Air pollutants
Chemistry · Secondary 4 · Hard · Air pollutants
A student burns 1.0 kg of fuel M and 1.0 kg of fuel N in separate engines. The masses of pollutants in the exhaust gases are shown.
- Fuel M: 50 g carbon monoxide, 20 g oxides of nitrogen, 3 g sulfur dioxide
- Fuel N: 20 g carbon monoxide, 20 g oxides of nitrogen, 3 g sulfur dioxide
Which statement can be inferred from this data?
- Fuel M: 50 g carbon monoxide, 20 g oxides of nitrogen, 3 g sulfur dioxide
- Fuel N: 20 g carbon monoxide, 20 g oxides of nitrogen, 3 g sulfur dioxide
Which statement can be inferred from this data?
- Fuel M produces more carbon monoxide per kilogram of fuel than fuel N.
- Burning fuel M produces more acid rain pollutants than burning fuel N.
- Fuel N contains a higher percentage by mass of sulfur than fuel M.
- The combustion temperature in the engine using fuel N is higher than that using fuel M.
