thanks for helping, buy my question is why it wouldnt react with HCl and react with HNO3.

Yeah. It answers half of your question. It says that Copper doesn't react with non-oxidizing acids, such as HCl.  Chem Experts here would no doubt know the answer for you question.

it says Cu doesnt but CuO does....my question is Cu+2 would that be the same as CuO??

I'll address them in reverse order:

1) "it says Cu doesnt but CuO does....my question is Cu+2 would that be the same as CuO??" - The answer is no. Cu²⁺ is an aqueous ion, meaning that it exists in solution as Cu²⁺. The Cu atom in CuO does have a +2 charge but CuO doesn't dissociate into Cu²⁺ and O^2- in aqueous solution.

2)"figure out why Cu+2 cant react with HCl but still reacts with HNO3"
can anyone explain why this is true?" ; "It says that Copper doesn't react with non-oxidizing acids, such as HCl." - The key word has been highlighted. Think on it a bit. Get back to us is you still have problems.
