Question

1)N2+?=NH3 2)NH3+?=(NH4)3PO4 3)NH3+?=NH4NO3

Answer 1

1)N2+3H2=2NH3

 2)3NH3+H3PO4=(NH4)3PO4

3)NH3+HNO3=NH4NO3 

Answer 2

N₂ + 3H₂ = (при p, t, катал.) = 2NH₃

3NH₃ +  H₃PO₄ = (NH₄)₃PO₄

NH₃ + HNO₃ = NH₄NO₃

Answer 3

1. The balanced chemical equation for the reaction of nitrogen gas (N2) with an unknown reactant to produce ammonia (NH3) is:

N2 + 3H2 → 2NH3

The unknown reactant is hydrogen gas (H2), and the balanced chemical equation is:

N2 + 3H2 → 2NH3

2. The balanced chemical equation for the reaction of ammonia (NH3) with an unknown reactant to produce ammonium phosphate ((NH4)3PO4) is:

3NH3 + H3PO4 → (NH4)3PO4

The unknown reactant is phosphoric acid (H3PO4), and the balanced chemical equation is:

3NH3 + H3PO4 → (NH4)3PO4

3. The balanced chemical equation for the reaction of ammonia (NH3) with an unknown reactant to produce ammonium nitrate (NH4NO3) is:

NH3 + HNO3 → NH4NO3

The unknown reactant is nitric acid (HNO3), and the balanced chemical equation is:

NH3 + HNO3 → NH4NO3
