Write the reaction equation: Zn- zno -znso4- zn- zno -zn (no3) 2

1. Combustion of zinc metal in a stream of oxygen.

2Zn + O2 = 2ZnO.

2. Reaction with sulfuric acid.

ZnO + H2SO4 = ZnSO4 + H2O.

3. Decomposition of zinc sulfate.

ZnSO4 = Zn + S + O2.

4. Reaction of zinc with water vapor, t = 600-800 ° C.

Zn + H2O = ZnO + H2.

5. Reaction with nitric acid.

ZnO + 2HNO3 = Zn (NO3) 2 + H2O.
