A car using fuel X produces the following masses of pollutants when 1 kg of fuel is burnt:
- carbon monoxide: 50 g
- oxides of nitrogen: 40 g
- sulfur dioxide: 5 g
- unburnt hydrocarbons: 15 g
Which statement can be inferred from this data?
- carbon monoxide: 50 g
- oxides of nitrogen: 40 g
- sulfur dioxide: 5 g
- unburnt hydrocarbons: 15 g
Which statement can be inferred from this data?
- Carbon monoxide from fuel X is the main cause of acid rain.
- Unburnt hydrocarbons from fuel X are the only cause of global warming.
- Sulfur dioxide and oxides of nitrogen from fuel X can contribute to acid rain.
- The data prove that fuel X engines run at a lower temperature than other engines.
