Products always have a different physical and chemical state than reactants.
The total mass of the reactants must equal the total mass of the products.

Answer 1

Answer: The total mass of the reactants must equal the total mass of the products.

Explanation: This is because the mass of all reactants is the mass of all products. Remember that escaping gases from products can lessen the mass. But in all, all products have the same mass as the reactants. I hope this helps!
