Question 16
F

Ethanoic acid reacts with magnesium to form a salt and a gas. The ethanoate ion is CH3COO−\mathrm{CH_{3}COO^{-}}CH3​COO− and the magnesium ion is Mg2+\mathrm{Mg^{2+}}Mg2+.

Which equation is correct?

[1]
A

2CH3COOH+Mg→Mg(CH3COO)2+H2\mathrm{2CH_{3}COOH + Mg \rightarrow Mg(CH_{3}COO)_{2} + H_{2}}2CH3​COOH+Mg→Mg(CH3​COO)2​+H2​

B

2CH3COOH+2Mg→2MgCH3COO+H2\mathrm{2CH_{3}COOH + 2Mg \rightarrow 2MgCH_{3}COO + H_{2}}2CH3​COOH+2Mg→2MgCH3​COO+H2​

C

2CH3COOH+Mg→Mg(CH3COO)2+H2O\mathrm{2CH_{3}COOH + Mg \rightarrow Mg(CH_{3}COO)_{2} + H_{2}O}2CH3​COOH+Mg→Mg(CH3​COO)2​+H2​O

D

4CH3COOH+Mg→Mg(CH3COO)4+2H2\mathrm{4CH_{3}COOH + Mg \rightarrow Mg(CH_{3}COO)_{4} + 2H_{2}}4CH3​COOH+Mg→Mg(CH3​COO)4​+2H2​
