The compound formed when hydrogen burns in the air are Water.

Combustion of Hydrogen

• Hydrogen is a combustible gas
• It burns in air, (that is it is reacting with oxygen) and produces water.

$\underset{\mathrm{Hydrogen}\mathrm{gas}}{2{\mathrm{H}}_2\left(\mathrm{g}\right)}+\underset{\mathrm{Oxygen}\mathrm{gas}}{{\mathrm{O}}_2\left(\mathrm{g}\right)}\to \underset{\mathrm{Water}}{2{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)}$

• If a large number of hydrogen burns in the air, it leads to an explosion. this is because hydrogen combines with oxygen violently.
• When it is made to burn at the end of a jet, it burns with a blue flame.
