When ignited, hydrogen gas combines with oxygen gas explosively in proportions ranging from 4.1 - 71.5% hydrogen - ignition temperature is ca. 580 °C. The gaseous reaction is 2 H 2 (g) + O 2 (g) → 2 H 2 O (g) This exothermic reaction yields 232 kJ/mol of water formed.

Hydrogen molecules violently react with oxygen when the existing molecular bonds break and new bonds are formed between oxygen and hydrogen atoms. As the products of the reaction are at a lower energy level than the reactants, the result is an explosive release of energy and the production of water.

Here, 2 moles of hydrogen gas reacts with 1 mole of oxygen gas to form 1 mole of water. And 2 moles of hydrogen gas have mass 4 gram, 1 mole of oxygen gas have 32 gram mass. So, the ratio of hydrogen to oxygen is 1: 8. For reacting 8gm of hydrogen, we need 64 gm of oxygen.

If oxygen is needed for fires to burn and hydrogen is a highly explosive gas, why does water not explode when exposed to fire? Asked by: Corey Hartman Answer Another question from the "good old questions" list. Let me start with a short answer: Water will not explode, because it already has "burned". It is true that hydrogen is an explosive gas, and it also needs oxygen to burn. But the key point lies in this question: What is burning? The answer is that burning is the process of reacting ...
