POAC stands for Principle Of Atom Conservation which is used to solve a chemical equation.
there is no need of balancing the equation if we adopt POAC. It is based on the conservation
of mass of an atom or mole of an atom
Example KClO3 can be taken
KClO3 = KCL + O2
Moles of K IN KClO3(Reactant) = Moles of K in KCl(product)
