Bài 4: Hoàn thành các PTHH sau:

a, ? + ? → CH3COONa + H2

b, ? + ? → CH3COONa + H2O + CO2

c, CH3COOH + ? → (CH3COO)2Ca + ? + ?↑

d, ? + Mg → (CH3COO)2Mg + ?↑

Answer 1

a) \(2Na+2CH_3COOH\rightarrow2CH_3COONa+H_2\)

b) \(Na_2CO_3+2CH_3COOH\rightarrow2CH_3COONa+CO_2+H_2O\)

c) \(2CH_3COOH+CaCO_3\rightarrow\left(CH_3COO\right)_2Ca+H_2O+CO_2\)

d) \(2CH_3COOH+Mg\rightarrow\left(CH_3COO\right)_2Mg+H_2\)

Answer 2

\(a) 2Na+2CH_3COOH→2CH_3COONa+H_2 \)

\(b) Na_2CO_3+2CH_3COOH→2CH_3COONa+CO_2+H_2O \)

\(c) 2CH_3COOH+CaCO_3→(CH_3COO)_2Ca+H_2O+CO_2↑ \)

\(d) 2CH_3COOH+Mg→(CH_3COO)_2Mg+H_2↑\)
