Emulsion Definition Chemistry

Emulsion Definition ChemistryThe word 'emulsion' just describes what it means to 'mix.' It simply means combining two liquids or substances and allowing them to flow through one another.The definition of a 'queen' in chemistry and physics is the most complex and most interesting. A queen, in this instance, is defined as a single molecule which has a positive charge in an ionic liquid. In aqueous solution the concentration of aqueous charge density in solution can be described by using the algebraic expression, where c is the concentration and of the displacement. Let's look at an example for demonstration purposes:- c = 17.5 eV (equations 6.24)c - current density in aqueous solutionc = -17.5 eV (compressibility of aqueous solution)d - concentration in the solventd = -0.88c = -17.5 eVc = -17.5 eVc = -17.5 eV- aqueous density- c = -17.5 eV- c = -17.5 eVc = -17.5 eVc = -17.5 eVSo now we know that it is important to apply aqueous force to aqueous solution in order to cause both molecules to move, but how do we get both molecules to move? We get an emulsion by applying a small negative charge to the negative ends of the molecules and letting them mix. This forces the negative ends of the molecules to meet up with the positive ends of the other molecules and form a chemical bond that makes the two molecules move together, much like a slipper on a two-year old girl's foot.

Solving by substitution Online Tutoring - Maths Tutors

Solving by substitution Online Tutoring - Maths Tutors Substitution is a very useful method in mathematics. In the method of substitution one of the variable is substituted to find the other variables and vice versa. It helps reduce the given question or solution to a simpler form. Expressions can consist of one or more than one unknown variables with different coefficients and constant numbers. Example 1: Solve by substitution the set of equations 3x + 2y = 12 and x + y = 6? Solution: The given equations are 3x + 2y = 12 and x + y = 6. Here x, y are the unknown variables. Substitute the variable x. From one equation x = 6 - y, substituting in the other equation. This gives 3(6-y) + 2y = 12; 18 - 3y + 2y = 12; 18 -y = 12; y = 6. Now substitute y = 6 in x + y = 6; x = 0. Hence the solution is x = 0 and y = 6. Example 2: Solve by substitution the set of equations x - y = 0 and 2x + 5y = 7? Solution: The given equations are x - y = 0 and 2x +5 y = 7. Here x, y are the unknown variables. Substitute the variable x. From one equation x = y, substituting in the other equation. This gives 2y + 5y = 7; 7y = 7; y =1. Now substitute y = 1 in x = y; x = 1. Hence the solution is x = 1 and y = 1

(Source: Crazy Banana)A tutor will provide their student with a method to help them progress during a lesson. However, they can't constantly look over their student’s shoulder outside of cla ss. This means that the student needs to practice on their own.How often should a student work individually on their piano exercises?It takes regular practice to learn how to play the piano: playing for three hours once in a while or just before your lessons isn’t enough to improve and will probably render your lessons ineffective. You need to focus and memorize things.You could say that you should practice the piano whenever you want. This might sound a bit like a cliché but you should play whenever you feel like playing. Just make sure when you do that it’s effective practice and not just messing around.Doing two hours of practice before your tutorials is a quick way to slow down your progress. It’s essential to put aside some time every day to practice playing the piano. At least half an hour a day should be enough. Making sure that you practice a certain piece means that you’ll have to stop doing whatever you were doing instead.What if you can’t read the piece from yo ur last piano lesson? Have a look on-line for tutorials. There are plenty of free piano lessons on-line and video tutorials that could help. A quick on-line search should get you the results you're looking for.However, if you’re genuinely motivated and want to learn, you won’t feel like you’re giving up any time at all.  We recommend thirty minutes of practice after dinner before you turn on the TV. This is when you tend to be at your most creative.However, there’s no one-size-fits-all solution. Everyone learns differently. You need to find the routine that works for you. Some people learn more quickly than others.  Some people may learn something in an hour while others may need four hours. It completely depends on your motivation.However, there are some things than anyone wanting to become a pianist should know:Practice should always be enjoyable.You need to focus and activate your memory in order for any learning to be effective.The more you practice, the more your finger s will separate and the easier you’ll find playing across several octaves. You’ll gain more and more dexterity. How Can I Improve My Dexterity?Improving their dexterity really annoys a number pianists. However, your private tutor can help you work on this.When we say dexterity, we're talking about your ability to quickly and accurately navigate the keyboard with your hands, especially when the notes are fairly far apart.Dexterity can improve how well you hit your piano targets. (Source: Wikimedia Commons)When you first start, your hands will probably be fairly stiff. The quickest way to improve your dexterity is to practice:do exercises going up and down octaves.learn to go from one chord to another quickly and fluidly.do exercises to improve your finger span: flex your fingers.play scales on the piano: start slowly and then get faster and fasterwork on common chord progressionsget used to not looking at your fingers when you’re playing.You’ll soon start to make more and mor e progress. These exercises will be hugely beneficial in the long-term, especially if you’d like to one day be able to sing and play at the same time, compose your own music, and become a skilled and well-rounded pianist in the process.Once you feel comfortable playing your scales at relatively quick speed, start working on your coordination by playing sections with your left hand, then your right, and finally combing the two together. First slowly, then more quickly.You should always practice your scales just before your lessons. First C major, then D major, etc. It’s good for warming up your fingers and mentally preparing your ear for music. Having a good knowledge of your scales is also great for improvising with other musicians.A budding musician should master their scales in order to learn as quickly and as effectively as possible.

