A ceramics workshop compares the gaseous pollutants released by two fuels used in a kiln. Both fuels contain carbon and hydrogen. Fuel S also contains sulfur as an impurity.
In each test, 1.00 kg of fuel was burned.
| Test | Fuel | Oxygen supply | Mass of pollutant P released in g | Mass of pollutant Q released in g |
|---|---|---|---|---|
| 1 | R | Plentiful | 0.0 | 0.0 |
| 2 | S | Plentiful | 4.0 | 0.0 |
| 3 | S | Limited | 3.8 | 26.0 |
Explain which gaseous pollutant is P and which gaseous pollutant is Q. Use the results in the table.
