A ceramics furnace burns a carbon-containing fuel with sulfur as an impurity.
An engineer burns 150 g of the fuel for 10 minutes using each of two burner settings.
| Burner setting | Volume of air supplied in 10 minutes in dm³ | Energy released in MJ | Mass of black solid collected in g |
|---|---|---|---|
| P | 2400 | 7.2 | 0.04 |
| Q | 1500 | 5.6 | 1.80 |
Using all the data, explain which burner setting is expected to produce more carbon monoxide.
The exhaust gases from the furnace are released through a chimney.
Give the pollutant formed from the sulfur impurity and one environmental effect of this pollutant.
