The chemical equations for copper are as follows:
1, copper reacts with oxygen to form copper oxide: 2Cu+O2→2CuO.
2, copper reacts with silver nitrate solution to form copper nitrate solution and silver: 3Cu+8AgNO3+2=CuNO32-3AgCl-2H2O.
3, copper reacts with concentrated sulfuric acid to form copper sulfate, sulfur dioxide and water: Cu+2H2SO4 concentrated→ CuSO4+SO2↑+2H2O. p>3, copper and concentrated sulfuric acid reaction to produce copper sulfate, sulfur dioxide and water: Cu + 2H2SO4 concentrated → CuSO4 + SO2 ↑ + 2H2O.
4, copper and dilute hydrochloric acid reaction to produce copper chloride and hydrogen: Cu + 2HCl → CuCl2 + H2 ↑.
