level questions: Combustible fuels and pollution

QuestionAnswer
Burning fuels can release gases like sulfur dioxide and oxides of nitrogen, which contribute to pollution.Polluting Gases from Burning Fuels
What are some of the gases released when fuels are burned?Polluting gases like sulfur dioxide and oxides of nitrogen are released when fuels are burned.
Some fuels contain impurities, such as sulfur.Fuels with Impurities
What is a factor contributing to the release of polluting gases during fuel combustion?Fuels with impurities, like sulfur, contribute to the release of polluting gases during combustion.
Sulfur in fuel reacts with oxygen in the air during combustion, forming sulfur dioxide gas.Sulfur Reaction in Fuel
How does sulfur in fuel contribute to air pollution during burning?Sulfur in fuel reacts with oxygen in the air, producing sulfur dioxide gas.
Oxygen and nitrogen in the air react in the high temperatures of vehicle engines, producing nitrogen oxides.Formation of Nitrogen Oxides
What reaction occurs in vehicle engines that results in the formation of nitrogen oxides?Oxygen and nitrogen in the air react in the high temperatures of vehicle engines, producing nitrogen oxides.
Sulfur dioxide and nitrogen oxides, when dissolved in rainwater, lead to the formation of acid rain.Acid Rain Formation
What gases contribute to the formation of acid rain when dissolved in rainwater?Sulfur dioxide and nitrogen oxides contribute to the formation of acid rain when dissolved in rainwater.
Sulfur dioxide and nitrogen oxides can cause respiratory problems in humans.Respiratory Problems from Sulfur Dioxide and Nitrogen Oxides
What health issues can result from exposure to sulfur dioxide and nitrogen oxides?Respiratory problems in humans can result from exposure to sulfur dioxide and nitrogen oxides.
