Confusing question

Answer 1

If you were to measure the mass of magnesium and hydrochloric acid before combining them in the test tube, how would that mass compare to the mass of reactants left in the test tube after the reaction? Explain your answer and how it corresponds to the law of conservation of mass

Answer 2

The mass would remain the same. There may be a chemical reaction taking place, but that only rearranges what's initially there. No matter how much a substance is rearranged, the amount will still be equal throughout the process. Hope that helps.
