The table shows information about some compounds of carbon.
| Compound | Formula |
|---|---|
| A | C3H6\text{C}_3\text{H}_6C3H6 |
| B | C2H5OH\text{C}_2\text{H}_5\text{OH}C2H5OH |
| C | C2H5COOH\text{C}_2\text{H}_5\text{COOH}C2H5COOH |
| D | C4H10\text{C}_4\text{H}_{10}C4H10 |
| E | C6H14\text{C}_6\text{H}_{14}C6H14 |
Compound A belongs to the homologous series called the alkenes. What is the general formula of the alkenes?
Which homologous series does compound C belong to?
Compound A, C3H6\text{C}_3\text{H}_6C3H6, burns in a limited supply of oxygen to undergo incomplete combustion, producing carbon monoxide, CO\text{CO}CO, and water, H2O\text{H}_2\text{O}H2O. Write the balanced symbol equation for this reaction.
In a car's catalytic converter, carbon monoxide and nitrogen monoxide react according to the equation:
2CO+2NO→N2+2CO2 2\text{CO} + 2\text{NO} \rightarrow \text{N}_2 + 2\text{CO}_2 2CO+2NO→N2+2CO2During a journey, 42 g42\text{ g}42 g of nitrogen, N2\text{N}_2N2, is produced. Calculate the volume of nitrogen monoxide, in dm3\text{dm}^3dm3, removed from the exhaust gases. (Take the molar gas volume at RTP as 24 dm3/mol24\text{ dm}^3/\text{mol}24 dm3/mol. Relative atomic mass: N=14.0\text{N} = 14.0N=14.0)
