Question 3 10 pts
Which ratio of reactants to products supports the law of conservation of
mass?
O 1:1 because the mass of the reactants before the reaction is equal to the mass of the
products after the reaction
O 1:0 because the mass of the reactants is completely used up during the reaction so
the products have no mass after the reaction
O 2:1 because the mass of the reactants is halved during the reaction
1:2 because the mass of the reactants is doubled during the reaction
