Preparation of salts — practice question

Copper(II) oxide reacts with dilute ethanoic acid. Which equation correctly represents this reaction?

  • A$\mathrm{CuO} + \mathrm{CH}_3\mathrm{COOH} \rightarrow \mathrm{CH}_3\mathrm{COOCu} + \mathrm{H}_2$
  • B$\mathrm{CuO} + \mathrm{CH}_3\mathrm{COOH} \rightarrow \mathrm{CH}_3\mathrm{COOCu} + \mathrm{H}_2\mathrm{O}$
  • C$\mathrm{CuO} + 2\mathrm{CH}_3\mathrm{COOH} \rightarrow (\mathrm{CH}_3\mathrm{COO})_2\mathrm{Cu} + \mathrm{H}_2$
  • D$\mathrm{CuO} + 2\mathrm{CH}_3\mathrm{COOH} \rightarrow (\mathrm{CH}_3\mathrm{COO})_2\mathrm{Cu} + \mathrm{H}_2\mathrm{O}$
