Incomplete combustion can lead to the formation of small particles of carbon, which are called 'particulates', or 'soot'.
Which two of the following describe the adverse effects of these particulates?
Cause acid rain as it dissolves in rainwater
Forms clouds of smog which reflect light back to space
Cause respiratory problems as the particles damage our lungs
Reduces haemoglobin's ability to transport oxygen
|
Which two products are formed by the incomplete combustion of hydrocarbons?
Particulates
Carbon monoxide
Sulfur dioxide
Nitrogen oxides
|
Describe why carbon monoxide is harmful for humans.
|
When burning fossil fuels, how is sulfur dioxide formed?
Sulfur is one of the main elements in fossil fuels as is oxidised like carbon and hydrogen
Sulfur from the air is oxidised at the high temperature of the engine
Sulfur is an impurity in some fossil fuels and is oxidised when they're combusted
|
When burning fossil fuels in an engine, how are nitrogen oxides formed?
Nitrogen is one of the main elements in fossil fuels, and is oxidised like carbon and hydrogen
Nitrogen from the air is oxidised at the high temperature inside the engine
Nitrogen is an impurity in some fossil fuels, and is oxidised when the fuels combust
|
Which of the following can form acid rain?
(Select all that apply)
Carbon monoxide
Nitrogen oxides
Sulfur dioxide
Particulates
|
Which of the following are adverse effects of acid rain?
(Select all that apply)
It binds our haemoglobin and reduces the amount of oxygen it can transport
It makes the soil more acidic, which harms plants
It forms smog which contributes to global dimming
It damages certain buildings and statues
|
Other than acid rain, what problem is caused by sulfur dioxide and oxides of nitrogen?
Global warming
Global dimming
Respiratory problems in humans
