Question

Which chemical equation best represents the Law of Conservation of Mass?

A. H + O -> H2O
B. H2 + O2 -> H2O
C. 2H2 + O2 -> 2H2O
D. H2 + O2 -> 2H2O

Answer 1

C

Option C shows a balanced equation between the reaction of hydrogen and oxygen to form water and a balanced equation complies with the law of conservation of mass which states that matter is neither created nor destroyed but changed from one form to another.

Answer 2

The chemical equation that best represents the Law of Conservation of Mass is 2H₂ + O₂ → 2H₂O. This equation is balanced, with the same number of hydrogen and oxygen atoms on both sides of the equation.

Step-by-step explanation:

The chemical equation that best represents the Law of Conservation of Mass is:

2H₂ + O₂ → 2H₂O

This equation is balanced, with the same number of hydrogen and oxygen atoms on both sides of the equation. The Law of Conservation of Mass states that the total mass of the reactants must be equal to the total mass of the products in a chemical reaction.
