The correct answer is A. oxidation.
Oxidation is a chemical reaction that involves the loss of electrons or an increase in oxidation state. In the reaction between compounds and oxygen, the compounds lose electrons to oxygen, which is why oxidation is also called a redox reaction.
Hydrolysis is a chemical reaction in which water is used to break down a compound. Carbonation is a chemical reaction in which carbon dioxide is added to a compound to form a carbonate salt. Solution is a state of matter in which a solute is dissolved in a solvent.
In the reaction between compounds and oxygen, the compounds are the reactants and oxygen is the reactant. The products of the reaction are the compounds that have been oxidized and oxygen gas.
The following is an example of an oxidation reaction:
2H2 + O2 â 2H2O
In this reaction, hydrogen gas is oxidized to water. The hydrogen atoms lose electrons to the oxygen atoms, which is why the oxidation state of hydrogen increases from 0 to +1. The oxidation state of oxygen decreases from 0 to -2.
Oxidation reactions are important in many chemical processes, including combustion, respiration, and rusting.
