(a)
Interpretation:
Why does burning coal produce sulfur dioxide has to be determined. Another source of
Concept Introduction:
A fuel is a substance which releases energy in the form of heat while undergoing combustion. Hydrocarbons which have high heats of combustion make it a best fuel.
The general equation for the complete combustion of a hydrocarbon is written below,
Coal is a good fuel becouse it is completely made up of carbon atoms. It is a fossil fuel.
Coals can be classified and graded according to the carbon percent and the impurity percent such as sulfur.
Anthracite coal has high carbon content.
(b)
Interpretation:
Why does burning coal produce nitrogen monoxide has to be determined. Another source of
Concept Introduction:
Heat of combustion: It is also known as potential heat of fuel. Heat of combustion of carbon depends on its allotropic form.
A fuel is a substance which releases energy in the form of heat while undergoing combustion. Hydrocarbons which have high heats of combustion make it a best fuel.
Coal is a good fuel becouse it is completely made up of carbon atoms. It is a fossil fuel.
