Know the Answer?

Henry Barber · Answer 1

Answer is: D) It was turned into smoke and gas.

Conservation of mass (mass is never lost or gained in chemical reactions), during chemical reaction no particles are created or destroyed, the atoms are rearranged from the reactants to the products.

Gas that escaped is probably carbon (IV) oxide and little carbon (II) oxide, so the mass of product measured is less than reactants.

If mass of gas is also measured, masses of reactants and products are the same.

Its D. Because the rest of the mass turned to gas
