Question

Здравствуйте! Помогите уравнять химические реакции (в молекулярной есть, в полной и сокращённой ионной формах) 1) CH3COOH+KOH=CH3COOK+H2O 2) Mg+2CH3COOH=Mg(CH3COO)2+H2 3) 2CH3COOH+Na2CO3=2CH3COONa+CO2+H2O 4)MgO+2CH3COOH=Mg(CH3COO)2+H2O

Answer 1

1)
CH3COOH+KOH ⇒ CH3COOK+H2O
СН3СОО⁻+Н⁺ + К⁺+OH⁻ ⇒ CH₃COO⁻+K⁺ + H₂O
H⁺+OH⁻ = H₂O
2)
2CH3COOH + Mg => (CH3COO)₂Mg + H₂↑
2CH₃COO⁻ + 2H⁺ + Mg => 2CH₃COO⁻ + Mg²⁺ + H₂↑
2H⁺ + Mg => Mg²⁺ + H₂↑
3)
2CH3COOH+Na2CO3 => 2CH3COONa+CO2↑+H2O
2CH3COO⁻ + 2H⁺ + 2Na⁺ + CO₃²⁻ => 2CH3COO⁻+2Na⁺+CO₂↑+H₂O
2H⁺ + CO₃²⁻ => CO₂↑ + H₂O
4)
MgO+2CH3COOH => (CH3COO)₂Mg + H2O
MgO + 2CH3COO⁻ + 2H⁺ => 2CH3COO⁻ + Mg²⁺ + H₂O
MgO + 2H⁺ => Mg²⁺+H₂O
