What is Hydrogen Combustion? (with pictures)
Jul 07, 2019· Hydrogen combustion is the process by which hydrogen reacts with an oxidizing agent and burns. Hydrogen combustion is an exothermic combustion, meaning that it releases heat energy. Endothermic processes, on the other hand, absorb energy. Hydrogen burns based on the chemical formula 2H 2 + O 2 → 2H 2 O, meaning that it reacts with oxygen.
