Question

Suppose you were to heat the copper in argon gas instead of atmospheric gasses. Given that argon is relatively inert, which of the following would you expect if you were to heat pure copper in the presence of argon gas?

A) There would be no copper oxide formed and the mass of the copper would not change with heating

B) The copper oxide yield would be higher.

C) Copper argon would form, increasing the mass of the product.

D) The copper oxide yield would be lower.
