Question

magnesium reacts with hydrochloric acid to form hydrogen gas and magnesium chloride: mg(s) + 2hcl(aq) → mgcl₂(aq) + h₂(g) which actions would increase the rate of reaction? check all that apply. using hot hydrochloric acid solution adding hot water to the solution using magnesium powder instead of a large piece of magnesium increasing pressure on the system retry

Explanation:

Increasing temperature (using hot hydrochloric acid solution) speeds up reaction as particles move faster and collide more frequently. Using magnesium powder increases surface - area, providing more sites for reaction. Adding hot water dilutes the acid, decreasing reaction rate. Changing pressure has little effect on this reaction as only one gas is involved and its volume change is not significant in the context of this reaction.

Answer:

using hot hydrochloric acid solution, using magnesium powder instead of a large piece of magnesium
