Ответ:
CaCl₂ + 2AgNO₃ ⟹ 2AgCl↓ + Ca(NO₃)₂
Ca²⁺ + 2Cl¯ + 2Ag⁺ + 2NO₃¯ ⟹ 2AgCl↓ + Ca²⁺ + 2NO₃¯
Cl¯ + Ag⁺ ⟹ AgCl↓
MgO + 2HNO₃ ⟹ Mg(NO₃)₂ + H₂O
MgO + 2H⁺ + 2NO₃¯ ⟹ Mg²⁺ + 2NO₃¯ + H₂O
MgO + 2H⁺ ⟹ Mg²⁺ + H₂O
2KOH + Cu(NO₃)₂ ⟹ Cu(OH)₂↓ + 2KNO₃
2K⁺ + 2OH¯ + Cu²⁺ + 2NO₃¯ ⟹ Cu(OH)₂↓ + 2K⁺ + 2NO₃¯
2OH¯ + Cu²⁺ ⟹ Cu(OH)₂↓
