The name of the gas is hydrogen.
For example, when a magnesium ribbon is put into some dilute hydrochloric acid in a test tube, magnesium reacts with the acid to form magnesium chloride solution and hydrogen gas.
Mg(s) + 2HCl(aq) → MgCl₂(aq) + H₂(g)
Test of hydrogen gas :
Hydrogen gas burns with a 'pop' sound.
