What is a reaction called in which hydrogen is removed from a substance or oxygen is added to it?
Answer and explanation
Correct answer: Oxidation
The governing concept is oxidation–reduction. Oxidation is identified by the addition of oxygen or the removal of hydrogen from a substance; loss of electrons is another related definition. Therefore, the reaction described is oxidation, so option A is correct. Reduction is the opposite process, involving removal of oxygen or addition of hydrogen. Displacement and neutralisation describe different reaction patterns.
