Question

why a balanced chemical equation is needed

Answer 1

In calculations, a balanced chemical reaction is a condition that makes the calculations possible. A balanced equation reflects how many molecules or atoms of one substance are required to produce molecules or atoms of other substance. Without balancing, we cannot make predictions on the results of chemical reactions and cannot find the mass of products using the mass of reactants or vice versa.
