Answer:
C3H8 + 5O2 === 3CO2 + 4H2O
Explanation:
The balancing of a chemical equation is simply based on Law of conservation of mass which states that mass can neither be created nor be destroyed but it only changes from one form to another during a chemical reaction. According to this law, the tottal number of atoms of each element on both sides of the equation must be same. By following this rule, we just have to make sure that the if there are three number of Carbon atoms on the left hand side ( Reactant side) then there must be same number of Carbon atoms on the right hand side which is called product side. The number of Hydrogen( H )atoms, Oxygen (O) atoms are balanced on the same principle.
