Why is Cr2O3 an amphoteric oxide and CrO a basic oxide? Is there an easy method by which we can identify if an oxide is acidic, basic neutral or amphoteric?

I am not sure about your 1st question but can sure give you a method to identify I'd an oxide is acidic or basic. Check the oxidation number of the central atom. Higher the oxidation number more acidic oxide it is. For ex. P2O5 is more acidic than P2O3 where the oxidation states are +5 and +3 respectively.
