Question Question 4
What is a balanced chemical equation? Why should chemical equations be balanced?
A balanced equation is one in which the number of atoms of each element of the reactant is equal to the number of atoms of each element of the products.
An equation must be balanced in order to comply with the "Law of Conservation of Mass", which states that mass is neither created nor destroyed in the course of a chemical reaction. An unbalanced equation would imply that atoms have been created or destroyed.
