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 hydro chloric acid solution
-adding hot water to the solution
-using magnesium powder instead of a large piece of magnesium
-increasing pressure on the system

A. and C

Explanation:

using hot hydro chloric acid solution

(just took it on edg)

It's the first and third one. On Edgenutiy

Explanation:

1. using hot hydrochloric acid solution

2. using magnesium powder instead of a large piece of magnesium

the reaction mixture contains some ammonia, plus a lot of unreacted nitrogen and hydrogen. the mixture is cooled and compressed, causing the ammonia gas to condense into a liquid. the liquefied ammonia is separated and removed. the unreacted nitrogen and hydrogen are then recycled back into the reactor .
