Synthesis of Water

2H2 + O2 → 2H2O

Tổng quan

Hydrogen gas reacts with oxygen gas to produce water. This highly exothermic reaction releases a large amount of energy and is one of the most fundamental chemical reactions known. It is the basis of hydrogen fuel cells and was the cause of the Hindenburg disaster.
