👉 In chemistry, the term "autoxidize" refers to a chemical reaction where two or more reactants are combined in such a way that they combine completely without any exception. This process is often called a combustion reaction. For example, when hydrogen gas (H2) reacts with oxygen gas (O2), both reactants combine completely and no excess gases are produced. Similarly, when carbon dioxide gas (CO2) reacts with water vapor (H2O), all the CO2 molecules
