [RELATED: ACT and SAT Test Dates for 2018-2019] Who should take the SAT essay? Although the essay is now optional for test-takers and most colleges are no longer requiring it, that doesnt mean you shouldnt consider taking it. First, find out whether any of the schools youre interested in require or recommend the essay. You can find this information here. If your schools of interest require you to submit an essay score, be sure to sit for it on test day. Additionally, if the schools youre interested in dont require the SAT essay, it could still be a good way to showcase your writing skills to these schools. If you choose not to take the essay, inquire about other ways you can show your writing skills to these potential schools. Regardless of whether a school requires or recommends the SAT essay, they still view writing as an important skill for college success. Typically, schools will require their own essays as part of the overall application process, and some are asking students to submit a graded high school essay as an example of their writing skills. Use those opportunities, as well as the SAT essay if you so choose, to showcase your style and analytical abilities, and make the case that youre a worthy applicant.

17 Tips For Recording Acoustic Guitar At Your Home Studio

17 Tips For Recording Acoustic Guitar At Your Home Studio Suzy S. Curious about recording acoustic guitar tracks at your home studio? Check out these helpful tips for before and during the session from Perth Amboy, NJ teacher  Jeff S... If youve tried recording acoustic guitar before, theres a good chance you know how demoralizing it can be to think youve captured a wonderful performance, only to learn later that its sonically flawed. Id like to offer some tips, with hopes they will assist you in rendering consistently clean and clear acoustic guitar tracks. Before you even begin, here are some tips for setting up: Find the place in the room that you feel your acoustic guitar or voice sounds best, make a mark on the floor, and also take detailed notes. Include the height of the mic off the ground, the distance between you and the mic, and the angle of yourself and the guitar in relation to the mic. Better yet, have someone take a picture of you recording in your “sweet spot.” Spend some time choosing and verifying the tempo at which you’re going to record the song. Experiment with a few different tempos until you find just the right one. Determine the mood of the song  you are recording and base all your decisions around that. Is the guitar meant to be gentle? Aggressive? Graceful? Attacky? Both the guitar part and the vocal approach will fly or die by your accurate assessment of the mood! Record acoustic guitar and vocals in mono, as these are monophonic sources. Once you get a beginning-to-end performance of the main guitar part, you can think about recording it again and either using the second part to beef up the sound or run one guitar track on the left channel and one on the right. Some engineers like to record with two different mics simultaneously, pointing one at one part of the guitar and one at another part of the guitar. Experiment and see what floats your boat. Record both guitar and vocal without any reverb, effects, or EQ adjustments. Add what you wish after it, but cut the tracks dry. This gives you much more flexibility when you mix. Set your volume levels so that you don’t end up pushing the meter into the red more than once or twice per track (even that might cause distortion enough to ruin an otherwise good track) and then focus on maintaining that level and waveform size as you replay or re-sing the part. Count in one or two measures before you start recording the guitar part. Don’t have the volume of the click track up so high that it bleeds through the headphones into the microphone. Its prudent to record with a click track, but you need to make sure its not so loud that the clicks get picked up in your vocal or instrument mic. Consider extra purchases. If your recording room isnt soundproofed and you dont have the time or the budget to make it so, dont worry. There are several effective and reasonably priced options that will quell the bleed-throughs. Three you might consider are sE Electronics Reflexion Filter X Portable Vocal Booth (just under $125), sE Electronics Reflexion Filter Pro model (just under $250), or the Auralex Pro Max (just under $350).  You might also want to consider getting a wind screen. Next, heres a list of some of the most important tips to keep in mind during your session: Be cognizant of noises, including your own breathing, arm, and hand noises as you move them on the guitar, and other noises that could come from the chair you’re sitting on, the floor, and so on. These will all contaminate your tracks. Nothing is more agonizing than thinking that your performance and recording were pristine, only to later discover that your stomach rumbled or the chair creaked. After you record a track or two, listen to the guitar track for squeaks. Some guitarists hands and styles lend themselves to more squeaking than others. Squeaks are hard to avoid altogether, but aside from being aware of them, you can get coated strings that help reduce squeaking. If youre generally pleased with a performance you record, but it has a few squeaks, write down the times where they occur and then decide whether you’re going to punch in replacement sections or look for a squeakless performance of the section in another part of the song (that you can cut and paste into the squeaky area). Remember to re-tune your guitar (and all other instruments) often during the recording process. As soon as you think you have recorded an acceptable main acoustic guitar part, throw down a quick reference (scratch) vocal (one or two takesâ€"don’t finesse the performance) to see if the vocals work well with the guitar part. In evaluating their synergy, make sure the guitar is not “stepping” on the vocal (i.e. interfering or drawing attention away from) and that there arent any glaring rhythmic or chordal anomalies. Sometimes when you separate the guitar and vocal parts and record them independently, you might alter how you play the guitar part, which makes for a stilted performance. Also, listen to make sure you are not holding out chords or notes too long (or not long enough). If your digital audio workstation (DAW) doesnt automatically save your recordings as they evolve, then you need to remember to click the save button early and often. If applicable, let the final chord of the song ring out until you can’t hear it anymore. And be ever so quiet as it does. Be sure not to breathe loud or move your hands or body. If the song has a fade-out ending, play the fade at least 15 seconds longer than you think you need. Before you decide to end your recording session, listen to the track all the way through. Its easy to lose perspective when you are doing both the engineering and recording. Take notes as to possible EQ modifications you need to make, possible spots you need to punch in, and times and specifics about any performance or recording anomalies that you hear. This way you have a game plan of things to tackle when you return to the project. As you can see, there are a lot of important details to keep in mind when recording acoustic guitar on your own.  But along with those concerns and oversight measures comes an enpowering experience with lots of advantages.  Those include the freedom of recording any day and time youd like without a reservation, deposit, or committing to a minimum block of hours; the ability to leisurely listen and evaluate the quality of various takes;  experimenting as much as youd like with  altering the position of equipment and recording environment without oversight or added expense; using and comparing different types of mics and guitars, etc. So take your time, enjoy the experience, remember to have fun, and pat yourself on the back every once in a while.

