Which process generally occurs when oxygen is removed from a substance?
Answer and explanation
Correct answer: Reduction
Removal of oxygen from a substance is called reduction. For example, in
\(\mathrm{CuO + H_2 \rightarrow Cu + H_2O}\), oxygen is removed from copper(II) oxide, so
\(\mathrm{CuO}\) is reduced. In contrast, oxidation involves the addition of oxygen to a substance.
