Chris investigates the conservation of mass during a chemical reaction. He measures the mass of the reactants before the reaction, and the mass of the products afterward.
He then shares his results with Garett. Garett says that the experiment was not valid.
Which of the following would be best for Chris to validate his results?

A) Repeat the experiment several times to make sure the results are reliable.

B) Use different compounds for the reaction so the experiment will proceed faster.

C) Publish his findings in a scientific journal so that other scientists can easily read his results.

D) Start the experiment with a different mass to make sure that the law of conservation of mass is observed.
