10. IT: Which?

11. CFCs CFCs in the atmosphere are known to deplete the ozone layer.
They are a group of man-made chemicals that were first produced in the first half of the twentieth century.
CFCs usage includes as coolants in refrigeration systems and air conditioners, as solvents to clean electronic components and in the manufacture of plastic foam.
Countries are now trying to limit the production of CFCs because of their adverse effect upon the ozone layer.
Even though worldwide production of CFCs has decreased, because the CFCs remain active in the atmosphere for many years it is expected that the ozone layer will only recover by the middle of the twenty first century.

13. Copper & Silver
Above you can see some copper powder that has just been added to silver nitrate solution. When copper is added to a solution of silver nitrate, copper will displace the silver from the solution.

21. Chemical Changes
In chemical changes a new substance is made and the change is hard to reverse.
Examples of chemical changes?
Making glass
Burning coal
Rusting

Boiling an egg
Baking a cake
Is eating food a physical or chemical change? Discuss!

22. Diffusion

We can use potassium permanganate crystals added to water to study diffusion.

23. What factors affect the rate of a reaction?
higher concentration
lower concentration
Image copyright JSH Education Ltd
If you increase the concentration of the reactants, there is more chance of the particles colliding so the rate of reaction increases.

24. Gravity causes the sand particles to settle to the base of the beaker.
