the world ends.
Yes, it is amphoteric, at the same time it behaves like acid AND like base: it acts as an acid when in a base: ZnO(s) + 2OH-(aq) +H20(l) -> [Zn(OH)4]2-(aq) it reacts as a base when in acid: ZnO(s)...
Zirconium dioxide (ZrO2) is an amphoteric oxide: with acidic and basic properties simultaneously.
No, nitric oxide is acidic
Yes it is an amphoteric oxide as it has both basic oxide and acidic oxide properties.
