Coal is used as a fuel in power stations.
The table shows the percentage of carbon and sulfur in four different coal samples.
Sample Percentage (%) by mass in coal
Carbon Sulfur
A 22.1 0.4
B 46.8 0.6
C 66.3 0.9
D 92.0 0.7
plz help me to answer any question you can:
a) Sulfur produces a gas that causes acid rain.
Name the gas.
b) Give one environmental effect caused by acid rain.
c) Which coal sample produces the most acid rain from 1 kg of coal?
Use the table above.
Give a reason for your answer.
Sample
Reason
d) Calculate the mass of coal sample A that would produce the same amount
of carbon dioxide as 1 kg of coal sample C.
Mass of coal sample A = kg
e) Incomplete combustion of coal can produce carbon monoxide.
Carbon monoxide is a toxic gas.
Give two reasons why people may be unaware of the presence of carbon
monoxide.
