Solution

The correct option is C Law of conservation of mass
The law of conservation of mass depicts the "equality of masses between the reactants and the products".
It states that matter can neither be created nor be destroyed, it can only be changed from one form to the other.
Ethanoic acid + Sodium Carbonate $\to$ Sodium ethanoate + Carbon dioxide + Water
6 gm + 5.3 gm = 8.2 + 0.9 + 2.2 = 11.3 gm.
