Question

The chemical equation for zinc in hydrochloric acid is: Zn + HCI = ZnCl2 + H2

Does the above equation demonstrate the law of conservation of mass as it is currently written? Explain why or why not.

Answer 1

Answer: No it does not

Step-by-step explanation:

The law of conservation of mass states that mass is neither created nor destroyed and in this equation you start with 1 molecule of Cl and 1 of H, but on the reactants side you end up with 2 of each. To make it follow the law of conservation of mass you would have to balance the equation
