MgO--Mg--Mg(OH)2--MgOHCL--MgCl2--AgCl
1. MgO + C = Mg + CO
2. Mg + 2H2O = Mg(OH)2↓ + H2↑
3. Mg(OH)2 + HCl(нед) = MgOHCl + H2O
4. MgOHCl + HCl(изб) = MgCl2 + H2O
5. MgCl2+ AgNO3 = AgCl↓ + Mg(NO3)2
MgO + C → Mg + CO Mg + 2H2O → Mg(OH)2↓ + H2↑ Mg(OH)2 + HCl→ MgOHCl + H2OMgOHCl + HCl → MgCl2 + H2OMgCl2+ AgNO3 → AgCl↓ + Mg(NO3)2

Verified answer
MgO + C → Mg + CO
Mg + 2H2O → Mg(OH)2↓ + H2↑
Mg(OH)2 + HCl→ MgOHCl + H2O
MgOHCl + HCl → MgCl2 + H2O
MgCl2+ AgNO3 → AgCl↓ + Mg(NO3)2
