Answer

MgCl₂ ⟵ HCl ⟶ FeCl₂
Mg + 2HCl ⟶ MgCl₂ + H₂
Fe + 2HCl ⟶ FeCl₂ + H₂
KAlO₂ ⟵ KOH ⟶ K₂ZnO₂
2Al + 2KOH + 2H₂O⟶ 2KAlO₂ + 3H₂ [g]
Zn + 2KOH ⟶ K₂ZnO₂ + H₂[g]
ZnO ⟵ H₂O ⟶ Fe₃O₄
Zn + H₂O ⟶ ZnO + H₂ [g]
3Fe + 4H₂O ⇌ Fe₃O₄ + 4H₂ [g]
CO + H₂ ⟵ H₂O ⟶ CO₂ + H₂
$\underset{\text{coke}}{\text{C}} + \underset{\text{steam}}{\text{H}$
$\underset{\text{water gas}}{[\text{CO} + \text{H}$
NH₃ ⟵ H₂ ⟶ H₂S
N₂ + 3H₂ ⇌ 2NH₃
H₂ + S ⟶ H₂S
