What is the chemical formula of copper oxide?

Answer 1

Well... you'll have to specify the oxidation state of copper. Is it #+1# or #+2#? Is it copper(I) or copper (II)? Your pick.

Depending on your choice, it may be #"CuO"# or #"Cu"_2"O"#... Which one is which, if oxygen in this compound, the oxide anion #"O"^(2-)#, has an oxidation state of #-2#?

In this day and age, if you're not sure, you should be able to google the chemical formula. (If you're really focused, you can even click the chemical formulas themselves up above.)

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
