The Balanced equation is:
C3H8 (g) + 5O2 (g) –> 3CO2 (g) + 4H2O (g)
A balanced equation of a chemical reaction is said to be so if both the products and the reactants have the same number of atoms and total charge for each component of the reaction. In other words, either side of the chemical reaction have an equal balance of mass and charge.
The inclusion of stoichiometric coefficients to the products and reactants is necessary to have balanced equations. This is significant because an equation must adhere to the laws of conservation of mass as well as constant proportions, meaning that both the reactant and product sides of the equation must include the same quantity of atoms of each element.
