Answer 1

1.

4 NH₃ + 3 O₂ = 2 N₂  + 6 H₂O

4 NH₃ + 5 O₂ = 4 NO + 6 H₂O

4 NH₃ + 7 O₂ = 4 NO₂ + 6 H₂O

3 N₂O + 2 NH₃ = 4 N₂ +3 H₂O

2 H₂S + 3 O₂ = 2 SO₂ + 2 H₂O

2 NO₂ + 4 H₂ = N₂ + 4 H₂O

2NO₂ -> 2NO + O₂

2N₂O₅ = 4NO₂ + O₂

2.

a) 2Al + 3S= Al₂S₃

b) 2N₂O= 2N₂ + O₂

c) Fe₂O₃ + CO = 2FeO + CO₂

d) MnO₂ + H₂ = MnO + H₂O

e)2Mg+ CO₂= 2MgO + C

f) 2FeO + C = 2Fe + CO₂

g) 2Fe+ 3Cl₂ = 2FeCl₃

h) PbO₂ + 2H₂ = Pb + 2H₂O
