What are 4 basic rules for balancing chemical equations

A well balanced chemical equation should have fulfilled coefficient, formula and chemical state aspects.

Explanation:

The formula of the reactants should be written on the left followed by an arrow and the products on the right. The reactants and the products must be well written correctly in chemical formula. The number of atoms of elements in the reactants side must be equal to that of the products therefore one should count the atoms of an element on both sides to ensure that they are equal. All the elements must be balanced, hence, balance an elements one at a time using possible lowest whole numbers that are written as coefficients to the chemical formula. Chemical symbols of the products and reactants are not similar for atoms therefore no balancing should be done by changing chemical symbols.
