What are some pollutants from fuels?
Carbon monoxide Carbon dioxide Sulfur dioxide Nitrogen oxides Soot particles
What’s global warming?
A dramatic increase in global temperatures.
What’s acid rain?
Acid rain prevents trees to grow. It is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air.
What are catalytic converters?
They help to speed up reactions and they reduce the release of toxic gases from the exhaust pipe in cars.
