Write the reactions of interaction of zinc oxide with sulfuric nitric and phosphoric acid and potassium hydroxide.

First of all, you need to remember that ZnO is an amphoteric oxide and it interacts with acids and alkalis. When interacting with acids, salt and water are always formed.
1.ZnO + H2SO4 => ZnSO4 + H2O
2.ZnO + 2HNO3 => Zn (NO3) 2 + H2O
3.3Zno + 2H3PO4 => Zn3 (PO4) 2 + 3H2O
4.ZnO + 2KOH => K2ZnO2 + H2O (the reaction occurs when this oxide and alkali fusion: potassium zincate and water are obtained)
