Question

Hydrogen reacts with oxygen to produce a pale blue-colored flame.

• A. True
• B. False

Answer 1

The correct option is A True

• Hydrogen undergoes combustion in the presence of oxygen with a pale blue-colored flame and forms water vapor along with heat energy.
• The chemical reaction can be represented as,

$\underset{\mathrm{Hydrogen}}{{\mathrm{H}}_2\left(\mathrm{g}\right)}+\underset{\mathrm{Oxygen}}{{\mathrm{O}}_2\left(\mathrm{g}\right)}\to \underset{\mathrm{Water}\mathrm{vapor}}{{\mathrm{H}}_2\mathrm{O}(\mathrm{g}})+\mathrm{heat}$

Therefore, the given statement is true.
