Chemistry Chapter 10 – Sustainable development – Earth’s resources, potable water and waste water treatment Describe how we can make ways of our life sustainable. State the 3 main stages in water treatment and the purpose of it. Describe what is meant by the water footprint. Describe the processes involved I sewage treatment and where the waste water comes from. Define the term finite resource and renewable. Give examples. Describe how we can get potable water from seawater. Define the term potable water and state where we can obtain potable water form.

Chemistry Chapter 10 – Sustainable development – life cycle assessment, alternative metal extraction and reducing use of resources State what an LCA is. Give an example of either plastic or paper as an LCA. You must reference all the stages. HIGHER TIER – describe the process of phytomining. Include advantages and disadvantages. What stages are included in LCA’s. HIGHER TIER – describe the process of bioleaching. Include advantages and disadvantages. Explain why we need to look at ways of reducing finite resources and recycling and reusing materials.

Chemistry Chapter 10 – Sustainable development– RP and maths State how we should draw a graph. Include reference to line of best fit. Hint – are they always a straight line? Independent variable – Dependent variable – Control variables – Describe a method used to investigate and analusise the purification of water samples from different sources. Include a diagram of your set up. Write a risk assessment for this practical. Include the risk, hazard and control for at least 1 risk. When looking at a graph or pie chart describe what information you are able to get from them and where you would find this information. Use the example pie chart for support. State what results you would expect to see. Explain why it is important the watch glass is reheated and dried before it is reweighed?
