WebDec 29, 2024 · Hydrogen is an extremely flammable gas. It can cause severe explosions if not handled with care. The fires caused due to hydrogen explosions are unseeable. Also, hydrogen leakages are difficult to detect as it is colorless and odorless. The enthalpy of combustion of hydrogen gas is −286 kJ/mol. Combustion Hydrogen gas (dihydrogen or molecular hydrogen) is highly flammable: 2 H2(g) + O2(g) → 2 H2O(l) (572 kJ/2 mol = 286 kJ/mol = 141.865 MJ/kg) The enthalpy of combustion is −286 kJ/mol.
