what is a chemical equation and balanced chemical equation


Chemical Equations:  It is the symbolic representation of a chemical reaction where the reactant entities are given on the left hand side and the product entities on the right hand side of the equation. In complete chemical equation all reactants and products are written along with their physical state. A chemical equation must be balanced so that it can follow the law of conservation of mass. For example
C +  O2 → CO2
What is a balanced chemical equation ?
Balanced Chemical equation: If in a chemical equation the total number of atoms in the reactant side are equal to the total number of atoms in the product side then the chemical reaction is said to be balanced.
