A chemist is studying a reaction involving the reaction of magnesium and hydrochloric acid to produce hydrogen gas a magnesium chloride. The method that she will likely use to measure the rate of reaction is
a) measuring the volume of gas used up
b) measuring the volume of gas produced
c) measuring the volume of liquid used up
d) measuring the volume of magnesium chloride produced
e) measuring the volume of magnesium produced

b) measuring the volume of gas produced
are you sure?
Yes, I am sure. When magnesium reacts with hydrochloric acid, one of the products is hydrogen gas. Therefore, by measuring the volume of gas produced, the chemist can determine the rate at which the reaction is occurring.
