2CH3COOH+Na->CH3COONa+H2
CH3COOH+Na2CO3->CH2COONa+h2O+CO2
2CH3COOH+CaCO3->(CH3COO)2Ca+H2O+CO2
2CH3COOH+Mg->(CH3COO)2Mg+H2
a) 2CH3COOH + 2Na → CH3COONa + H2
b) 2CH3COOH + Na2CO3 → CH3COONa + H2O + CO2
c) CH3COOH + ? → (CH3COO)2Ca + ? + CO2↑
d) 2CH3COOH + CaCO3 → (CH3COO)2Mg + H2O + CO2↑
Bài 4: Hoàn thành các PTHH sau:
a, Na + CH3COOH → CH3COONa + \(\dfrac{1}{2}\)H2
b, Na2CO3 + 2CH3COOH → 2CH3COONa + H2O + CO2
c, 2CH3COOH + CaCO3 → (CH3COO)2Ca + H2O + CO2↑
d, 2CH3COOH + Mg → (CH3COO)2Mg + H2↑
