2 For more awesome GSE and level resources, visit us at 1 Which statement about is not correct? It is a greenhouse gas. It is an alkene. It is formed by decomposition of vegetation. It is used as a fuel. 2 Which process does not produce? complete combustion of a fossil fuel fermentation reaction of an alkali with a carbonate respiration 3 arbon dioxide and both contribute to climate change. Which process produces both gases? complete combustion of natural gas farming cattle heating calcium carbonate respiration

Which gas is likely to be present in a higher percentage inside the bin than in the air outside the bin? oxygen sulfur dioxide 5 arbon dioxide and are greenhouse gases which contribute to global warming. Which process does not increase global warming? burning fossil fuels decay of organic waste farming cattle for beef growing crops such as sugar cane 6 These statements are about a gas It is produced by thermal decomposition of a carbonate. It is produced by the fermentation of glucose. It makes up 1% of unpolluted air. It is produced during the production of steel from iron. Which statements are correct for? 1 and 2 only 1, 2 and 3 1, 2 and 4 1, 3 and 4

Gas Z is formed when gas X is burnt with an excess of oxygen. What are X, Y and Z? X Y Z 8 The list gives four experiments carried out with calcium carbonate acid added alkali added heated strongly water added Which experiments produce? 1 and 2 1 and 3 2 and 3 2 and 4

5 For more awesome GSE and level resources, visit us at 9 Which statement about is not correct? It is a liquid produced by distilling petroleum. It is produced as vegetation decomposes. It is produced by animals, such as cows. It is used as a fuel. 10 Which pollutant gas is produced by the decomposition of vegetation? nitrogen oxide sulfur dioxide 11 In which process is not formed? burning of natural gas fermentation heating lime respiration 12 Which information about and is correct? formed when vegetation decomposes key greenhouse gas = true present in unpolluted air = false produced during respiration

Gas Y is formed when gas X is burnt with a small amount of oxygen. Gas Z is formed when gas X is burnt with an excess of oxygen. What are X, Y and Z? X Y Z

Which process does not increase global warming? burning fossil fuels decay of organic waste farming cattle for beef growing crops such as sugar cane 17 The table gives the composition of the atmosphere of four newly discovered planets. planet W X Y Z composition of atmosphere argon, and oxygen argon, nitrogen and oxygen argon, and, nitrogen and oxygen On which planets is the greenhouse effect likely to occur? W only W, X and Z W and Y only W, Y and Z

Two of these gases are emitted into the atmosphere as a result of processes within animals. Gas 1 is produced by process 3. Gas 2 is produced by process 4. Which words correctly complete gaps 1, 2, 3 and 4? 19 newspaper article claims that is formed as follows during respiration when calcium carbonate reacts with hydrochloric acid when burns in air Which statements are correct? 1, 2 and 3 1 and 2 only 1 and 3 only 2 and 3 only