GCSE poem analysis Kamikaze by Beatrice Garland

GCSE poem analysis Kamikaze by Beatrice Garland What is it about? The poem tells the story of a Japanese kamikaze pilot who failed to carry out his suicide mission and instead returned home in dishonour. The poem includes the perspective of his daughter, imagining how she told the story in turn to her own children. Kamikaze by Beatrice Garland Her father embarked at sunrise with a flask of water, a samurai sword in the cockpit, a shaven head full of powerful incantations and enough fuel for a one-way journey into history but half way there, she thought, recounting it later to her children, he must have looked far down at the little fishing boats strung out like bunting on a green-blue translucent sea and beneath them, arcing in swathes like a huge flag waved first one way then the other in a figure of eight, the dark shoals of fishes flashing silver as their bellies swivelled towards the sun and remembered how he and his brothers waiting on the shore built cairns of pearl-grey pebbles to see whose withstood longest the turbulent inrush of breakers bringing their father’s boat safe â€" yes, grandfather’s boat â€" safe to the shore, salt-sodden, awash with cloud-marked mackerel, black crabs, feathery prawns, the loose silver of whitebait and once a tuna, the dark prince, muscular, dangerous. And though he came back my mother never spoke again in his presence, nor did she meet his eyes and the neighbours too, they treated him as though he no longer existed, only we children still chattered and laughed till gradually we too learned to be silent, to live as though he had never returned, that this was no longer the father we loved. And sometimes, she said, he must have wondered which had been the better way to die. Form The poem has seven stanzas of six lines each, with an irregular, unrhymed rhythm. This freedom of form suits the poem as a drifting reminiscene that shifts its focus from one character to another and moves through time. The shape of the poem is then simply created by the writer's choice to tell or to stop telling details of the events and feelings. The second and third sentences both begin with 'And', helping this sense of a story verbally retold. Choice and consequence The pilot's choice not to spend his life by attacking his enemy may have saved lives, but he seems to have made new and more personal enemies out of his wife and family: 'they treated him | as though he no longer existed'. In fact if the poem didn't include the shift of perspective and time at the second sentence, we might not know that the pilot returned from his 'one-way' mission. This means that there is an air of mystery about his reasons: his daughter imagines why he may have turned around, but in truth his family simply do not know. On top of this, the fact that they never spoke about it means that she did not even know whether he regretted his choice to return. In fact, the daughter is sure that 'he must have wondered | which had been the better way to die.' Structure Kamikaze is made of only three sentences: notice the full stops after the description of the tuna ('the dark prince, muscular, dangerous.') and the two in the final lines. This gives the first part of the poem - the first five stanzas - a flowing unstoppability, like the train of thought that takes the character of the pilot from the fishing boats to the sea, to the fish and on to his memories. There is something inevitable and unstoppable about his choice for life instead of death. The poem begins as told about a woman ('her') and her family, but the poet uses italic font to mark when the poetry becomes the woman's own words. We can tell because of the shift of pronouns to include 'my mother' and 'we children'. As we saw earlier, this shift of perspective is effective in putting his behaviour in context and actually explaining his return. Imagery Beatrice Garland describes the fishes beneath the boats as 'a huge flag waved first one way | then the other in a figure of eight'. She turns the individual fish into a collective - a shoal - just as the individual can become lost in society, particularly in a society with very rigid codes or in wartime. The 'flag' that the pilot imagines in the water mocks the flags of nations at war: the fish are simply waving their flag for the joy of movement. In fact, this massive flag is much more significant, viewed from the air, than the tiny flags of the 'bunting' of the fishing boats. The poet also uses the senses to give a sense of immediacy and reality to her writing. She references the colours of the 'green-blue translucent sea', the 'pearl-grey pebbles', the 'silver fish' and so on, as well as describing the shapes of the shoals, the cairns and the boats. She references the 'salt-sodden' texture- or perhaps taste or smell - of the grandfather's boat. Memory The poem is written in a set of nested tenses. The first stanza takes place in the past, but then time moves forward when 'she thought, | recounting it later to her children' is placed in a continuing past tense. Then in turn, the pilot remembers his own father. When the daughter speaks her own mind, remembering what happened on her father's return, she explains how she also changed: 'till gradually we too learned | to be silent…' There is a palpable sadness about this memory, but also love and respect for the father, just as he sadly chose to value his family and peace over his own duty.

