What is a balanced chemical equation? Give one example of a balanced chemical equation.
According to the law of conservation of mass, mass is neither created nor destroyed. So, the atoms of each element in the reactant side and the product side should be the same.Such equations which follow the law of conservation of mass are termed as balanced chemical equations.
An example of a balanced chemical equation is:
CaO(s) + H2O(l) → Ca(OH)2(aq)
