What is Substance Chemistry?

What is Substance Chemistry?Definition of Substance Chemistry is very important. Chemists in chemical industry use this term to indicate the relationship between an element and its chemical symbol, so that, for example, Oxygen is defined as O 2 and Hydrogen is H2O.Definition of Substance Chemistry is the study of elements, their molecular bonds, and reactions with each other. It also includes other chemical elements that are not defined by chemical symbols such as all the natural elements and all the compounds of natural elements. Chemistry is the study of chemical reactions. Definitions of various phenomena in chemistry can be divided into three main categories: macroscopic phenomena (such as light scattering or absorption, wavelength and wave length) and microscopic phenomena (such as atomic structure, ionic composition, molecular motion, physical or chemical equilibrium).Macroscopic chemical reactions are the result of the interaction of molecules of two different elements with ea ch other. Micropotential mechanical properties are the basis of the composition of many biomolecules such as enzymes, lipids, proteins, nucleic acids and DNA. Microscopic chemical reactions are reactions that take place in or on the surface of a specimen.Properties are generally expressed as a sum of their quantitative components. Molecular dimensions, vibrational frequencies, etc. are usually considered as properties.Most properties are recognized by their chemical symbols. For example, the melting point is defined as P o = K o. When we talk about temperature, we need to add an 'x' to the name of the property to indicate that it has been changed. For example, instead of saying 'x = K o' we should say 'x + K o' or 'x + K (K) o'.Substances in everyday life include gases, liquids, solids, liquids and solids. The names of the properties are usually related to the chemical constitution of the substance. For example, Zn is an element which is both an ion and metal. Therefore it has both the properties of a metal and an ion.Properties are usually determined experimentally and by spectroscopy. A number of properties are really independent of the properties of the atoms. Different atomic models exist for a given substance.

4 Tips for Staying Focused and Organized as Junior Year Gets Busy

4 Tips for Staying Focused and Organized as Junior Year Gets Busy The following is a guest post written by Anna Carapellotti of Admissionado, a premier college admissions consulting company focused on helping students get into their dream schools. With winter break a little under a month away, were sure all of you are looking forward to some much-deserved relaxation. But in the meantime, youre probably feeling the pressure of pending exams and final papers, as well as the need to keep thinking about college applications. To help you put forth your best effort, weve compiled a list of things to help you stay focused and organized during the upcoming monthand then again in the new year! 1. Minimize distractions First things first, put your smartphone away and close Facebook on your computer. By minimizing the distractions posed by social media while studying, writing, etc., you will be able to get through your work more efficiently and effectively, as well as save more quality time for rest and relaxation, your family, and friends. In addition to minimizing the digital distractions, its important to find yourself a tidy, quiet place to work. If you have your own desk in your bedroom, keep it clean and uncluttered. If you dont have this luxury, find a quiet place elsewhere in your home, or plan to go to your local library when you have work to do. [RELATED: 4 Things NOT to Let Slide During Senior Year] 2. Develop a system for organizing your work Whether you use paper or a laptop, its important to keep your work organized. This will prevent you from losing assignments or forgetting to do them in the first place. Moreover, taking the time to develop a filing system on your desktop (or one on your literal desk) will make studying for your cumulative mid-year and final exams much easier. 3. Make to-do lists As your responsibilities increase (and trust us, they will only continue to do so), you may find yourself losing track of everything you need to do. It can be helpful to make lists of the things you need to accomplish, and it can be incredibly satisfying to mark off the things you have completed. So, regardless of whether you choose to use scraps of paper or something a bit more sophisticated on your smartphone, taking note of the things youd like to accomplish in the short-term can pave the way to what you would like to achieve in the long-run! 4. Keep a consistent schedule With a standard school day and extracurricular activities filling your afternoons, chances are your schedule is already pretty consistent. However, you can take your organizational skills to the next level by sticking to another sort of schedule in your downtime. Perhaps you could set aside Sunday afternoons to get organized, make your weekly to-do list, and spend some time looking at information about colleges, or you could set aside a certain block of time each evening during the week for reading and studying. This level of consistency will ensure that you make time for what is important. As you can see, tackling the remainder of junior year in an organized and focused fashion will be easy! By simply minimizing distractions and developing systems to organize your time and work, you will help ensure that you will accomplish a great deal in the short-term and will set yourself up to succeed in the long-run as well!

These are incredibly cheap since its just you, your hammock, and the sky. This is a unique and cheap way to experience Brazil.You can also find holiday villages and campsites along the coast in coastal resort towns. Just like in Europe, they aren’t necessarily the most interesting places and they’re not necessarily more comfortable than the hotels you’d find in the city . The advantage is that they’re geared towards tourists.  If you want a relaxing time in Brazil, holiday villages are a good way not to get homesick.Finally, for a successful holiday, make sure you check that where you want to stay is available.

Despite how awkward this may seem, these deals sell like hotcakes.Don’t forget that it’s a good idea to learn a bit of Portuguese to make things easier once you arrive and to get cheap flights using sites like Skyscanner.

You'll need a tourist visa from the Brazilian government before you go. This is easily obtained by applying to the Brazilian embassy or consulate and will be valid for five years.Finally, before you visit Brazil, you should get a yellow fever vaccination!Keep in mind that Portuguese is the official language of Brazil (not Spanish like most other South American countries), so you might want to brush up on your language skills before you go.You can always get a bit of help from one of the many talented tutors on Superprof. There are three main types of tutorial available on the site: face-to-face tutorials, online tutorials, and group tutorials. There are pros and cons to each and the best one for you really depends on your situation.Face-to-face tutorials are the most personal and have you and your tutor working together for the whole session. If shyness has been getting in the way of your language learning, this is prob ably the best option. Additionally, the tutor can tailor each lesson to exactly what you need to learn or what you've been struggling with.Online tutorials are similar to face-to-face tutorials and you're more likely to find native Portuguese speakers as you can broaden your search to anywhere in the world!In group tutorials, there are several students and just one tutor. With all the students sharing the cost of the tutor's time, these tutorials are usually the cheapest per person per hour but each student won't get the bespoke tutoring or one-on-one time that they would in the other types of tutorials.

12 Sided Polygon

12 Sided Polygon A geometric shape which is enclosed by 12 lines is known as 12 sided polygon, it is also known asdodecagon. The area of a regular polygon: The area of a regular polygon of n sides = (na^2/4) cot( /n) (1) Where a is the length of a side of the polygon. In particular, if a be the length of a side of a regular hexagonthen it means n= 6, now we can substitute n= 6 in equation (1) =(6a^2 / 4) cot ( / 6) =(33 / 2) a^2 Example: - What is the area of dodecagon. Solution: - Since 12 sided polygon is known as dodecagon. Therefor n = 12 The area of a regular polygon of n sides= (na^2/4) cot( /n) = (12 a^2 / 4) cot ( / 12). Now we need to find the value of cot ( / 12). Suppose a/2 = / 12 a = 2( /12) = /6 Since cot (a/2) = (1 + cos a) / sin a Therefore, cot ( /12) = [1 + cos ( /6)]/ sin ( / 6) = (1 + 3/2) / (1/2) = (2 + 3) Therefore Area of a dodecagon = 3(2 + 3) a^2 Example 2: - If each sides of dodecagon are 5 cm then find the area of dodecagon. Solution: - According to the problem a= 5 then Area of dodecagon = 3 (2 + 3) a^2 = 3 (2 + 3) 5^2 = 75 (2 + 3)