Why is English Pronunciation so Difficult

Why is English Pronunciation so Difficult Why is English pronunciation so difficult? One of the most confusing things about English is pronunciation. English has a total of 17tk spoken vowel sounds. This makes English  unusual, as most languages have 5-6. Spanish, for instance, has 5 vowel sounds, Mandarin 6, and Portuguese 9.English Pronunciation GuideAnother odd thing is that we  only use 5 letters  a,e,i,o and u to write all 17 sounds. Other languages, like Spanish or French, have 5 written vowels and 5 sounds.But what really makes English pronunciation difficult  is when your native language does not contain one of our vowel sounds. If youre language is like most, you have fewer vowel sounds than English has, which means there are going to be several sounds that youre going to have to learn how to make, but hear as well.A few years ago I did a language exchange with an Argentine friend. Wed speak for 45 minutes in English, then 45 in Spanish. At one point we started talking about pronunciation, and I explained that boo t and foot should have completely different sounds. My friend could not hear the difference between these two sounds, even when I said them one after the other. To an English speaker, there is a very clear difference.How do you learn how to produce a sound that you cant hear? Practice. Youll want to listen to how the sounds are made repeatedly, and get help making them. One of the most important parts of practicing English pronunciation is  learning  what you need to do  emphysically/em to make the sound. Learning exactly where your tongue and lips should be, and how wide open your mouth should be, can help produce that moment in which you suddenly find yourself making a sound you never knew existed. Its an exciting moment in learning!

How to Draw an Ellipse

How to Draw an Ellipse Did your math teacher confuse you when he or she introduced an ellipse (I dont mean an elliptical trainer here.)? Well, she has probably given the definition of an ellipse to you first. Perhaps, her words sounded like this. An ellipse is a curve on a plane surrounding two focal points such that a straight line drawn from one of the focal points to any point on the curve and then back to the other focal point has the same length for every point on the curve. While I think definitions are important they are often not a good way to start explaining a concept. Therefore, lets take a look at Saturns rings first: From the way we see them on Earth they form an ellipse. Loosely spoken they are an elongated circle in the shaped of an egg. How can one draw an ellipse? First, set up two points on paper. These two points form the foci of our ellipse. Next, connect these two points by a string longer than the distance between these points. Take a pen and move it along the stretched string. The path your pen moves precisely forms an ellipse. This animated picture visualizes the process. Ellipses are common in physics, astronomy and engineering. In 1609 the German mathematician Johannes Kepler famously proclaimed that the orbit of a plan of planets is an ellipse with the Sun at one of the two foci. Keplers discovery has been hugely influential in both the proliferation of the helio-centric model back then and space flight today.

