Answer:
when atoms lose or gain electrons
Explanation:
To balance a chemical equation, place coefficient as needed in front of the symbols or formulas of the elements. So the same number of each type of atom occurs in both reactants and products.
Steps to be followed are-
(1) Write down the chemical reaction in the form of word equation, keeping all the reactants on left hand side and keeping products on right hand side.
(2) Write all the symbol and formula of all reactants and products in word equation.
(3) Balance the whole equation by multiplying the symbols and formula by smallest possible figures.
Same number of each and every atom, of same type occurs in both reactants and products.
Once all the individual elements are balanced, then the total number of atoms of each element on the reactant and product side are compared once again after balancing. If there are no inequalities, the chemical equation is said to be balanced.
