Question

product formeed when hydrogen burns in air​

Answer 1

Explanation:

In a flame of pure hydrogen gas, burning in air, the hydrogen (H2) reacts with oxygen (O2) to form water (H2O) and releases energy. If carried out in atmospheric air instead of pure oxygen, as is usually the case, hydrogen combustion may yield small amounts of nitrogen oxides, along with the water vapor.

Answer 2

Water

heat

2H2(gas) + O2(gas) = 2H2O(liquid)
