When iron sulfide (FeS)(FeS) is combined with hydrogen chloride (HCl)(HCl) , a gas is formed in a double-displacement reaction. Which gas would it be?

Explanation:

Below is an attachment containing the solution.

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 .

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.
