4. 3. Give the formula Carbon dioxide

5. 4. Give the formula Sulphuric acid

6. 5. Give the formula Calcium chloride

7. 6. Which are solids? Hydrogen chloride Sulfuric acid Nitric acid Ethanoic acid Tartaric acid Citric acid

8. 7. What is an indicator? 8. What is neutralisation? 9. What does this mean?

9. 10. Acid + metal  ? + ? 11. Acid + metal oxide  ? + ? 12. Acid + metal hydroxide  ? + ? 13. Acid + metal carbonate  ? + ? + ?

10. 14. What’s the salt? Sulfuric acid Magnesium

11. 15. What’s the salt? Nitric acid Copper oxide

12. 16. Name the apparatus

13. 17. 4 ways to speed up a reaction..

14. 18. Why does a reaction go faster when the acid is more concentrated? Particles crowded collisions frequent

15. 19. What do you know about catalysts?

16. 20. What does this tell you? Time (min) Mass lost (g) 20 o C 10 o C

17. 21. Why are rates important in industry?

18. 22. Which is the relative atomic mass? 12 C 6

19. 23. Relative formula mass. This tells you the number of times a molecule is heavier than an atom of hydrogen E.g. Work out the Mr of CO 2.

20. 24.The recipe bit … What mass of ammonia is produced from 14g of nitrogen? N 2 + 3H 2  2NH 3 Underline Molecules in x relative formula mass Same at both sides Keep the same units!

21. 25. Percentage yield You expected 100 tonnes of ammonium sulphate but the actual mass was 25 tonnes. What was the % yield?

22. Good luck!
