Depends on it's oxidation state. It can be Cu2+ for copper (II) or it can be Cu+ for copper (I)
Pure gold is just that: gold. However, when used for jewelry or coins, it usually has copper mixed in for better durability.
It depends ~ if it's copper(I), then the formula is Cu2CO3, but if it's copper(II), the the formula is CuCO3
The formula for cuprous oxide is Cu2O. The formula for copper is just Cu, although many copper items are not pure copper.
The formula for copper(II) sulfide is CuS the formula for copper(I) sulfide is Cu2S.
Copper(II) sulfate has the formula CuSO4.
Copper Metalic
