  1. Draw and label a Helium atom (include labels for electrons and neutrons) Rocks and Metals Rocks and Building Match to the correct explanation about the iron extraction process Haematite -Helps remove impurities in the iron Coke -is made from coal. Acts as a reducing agent. Blast Furnace -Is the most common iron ore Limestone -What we extract iron in Complete the paragraph: Limestone is mostly made of………carbonate (whose chemical formula is ……….)As well as being used to produce building material. Limesstone can be used to produce…………. , …………… and …………. That can be also used in building. What does thermal decomposition mean? Complete the general formula for the decomposition of carbonates: ____________  _________ + __________ Another name for slaked lime is….. Another name for quick limes is List some properties for each of these building materials: Cement Concrete Glass What is an alloy? Give 2 examples of alloys and where we might use them The Big C1a Summary Quiz effects Crude oil is a mixture/compound (delete as appropriate) Burning Fuels Draw propane Write its chemical formula: The longer the hydrocarbon chain the: (delete as appropriate) Higher/lower boiling point More/less volatile More/less viscosity More/less flammable Causes Solutions…..

  2. Crude oil is derived from ancient biomass found in rocks. Many useful materials can be produced from crude oil. Some of these are burnt as fuels. Evaluate the impact on the environment of burning hydrocarbon fuels and the social economic and environmental impact of uses of fuels.

  3. Emulsions are commonly used in many foods. Evaluate the use, benefits, drawbacks and risks of using emulsifiers in foods.

  4. Olives grow in some parts of the world. They are a good source of oil. This olive oil is used in cooking , it is eaten as a food and can be used as a fuel. Write about why olives can be used in this way.

  5. Polymers are a very important type of substance in todays society. However, many people are worried about how to dispose of them. Explain why disposing of polymers is a particular problem.

  6. Most of the iron we use is converted into steels. Describe and explain how the differences in the properties of the three main types of steel allow them to be used in different ways.

  7. Describe and explain how the fractions are separated in a fractionating column.

  8. The atmosphere of the Earth today contains about 21% oxygen, 78% nitrogen and 1% other gasses. Describe how the early atmosphere may have been different to todays atmosphere.

  9. Metal carbonates, such as limestone decompose into carbon dioxide when heated. Some carbonates decompose at a higher temperature. Describe an experiment to find out which of the two carbonates decomposes at the highest temperature.

  10. Each year billions of plastic bags are given free to shoppers. These bags are made from poly(ethane) and are often used only once. After being used many of these plastic bags are either thrown away as litter or buried in landfill sites. Describe the advantages and disadvantages of using plastic shopping bags made from poly (ethene).

  11. In Brazil, ethanol has been used as a vehicle fuel from many years. Ethanol can be produced by the fermentation of plant sugars, such as those in sugar cane. It can also be produced from ethane gas. Ethene is made from crude oil. Outline the advantages and disadvantages of producing ethanol from plant crops, compared to producing ethanol from ethane.

  12. Many drinks cans are made of aluminium. In 2008, people in Germany recycled 96% of their aluminium cans while just 51% of British aluminium cans were recycled. The rest were buried in landfill sites. Give reasons why Britain should increase the percentage of aluminium cans it recycles.

  13. Iron ore is an important resource is it quarried in some parts of the UK. Evaluate the social, economic and environmental impacts of quarrying for Iron ore. 

  14. Many plants produce useful oils that can be converted into consumer products including processed foods. Explain the advantages and disadvantages of using vegetable oils in food and the impacts on diet and health. 

  15. Wegener’s theory of crustal movement (continental drift) was not generally excepted for many years. Outline the conflicting theories and explain why Wegener was not accepted at the time.
