Answer:
Hydrogen is a highly reactive fuel. Hydrogen molecules violently react with oxygen when the existing molecular bonds break and new bonds are formed between oxygen and hydrogen atoms. ... But hydrogen does not react with oxygen at room temperature, a source of energy is needed to ignite the mixture.
