Question

if copper is being reacting to nitric acid is it a chemical or physical change

Answer 1

The reaction of copper with nitric acid is a chemical change. During this reaction, copper reacts with nitric acid to produce copper nitrate, nitrogen dioxide, and water, resulting in the formation of new substances. Chemical changes involve the breaking and forming of bonds, leading to the creation of different chemical compounds, whereas physical changes do not alter the chemical composition of a substance.
