Question

part b
which explanation best supports your answer to part 1?
the number of atoms from the reactants are present in the products, just rearranged.
the products gained extra mass because new atoms were created during the reaction.
the reaction type determined whether the products had more or less mass than the reactants.
some atoms from the reactants were used up or destroyed, so the total mass of the products is lower.

Explanation:

According to the law of conservation of mass in chemical reactions, atoms are neither created nor destroyed. They are just rearranged from reactants to form products.

Answer:

The number of atoms from the reactants are present in the products, just rearranged.