It’s basically playing two instruments at the same time and it's not easy.Singing and playing at the same time may be difficult but it's not impossible. (Source: PeakPX)Even a privately taught pianist can forget everything when they have to start singing.To sing and play at the same time, you have to first master the piano part, then the singing part, then bring the two parts together.  When bringing the two parts together, you need to both coordinate your two hands then synchronize them with your voice.In the same way you coordinate your two hands when learning to play the piano, you’ll have to repeat the same process in order to sing while you play. It’s recommended that you start with a fairly simple song with a simple chord progression and no vocal gymnastics.  Choose a song in common time (4/4) in C-major, for example.You should also try playing the song while humming before you try singing along. This allows you to focus on the vocal melody and the piano part. This means you won’t get distracted by trying to rem ember the lyrics.If you really want to learn to sing and play piano at the same time, you need to learn your source material inside out. You need to know every vocal nuance by heart.To summarize, here are the key points for singing and playing piano at the same time:Be patient, determined, and persevering.Adopt a good posture for playing and singing.Play the piano part and practice the singing part separately.Choose a simple song.Play the song while speaking (to see if you know it well enough).Listen to the original song a lot.Break down the lyrics into syllables.Use a metronome or tap your foot to keep time.More complex songs require more work. Perhaps you need to simplify the music itself.Your private tutor should be able to help you with simplifying the piece.Has your search for piano lessons London yielded satisfactory results?

How Can You Simplify a Piano Piece?It might be beneficial to simplify the piece in order to make it mo re playable on the piano.Being able to simplify piano music is one of your most important tools. (Source: Tanner Randall)Some songs are incredibly complex, unreadable, or contain substitutions (which are very common in jazz).Simplifying a song by making it more playable on the piano is sometimes necessary if the person playing the piece doesn’t have the necessary level to play the song in all its complexity. This is much better than discouraging the pianist.It’s also a good idea to listen to the song plenty of times before trying to simplify it.  Make a note of the chords as you listen and play them on the piano. This practice will help you get to know the song much better than just listening to it.Identify the chords, then practice the chord progression, starting off slowly and getting faster and faster until you’re playing at the same tempo as the song. You have to work out the main chords in order to pick apart a song.Finding the root note of each chord is essential when it comes to analyzing a song.  The pianist can then work out the chord’s harmonies and whether the chord is a major chord, minor chord, a fifth, seventh, etc.  You need to be familiar with music theory in order to do this.If you’ve been working on your dexterity, you should be able to put these chord progressions together yourself. How Do You Compose a Piano Piece?Here’s some advice for composing a piece for piano: Know your music theory and think creatively.To become a composer, you need to be inspired. (Source: pxhere)Have a good technical ability: you can’t compose as a beginner.  You need to know how to put chords together, their inversions, common rhythms, etc.You also need to have a good knowledge of music, different genres and styles, etc.  Be familiar with reading sheet music: reading sheet music like you would a book.  You need to encourage imagination and creativity in order to compose a piece on piano. It’s difficult but also very rewarding.Use a metronome to impr ove your rhythm. It might be annoying to listen to but it’ll ensure that you’re always in time. Make sure you know your time signatures. Is this going to be a waltz or a march?Choose the right chords to work with the feel of your piece. Remember that minor chords tend to give a piece a melancholic feel. On the other hand, major chords feel optimistic and happy. You also need to think about the lyrics. Make sure the chords go well together: certain progression evoke certain feelings.Once you’ve considered all this, you need to work out how you’re going to play it.You can use the chords to focus on the the song’s rhythmic qualities. What about deconstructing the chords and playing them as arpeggios to give the song a more melodic quality.Don’t forget to record your creations!  Sometimes you’ll come up with nothing. However, sometimes you’ll stumble upon something amazing. You’d hate to forget what it was, right?  With a microphone and a music program, you can start p utting your ideas together and working on them.  It’s always a good idea to record yourself when you’re improvising.  Then you can listen back to it and write down what you did. Make sure your theory’s good.Becoming a pianist is basically and long and difficult journey. However, this is what’s so beautiful about the piano. It’ll be worth it in the end!

