importance of chemistry 101

Half-life period of a nuclide The time taken to reduce the number of nuclei to one half the origina..

Shapes of s orbitals - s orbitals are non-directional and spherically symmetrical, This means that the probability of finding the electron is same in all directions at a particular distance from the nucleus, The 1s orbital is shown in the figure 1.3. fig 1.3 - Shapes of 1s and 2s orbitals It is obs..

Electrode Potential - It is important to understand the development of charges at the electrodes. When a strip of a metal M is placed in a solution of its ions M n + , a metal - metal ion electrode is obtained. The possible processes that can occur at the electrodes are: The metal ion M n..

Importance of Chemistry - The branch of science, which deals with the study of matter, its composition, its properties and the changes that it undergoes in composition as well as in energy during various processes, is defined as chemistry. It has been further divided i..

The branch of science, which deals with the study of matter, its composition, its properties and the changes that it undergoes in composition as well as in energy during various processes, is defined as chemistry. It has been further divided into different branches depending upon sp..

1 mole of an atom = 1 gram atomic weight of an atom 1 mole of a molecule = 1 gram molecular weight of molecule 1 mole of a gas = 22.4 liters of gas at STP 1 mole of a substance = 6.023 x 10 2 3 , atoms, molecules or ions Molecular weight = 2 x Vapor density 1 molar volume = ..

Importance of Steoreochemistry - Stereochemistry, an important aspect of carbon compounds, is a feature that is widely prevalent in nature. The human body is structurally chiral with the heart lying to the left and the liver to the right. Many climbing plants show chirality in t..

Vitamin A This is a fat soluble vitamin which is present mostly in animals. Its provitamins carotenes are found in plants. Vitamin A is necessary for vision and proper growth. It is necessary for maintenance of proper immune system to fight various infections. Cholesterol synthesis req..
