Answer 1

Answer:

Search by products (Zn(NO 3) 2, NO 2, H 2O)

1 HNO3 + Zn → H2O + NO2 + Zn(NO3)2

2 HNO3 + Zn → H2O + NO2 + NH4NO3 + Zn(NO3)2

3 HNO3 + Zn → H2O + NO + NO2 + Zn(NO3)2

4 HNO3 + ZnS → H2O + H2SO4 + NO2 + Zn(NO3)2

Answer 2

Explanation:

Zn + 4 HNO3 → Zn(NO3)2 + 2 NO2 + 2 H2O

This is an oxidation-reduction (redox) reaction:

Zn0 - 2 e- → ZnII

(oxidation)

2 NV + 2 e- → 2 NIV

(reduction)

Zn is a reducing agent, HNO3 is an oxidizing agent.

Reactants:

Zn
