Solution

Acids react with metals to form hydrogen gas and the respective salt. [0.5 Marks]

Iron and dilute $H_{2} {S O}_{4}$ react as follows:

$Fe(s) + H_{2} {S O}_{4} (dil) \to + {FeSO}_{4} (aq) + H_{2} (g)$ [1 Marks]

Hydrogen gas is evolved in this reaction. [0.5 Marks]

When hydrogen gas is ignited with a burning matchstick, it puts out the fire with a 'pop' sound. [1 Marks]
