Восстановите пропуски в уравнениях реакций1. 2P + 3__ → 2PH3 2. Zn + 2HCL → ZnCl2 + __3. __ + H2O → 2NaOH 4. 4NH3 + __ → 4NO + 6__5. 3__ + 8HNO3 = 3Cu(NO3)2 + 4H2O + 2__ Заранее спасибо!

Answer 1

1. 2P + 3H2 → 2PH3
2. Zn + 2HCL → ZnCl2 + H2
3. NaO + H2O → 2NaOH
4. 4NH3 + O2 → 4NO + 6H2O
5. 3Cu(OH)2+ 8HNO3 = 3Cu(NO3)2 + 4H2O + 2NO

Answer 2

1. 2P + 3H2 → 2PH3 2. Zn + 2HCl → ZnCl2 + H2 3. CaO + H2O → 2NaOH 4. 4NH3 + 5O2 → 4NO + 6H2O 5. 3Cu + 8HNO3 = 3Cu(NO3)2 + 4H2O + 2NO2

Answer 3

1. 2P + 3H2 → 2PH3 2. Zn + 2HCl → ZnCl2 + H2 3. 2Na + 2H2O → 2NaOH + H2 4. 4NH3 + 5O2 → 4NO + 6H2O 5. 3Cu + 8HNO3 = 3Cu(NO3)2 + 4H2O + 2NO2
