Chemical properties of copper
Copper reacts with oxygen to form copper oxide.
Copper reacts with bases to form sulphates.
Readily combines with water and carbon dioxide producing hydrated copper carbonate.

Uses of copper
All US coins are now copper alloys, and gun metals also contain copper. Most copper is used in electrical equipment such as wiring and motors. This is because it conducts both heat and electricity very well, and can be drawn into wires.
