Сокращенное ийонное уравнение
1)Zn+2CH3COOH➡️(CH3COO)2Zn+H2⬆️
2)CaO+2CH3COOH➡️(CH3COO)2Ca+H2O
3)NaOH+CH3COOH➡️CH3COONa+H2O
4)K2CO3+2CH3COOH➡️2CH3COO+H2O+CO2⬆️

Answer 1

Zn+ 2CH₃COOH = (CH₃COO)₂Zn+H₂
Zn+ 2CH₃COO⁻ + 2H⁺ = 2CH₃COO⁻ + Zn²⁺ + H₂
Zn+  + 2H⁺ =  Zn²⁺ + H₂

СaO + 2CH₃COOH = (CH₃COO)₂Ca + H₂O
CaO+ 2CH₃COO⁻ + 2H⁺ = 2CH₃COO⁻ + Ca²⁺ + H₂O
CaO +  2H⁺ =  CaO + H₂O

NaOH + CH₃COOH = CH₃COONa + H₂O
Na⁺ + OH⁻ + CH₃COO⁻ + H⁺ = CH₃COO⁻ + Na⁺ + H₂O
OH⁻ +  H⁺ =  H₂O

K₂CO₃ + 2CH₃COOH = 2CH₃COOK + H₂O + CO₂
2K⁺ + CO₃²⁻ + 2CH₃COO⁻ + 2H⁺ = 2CH₃COO⁻ + 2K⁺ + H₂O + CO₂
CO₃²⁻ +  2H⁺ =  H₂O + CO₂
