C1-8 Combustion & air pollution

What does oxidation mean?

• Addition of oxygen

• Oxygen is present

• Loss of oxygen

• Oxygen is needed for the reaction

When hydrocarbons are burnt in oxygen what is produced in the reaction?

• Carbon dioxide and hydrogen

• Sulphur trioxide and ammonia

• Sulphur dioxide and hydrogen

• carbon dioxide and water

What are the production products from incomplete combustion?

• carbon monoxide and carbon hydroxide

• carbon particulates and carbon dioxide

• carbon monoxide and carbon dioxide

• carbon particulates and carbon monoxide

Some fossil fuels such as coal contain sulphur impurities. When this is burnt (in power stations) this means that the sulphur is oxidised to sulphur dioxide. What problems does this pollutant cause?

• Acid rain

• Global dimming

• Global warming

• Denitrification

Some fossil fuels such as coal contain sulphur impurities. When these fuels are burnt the sulphur is oxidised to sulphur dioxide which causes acid rain. The formula for sulphur dioxide is...

Carbon monoxide can combine with hemoglobin in red blood cells and prevent the blood for m carrying oxygen. The formula of carbon monoxide is (a)  

Carbon monoxide can combine with hemoglobin in red blood cells and prevent the blood for m carrying oxygen. Carbon monoxide is formed from which type of combustion?

• Complete

• Incomplete

• Thermal

• Decomposition

During incomplete combustion tiny particles of carbon can be released into the atmosphere. These tiny particles are responsible for a phenomenon known as global ...
