List of Chemistry Formulas Important Concepts and Terms

The branch of science dealing with the chemical and physical properties of substances in a manner that further results in the formation of new substances is known as Chemistry. In the history of mankind, all elements have received a specific name derived from chemistry studies. The formulas of chemistry are known as chemical formulas.

How to Write Chemical Formulas?

1. Valency can be used to write chemical formulas for binary compounds composed of two different elements.
2. Valency refers to the capacity of an element to combine with another element to form a compound.
3. First, the valencies of the two elements should be determined. Then, the sums of the valencies of the two elements should be equal by specifying the common lowest multiple of the valencies.

Steps to Write a Chemical Reaction

1. The right number of reactants is written on the left side of the equation.
2. Formulas for the products are written on the right side of the equation.
3. Reactants and products are separated by arrows pointing towards the products. This arrow indicates "to produce".
4. The plus sign indicates "reacts with" on the reactants side, and it means "and"  on the products side.
