Why is crude oil separated into fractions?
To make useful fuels/products
1 of 8
Name the products when ethane, burns completely
Carbon dioxide and water
2 of 8
Give 3 reasons why fractions with lower boiling points are more useful as fuels
They burn more easily, thin runny liquids, burn with little smoke
3 of 8
Name 2 fuels that can be made from renewable sources
biodiesel, ethanol, hydrogen
4 of 8
Some exhaust fumes contain particulates. What are particulates and how are they produced?
solid soot/ carbon and unburnt fuel, produced by incomplete combustion
5 of 8
Explain why burning some fuels produce sulphur dioxide
The fuel contains sulphur (compounds) these burn to produce sulphur dioxide
6 of 8
Propane is used as a fuel for cookers, explain why propane should always be burned in a plentiful supply of air
poisonous gas carbon monoxide may be produced in limited supply of of air
7 of 8
Why are some scientist concerned about the carbon dioxide produced by burning fossil fuels
The carbon was locked up in fossil fuels; increases carbon d in atmosphere; carbon d is a greenhouse gas; may cause global warming
