A. What is the total mass of the reactants?

B what is the total mass of the products?
C. How does this reaction demonstrate the conservation of mass?

A. To find the total mass of the reactants, you would need to add up the individual masses of each reactant involved in the reaction.

B. To find the total mass of the products, you would need to add up the individual masses of each product formed in the reaction.

C. This reaction demonstrates the conservation of mass because the total mass of the reactants is equal to the total mass of the products. This is because in a chemical reaction, matter is neither created nor destroyed, only rearranged into different molecules. Therefore, the total mass before the reaction is the same as the total mass after the reaction.
