Question

4. What is a balanced chemical equation? Why should chemical equations be balanced?​

Answer 1

Answer:

Those reactions in which the number of atoms involved in the reactant side is equal to the number of atoms in the product side is called balanced equation.

Skeletal chemical equations are unbalanced . We need to balance chemical equations because of law of conservation of mass . It states "during a chemical reaction matter is neither created nor destroyed. " Therefore chemical equations must be balanced in each and every chemical reaction . Only a balanced equation tell us the relative quantities of different reactants and products involved in the reaction.

Answer 2

A balanced chemical equation has an equal number of atoms of different elements in the reactants and products .

The chemical equations should be

balanced to satisfy the law of

conservation of mass .
