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.

Hi, @Brostep0s how can I help you?

Hi, @Brostep0s allow me to explain this:

well the mass would be the same as the sum of the individual substances , and according to the law of conservation of mass , whatever mass you have in the reactants must be the same that you going to have in the product after the reaction.

HCl's mass is 36.46 g/mol. Magnesium's mass is  24.305 g.

Would the mass simply sum together after the reactant is formed, or would some of the mass transpire due to the reaction?

librarian · Answer

I believe the mass would simply sum together after the reactant is formed.

That's all I needed. Thank you for the effort.

No problem @Brostep0s have a wonderful day.