Choosing the Right SAT Subject Tests

Choosing the Right SAT Subject Tests During the test preparation process, the sheer number of tests and test dates can be overwhelming. Here at AJ, we have an expert knowledge of college entrance exams and can help you navigate the journey. Here’s a brief guide to one test (the SAT Subject Test, or SAT II) and how students can choose the right ones for them.OverviewUnlike the SAT, which is broad and covers many skills and content areas, the SAT Subject Tests focus on specific subjects taught in school. Because students are already preparing for finals at the end of the junior year, May and June are ideal months to take the SAT Subject tests. Acing the SAT Subject tests is a great way to show what you’ve learned throughout the year.There are 20 SAT Subject Tests, each of which is an hour in length, scored from 200-800, and comprised entirely of multiple choice questions. You can take up to 3 tests per test date, but we often find that 1-2 is ideal due to potential test day exhaustion.Factors to Consider in Choosing a TestYou can see a complete list of SAT Subject Test offerings here. The best way to see which SAT Subject tests are right for you is to take practice tests and score them. Here are a couple of key guidelines that can help along the way.1. College GoalsAdmission requirements around SAT Subject Tests vary widely among colleges. Many elites schools require or recommend 2-3 SAT Subject Tests. Examples include Brown University, Georgetown University, Caltech, Rice University, and Tufts University. You can find specific requirements on every school’s website, so it’s a valuable exercise to sit down and make a list of what your student will need to include in the application. If even a couple of your student’s top choices require or recommend SAT Subject Tests, it will be wise to have him or her pick exams and schedule a test date.2. The Student’s Strengths and CourseworkAP courses often translate well to the SAT Subject Tests, so if, for example, a student is excelling in AP Biol ogy and AP English Language Literature during her junior year, the SAT Biology and SAT Literature should be strong contenders for a May or June test date. Keep in mind that, while the AP’s and SAT’s often have much content overlap, there are certainly differences, and the formats are quite different. AP Exams rely more on essays and long-form responses as opposed to the strict multiple-choice format of the SAT’s. Thus, it’s important to be strategic and plan on preparing for both the AP and SAT separately towards the end of the course.3. CoachabilityIn addition to any solid AP coursework or obvious subject test affinities, we find that the Math II and Literature exams are great choices for many students. A junior who has taken or is taking pre-calculus will have completed all necessary coursework for both exams. Furthermore, these exams are especially coachable and strategic in nature, and our students have historically seen a great deal of success and improvement on these exams. For example: while we have an excellent record of success with all of the subjects, our biggest score increases come from the Math Level 2 SAT Subject Test, with many students improving over 100 points.How to Prepare for the TestsAJ Tutoring knows the SAT Subject Tests with a degree of expertise bordering on obsession. Luckily for students, a minimalistic approach focusing on a few key test-taking strategies, a series of full-length practice exams, and a targeted content review can work wonders in maximizing performance on test day.Our SAT Subject Test Students typically complete 3-4 sessions of 1.5 hours each. They start with an hour-long practice exam which serves as a jumping off point for a highly customized preparation beginning with session #1. In a 1-on-1 format, the tutor will observe the student’s strengths and weaknesses and tailor the instruction to fit his or her needs, assigning practice, reviewing gaps, and coaching on question evaluation as they go.You can le arn more about our preparation process here.Please reach out to us today to make a test prep plan for your student!
