The table shows information about some compounds of carbon.
| Compound | Formula |
|---|---|
| P | C2H4\text{C}_2\text{H}_4C2H4 |
| Q | C3H7OH\text{C}_3\text{H}_7\text{OH}C3H7OH |
| R | CH3COOH\text{CH}_3\text{COOH}CH3COOH |
| S | C3H8\text{C}_3\text{H}_8C3H8 |
| T | C5H12\text{C}_5\text{H}_{12}C5H12 |
Compounds S and T belong to the homologous series called the alkanes. What is the general formula of the alkanes?
Which homologous series does compound R belong to?
Compound P, C2H4\text{C}_2\text{H}_4C2H4, 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, 242 g of carbon dioxide is produced. Calculate the volume of carbon monoxide, in dm3\text{dm}^3dm3, removed from the exhaust gases. (Take the molar gas volume at RTP as 24 dm3/mol. Relative atomic masses: C=12.0\text{C} = 12.0C=12.0, O=16.0\text{O} = 16.0O=16.0)
