Hydrochloric acid is formed by disolving HCl (a gas) into water. Sulfuric acid is formed by disolving H2SO4 (a liquid) in water. Pure H2SO4 is a clear syrupy liquid that absorbs any water in the air and gives off a smokey looking vapor if it is exposed to the air, but it isn't a gas, consequently sulfuric acid is not prone to off gassing unless you get it very hot.
Hydrogen gas is given off when magnesium reacts with sulfuric acid.
Hydrochloric acid gives off hydrogen gas when it reacts with certain metals, such as magnesium or zinc. When hydrochloric acid reacts with limestone (calcium carbonate), carbon dioxide gas is produced.
When magnesium reacts with dilute hydrochloric acid, it gives off hydrogen gas.
Hydrochloric acid gives off hydrogen gas (H2) when it reacts with certain metals like magnesium or zinc.
No acid is formed. The reaction produces hydrogen gas and magnesium chloride, a salt.

Chlorine gas (Cl2)
Carbon dioxide gas is given off when a carbonate reacts with dilute hydrochloric acid. This reaction results in the formation of a salt, water, and carbon dioxide gas.

Hydrochloric acid evaporates off of potassium sulfate when it's produced. This results because potassium chloride is combined with sulfuric acid to create potassium sulfate.
When powdered iron metal is added to hydrochloric acid, hydrogen gas is given off as a product. This reaction also forms iron(II) chloride as a result.
I have no idea. The products of that reaction are water (not a gas at room temperature) and potassium chloride (not a gas at room temperature).
