The chemical equation for the process of photosynthesis is shown. Which statement describes how this chemical equation provides evidence for the Law of Conservation of Mass?

The total number of carbon, hydrogen, and oxygen atoms in the reactants and products is the same; the atoms are just rearranged.

The total number of oxygen atoms in the reactants is the same as the number of hydrogen atoms in the products; the atoms are combined.

The total number of carbon, hydrogen, and oxygen atoms is greater in the products than in the reactants; the reactants form new substances.

The total number of carbon, hydrogen, and oxygen atoms is greater in the reactants than in the products; mass decreases in the products.

Two students are asked to present a chemical change in science class. In container A, they place a penny in water. In container B, they place a penny in nitric acid. The results are shown. What container shows a chemical change occurring?

Container B, because a gas is produced

Container A, because a new substance is formed

Container A, because the penny does not dissolve
