Ethanol can be dehydrated to produce ethene gas.
ethanol→ethene+water \text{ethanol} \rightarrow \text{ethene} + \text{water} ethanol→ethene+waterIn an experiment, a student dehydrated 50.00 g of ethanol using a hot aluminium oxide catalyst.
The ethene gas was collected and its mass was determined.
The experimental data is shown in the table below:
| Mass in g | |
|---|---|
| Mass of ethanol reacted | 50.00 |
| Mass of ethene obtained from the reaction | 21.30 |
| Theoretical mass of ethene formed | 30.43 |
State the meanings of the terms actual yield and theoretical yield.
