Introduction
The human population is growing very quickly and many people argue that humans are using up the Earth's resources at an unsustainable rate. All of the resources we use come from the groun and the atmosphere. In this unit we will look at how we can extract useful metals from the ground and why it is important that we recycle as much of our rubish as possible.

Task 3: Displacement reactions
Task 3: Displacement reactions
Task 3a: Read through the slides and watch the videos
Define displacement reaction
Write the word equations for both reactions in the videos, using slides 12 and 14 to help.
Explain what a displacement reaction is and why it occurs
Suggest why some displacement reactions occur more easily than others
Task 3c: Write a word equation to show the displacement reaction between:
Iron Sulphate and Magnesium
Copper Sulphate and Magnesium
Task 3d: Predict whether a displacement reaction will occur. Write word equations to show the displacement reactions :
Gold + Copper Sulphate →
Magnesium + Sodium Chloride →
Potassium + Copper Sulphate →
Zinc + Copper Sulphate →
Iron + Potassium Chloride →
Zinc + Hydrochloric Acid →

Task 4c: Make notes that:
Explain why gold was one of the first metals discovered
Describe what we mean when we say metals can be 'found native'
Annotate your reactivity series to show which metals are found native.
Define ore.
Explain how metals less reactive than carbon can be extracted from thier ores
