Is hydrogen peroxide decomposition exothermic
WitrynaTraductions en contexte de "réaction de décomposition de l'eau" en français-anglais avec Reverso Context : Une réaction de décomposition de l'eau s'effectue pour produire de l'oxygène gazeux (O2). WitrynaThis decomposition reaction usually happens slowly. You can observe the speed of the decomposition happening as bubbles form when the hydrogen peroxide is poured into a container. When yeast is mixed in with the hydrogen peroxide, the yeast causes this decomposition chemical reaction to occur much more quickly.
Is hydrogen peroxide decomposition exothermic
