Solution

Answer
Hydrogen is a highly reactive fuel.
hydrogen molecules( $H_{2}$ ) react violently with oxygen( $O_{2}$ ), when the existing molecular bonds break and new bonds are formed between oxygen and hydrogen atoms.
As the products of the reaction are at a lower energy level than the reactants, the results is an explosive release of energy and production of water.
But the hydrogen does not react with oxygen at room temperature, a source of energy is needed to ignite the mixture.
Chemical equation :
$2 H_{2} (g) + O_{2} (g) \overset{}{\underset{lit}{\to} 2 H_{2} O} (l)$
