Carbon Chemistry C1b 0.0 / 5 ? ChemistryFuelsGCSEOCR Created by: gillian1132Created on: 21-02-17 19:06 Which key factors need to be considered whilst choosing a fuel? Energy value, Cost, Toxicity,Pollution caused, Availability,Storage and Ease of Use 1 of 8 Why is the amount of fossil fuels burnt increasing? It's due to the increasing world population and it's growth of use in developing countries such as India and China 2 of 8 What happens when a hydrocarbon is combusted? Water and Carbon dioxide is made 3 of 8 By experiment, how can you prove that the combustion of hydrocarbons produces carbon dioxide and water? You would use a candle, a beaker full of cold water with cobalt chloride paper inside an air pump, and a conical flask with limewater 4 of 8 What should happen if water and CO2 are produced during this experiment? The blue colbalt chloride paper should turn pink and the limewater should go cloudy if there's carbon dioxide 5 of 8 What is complete combustion and what is the word equation? When a fuel burns in plenty of oxygen, Fuel+Oxygen>Carbon Dioxide +Water 6 of 8 What is incomplete combustion and what is the word equation? When a fuel burns and there's not enough oxygen, Fuel+Oxygen>Carbon Monoxide +Water 7 of 8 What are the advantages of complete combustion over incomplete combustion? That more energy is released 8 of 8
