What is the word equation for the decomposition of hydrogen peroxide, H2O2?

The decomposition of hydrogen peroxide, H2O2, involves the breakdown of the compound into its simpler components, which are water (H2O) and oxygen (O2). The correct word equation accurately reflects this chemical change, stating that hydrogen peroxide decomposes to form water and oxygen. This reaction is often catalyzed by substances such as manganese dioxide or catalase in biological systems, but the essential reaction remains the same.

Understanding this process is crucial as it demonstrates the concept of a decomposition reaction, where a single substance breaks down into two or more simpler products. In this case, hydrogen peroxide, when decomposed, releases oxygen, which is a characteristic reaction that can be observed through the bubbling or effervescence due to the release of gas.

The other options do not correctly represent the reaction involving the decomposition of hydrogen peroxide. They either describe formations or reactions that do not involve the breakdown of H2O2 into water and oxygen specifically.
