This article is based on the most important subject of our education, that is chemistry. Chemistry is the study of the science of matter, especially its properties, structure, composition, behavior, reactions, interactions and the changes it undergoes. It is also called as the central science, as it connects physics with other natural sciences or we can say that it connects physics with natural matters like astronomy, biology etc.
Chemistry is subdivided into two parts which are organic chemistry and inorganic chemistry. Inorganic chemistry is basically a branch of chemistry concerned with the properties and behavior of inorganic compounds. Organic chemistry is basically a scientific study of the structure, properties, composition, reactions, and preparation of carbon-based compounds, hydrocarbons, and their derivatives. Organic compounds are organic in nature and consists of carbon - carbon covalent bond while inorganic compounds are mineral in nature and don't consist of carbon - carbon covalent bond.
chemistry homework help is a very renowned online tutorial and helping the students by completing their statistics based home work and assignments. Now- a-days students have to do many things at a time as he/she needs to be active or all rounder. So it is not possible for all time to complete their projects or home work or assignments within deadline and in proper manner. To solve this problem there are various websites or chemistry tutor available online which provide assignments and projects on various subjects through email etc.
Online tutoring is that in which you study chemistry with tutors who have many years of experience of teaching chemistry across grades. So they are not only experts in the subject, but also have extensive experience in working with students across grades and levels.
Homework helper can solve any kind of chemistry problems. Few of the topics which is covered by Online tutoring are:
Atomic and Molecular
Structure Conservation of Matter and Stoichiometry
Acids and Bases
Chemical Thermodynamics
Chemical Equilibrium
Nuclear Processes
Chemical Bonds
Gases and their Properties
Solutions
Reaction Rates
Organic and Biochemistry
Let's take an example to understand it better. A compound is composed of 5.045g of carbon, 0.847g of hydrogen, and 3.36g of oxygen. Find the empirical formula for this compound knowing that H = 1 g/mole , O = 16 g/mole and C = 12 g/mole
First, convert the grams of each element to moles:
5.045/12 = 0.42 mole C , 0.847/1 = 0.847 mole H , 3.36/16 = 0.21 mole O
Divide each of the three mole figures by the lowest of the three in order to simplify the mole ratio.
0.21/0.21 = 1 mole O , 0.42/0.21 = 2 mole C , 0.847/0.21 = 4 mole H
Well, that's 1O ,2C and 4H
The resulting simplest whole number empirical formula is C2H4O
