which two statements describe how the law of conservation of mass applies to chemical reactions?
the atoms of the reactants are rearranged to form the products.
the number of reactant compounds and the number of product compounds must be the same.
the products and reactants must weigh the same.
the states of matter of the reactants and products must weigh the same.

Explanation:

The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction. Atoms are just rearranged from reactants to products, and the total mass of reactants equals the total mass of products. The number of reactant and product compounds doesn't have to be the same, and it's not about the states of matter weighing the same but the overall mass.

Answer:

• The atoms of the reactants are rearranged to form the products.
• The products and reactants must weigh the same.
