Ethanol may be converted into ethanoic acid by passing it over hot copper(II) oxide. $\text{CH}_3\text{CH}_2\text{OH} + 2\text{CuO} \rightarrow \text{CH}_3\text{COOH} + \text{H}_2\text{O} + 2\text{Cu}$ What kind of reaction is this?
- Aprecipitation
- Bredox
- Cthermal decomposition
- Dneutralisation
