Chemistry C1 4.3 Burning fuels. 0.0 / 5 ? ChemistryCrude oil, cracking and hydrocarbonsGCSEAQA Created by: Atlanta and JacobCreated on: 10-04-16 18:31 What does burning pure hydrocarbons in plenty of air produce? They are oxidised to carbon dioxide and water, however the fuels we use are not always burned completely and also contain other substances. 1 of 13 What might burning hydrocarbons in a limited supply of air produce? An incomplete combustion which may produce carbon monoxide and solid particles. 2 of 13 What do any sulfur compounds in the fuel burn to produce? Sulfur dioxide. 3 of 13 What can be formed when fuels burn under extreme conditions? Oxides of nitrogen. 4 of 13 What are the solid particles that may be produced due to incomplete combustion? Soot (carbon) and unburnt hydrocarbons called particulates. 5 of 13 Most fossil fuels contain sulfur compounds, what is produced when these are burned? Sulfur dioxide. 6 of 13 What does sulfur dioxide cause? Acid rain. 7 of 13 What might oxygen and nitrogen in the air combine to form when fuels burn at high temperature? Nitrogen oxides. 8 of 13 What does nitrogen oxides form? Acid rain. 9 of 13 What is the word equation for the complete combustion of ethane? Ethane + oxygen (arrow symbol) carbon dioxide + water. 10 of 13 What are possible products of the incomplete combustion of a hydrocarbon? Carbon monoxide, carbon, unburnt hydrocarbon, water. 11 of 13 What environmental problem is caused by sulfur dioxide and nitrogen oxides? Acid rain. 12 of 13 **YOU SHOULD BE ABLE TO WRITE BALANCED SYMBOL EQUATIONS FOR THE COMPLETE AND INCOMPLETE COMBUSTION OF A HYDROCARBON WHEN GIVEN ITS FORMULA** ** 13 of 13
