WebMar 30, 2024 · 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. While it is not shown in the chemical equation, an input of energy is necessary to begin the reaction, which releases a significant amount of energy when carried through to completion. WebAnswer (1 of 3): The key point is that many/most chemical reactions can be classified in more than one way. We’ll use your example. \mathrm{2H_2 + O_2 \rightarrow 2H_2O} can be classified as * a redox reaction: hydrogen is oxidized, oxygen is reduced. * a recombination reaction: four hydroge...
