CAIE A-Level Chemistry AS 2.3.2 Balanced and Ionic Equations Questions question 1

[Maximum number: 1]

Three equations are shown.

1CH3COOH+MgCO3→CH3COOMg+CO2+H2O23CH3CH2COOH+Na→CH3CH2COONa+12H23CH3CH2COOH+2Ba(OH)2→CH3CH2COOBa2+2H2O\begin{aligned} & 1 \mathrm{CH}_{3} \mathrm{COOH}+\mathrm{MgCO}_{3} \rightarrow \mathrm{CH}_{3} \mathrm{COOMg}+\mathrm{CO}_{2}+\mathrm{H}_{2} \mathrm{O} \\ & 2 \\ & 3 \mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{COOH}+\mathrm{Na} \rightarrow \mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{COONa}+\frac{1}{2} \mathrm{H}_{2} \\ & 3 \mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{COOH}+2 \mathrm{Ba}(\mathrm{OH})_{2} \rightarrow \mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{COOBa}_{2}+2 \mathrm{H}_{2} \mathrm{O} \end{aligned}
