Question

pls help
This is a chemical reaction for the decomposition of carbonic acid into water and carbon dioxide. How does the reaction support the Law of Conservation of Mass?
Several molecules of the water are produced
The mass of carbon atoms is reduced during the reaction
The mass of the atoms in the reactant equals the mass of the atoms in the products
The mass of hydrogen atoms is the only thing that remains the same before and after the reaction

Answer 1

Answer:

The answer for above question is

Because in law of conservation of mass nor energy is destroyed or produced. so a balanced equation can be the example
