Chemical property
The copper sheet can only be heated in an alcohol lamp to form CuO, which is difficult to oxidize in dry air, but easily oxidized in humid air to form basic copper carbonate (2Cu+O2+H2O+CO2==Cu2(OH)2CO3). Compared with copper sheet, copper powder is more easily oxidized because the surface is in more contact with air.
Copper can be burned in chlorine gas to produce brown-yellow smoke, resulting in copper chloride (Cu+Cl2= ignition =CuCl2).