Can I teach English abroad if Im a non-native speaker

Can I teach English abroad if I’m a non-native speaker Let’s cut to the chase. Yes, you absolutely can teach English abroad if you’re a non-native speaker! We’re happy to debunk this particular myth. At Teach Away, we regularly place teachers from all over the world, including native and non-native speakers, in lots of great teaching jobs abroad. Too many to count, in fact! The best part is, demand for English teachers worldwide is skyrocketing right now. Do you: Have a bachelor’s degree? Speak English proficiently? Hold a TEFL certification? Have a knack for teaching? If you check all of these four boxes, you're golden. There’s going to be the perfect English teaching job overseas out there for you. Especially in countries like China, where English language learners looking for great teachers like you are at an all-time high (check out the graphic below if you don't believe me): In fact, that’s why we launched a new initiative last year, called the Explore Program, to help recent college graduates land English teaching jobs with our partner schools in China. For all the details, check out the Explore Program page Don’t forget, English is a global language and in many instances, being a non-native speaker can actually give you an edge over your competition. Why’s that? Well, just think of how motivating you can be to your students as a non-native ESL teacher. As a bilingual teacher, you have so much to offer. For one, you’ve been in your students’ shoes before. You also worked hard to learn English to a high level, so you know what it’s like first-hand to learn a language from scratch. Secondly, you have a depth of understanding of English grammar concepts that your native speaking counterparts won’t have, having learned the language intuitively from birth. Remember, native English speakers don’t automatically make better English teachers. So, don’t let your nationality or accent hold you back from applying to teaching jobs abroad - schools abroad in many countries are looking for job candidates just like you! With all that said, let’s get down to the details: Who counts as a native English speaker? In general, employers abroad consider candidates from the US, Canada, the UK, Ireland, South Africa, Australia and New Zealand to be native English speakers. Hang on a second, that doesn’t seem fair, right? There are plenty of other countries that speak English as their primary language - countries in the Caribbean, the Philippines and India, to list just a few. The reality is, though, there are a few remaining countries that don’t count applicants outside of these seven countries as native English speakers. Stringent visa regulations in the UAE, South Korea and Japan, for example, require teaching candidates to hold a passport from one of the seven countries above, meaning schools in these countries are, unfortunately, restricted in who exactly they can hire. Where can I teach abroad as a non-native English speaker? Keep the chin up! There are still plenty of job opportunities for non-native English speakers in other popular teaching destinations overseas. The list is long: Thailand, Cambodia, countries in Central and South America like Mexico and Brazil, countries in Europe as well as Turkey, among others, all welcome applications from non-native English speakers. So, how can you make sure that you’re as qualified as possible for teaching positions in these countries? How non-native English speakers can boost their chances of being hired to teach English abroad. While being a non-native speaker isn’t necessarily a barrier to teaching English abroad, as with any job you apply for, you need to show you’re the right person for the job. When it comes to applying to teach English abroad, it’s important to first familiarize yourself with some common qualifications and requirements. Step 1 Head on over to the Teach Away job board and browse some job postings in the countries you’d like to teach in. This will help you figure out any gaps on your resume that could cost you that dream English teaching job interview. Sign up to Teach Away today for access to the latest teaching jobs around the world. Step 2 Ensure that you’re as qualified as possible for the English teaching jobs you’re interested in. Prove your teaching skills as well as your level of English fluency - taking a TEFL course can boost your chances of landing a job in one of the many and varied countries that welcome applications from non-native English speakers. Having some teaching experience also goes a long way to show your commitment when applying for English teaching jobs. This applies to native speakers just as much as non-native speakers, though! Remember to keep working on your English language skills, too. The English language is changing and adapting all the time. Read books, listen to English music, watch movies with the subtitles turned off - all of these daily activities will help you refresh your English skills! So get applying! Don’t let the fact that you’re a non-native speaker keep you from realizing your dream of becoming an English teacher abroad. Give it your best shot - keep honing those language skills, get your resume up to scratch, figure out where the best places to teach abroad are and keep an eye out for the right opportunities on our teach abroad job board. Good luck!
