3. Give the formula
Carbon dioxide
4. Give the formula
Sulphuric acid
5. Give the formula
Calcium chloride
6. Which are solids?•Hydrogen chloride
•Sulfuric acid
•Nitric acid
•Ethanoic acid
•Tartaric acid
•Citric acid
7. What is an indicator?8. What is neutralisation?9. What does this mean?
10. Acid + metal ? + ?11. Acid + metal oxide ? + ?
12. Acid + metal hydroxide ? + ?13. Acid + metal carbonate ? + ? + ?
14. What’s the salt?
Sulfuric acid Magnesium
15. What’s the salt?
Nitric acid Copper oxide
16. Name the apparatus
17. 4 ways to speed up a reaction ..
18. Why does a reaction go faster when the acid is more
concentrated?• Particles
• crowded
• collisions
• frequent
19. What do you know about catalysts?
20. What does this tell you?
Time (min)
Mass lost (g)
20oC
10oC
21. Why are rates important in industry?
22. Which is the relative atomic mass?
12
C
6
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 CO2.
24.The recipe bit …What mass of ammonia is produced from 14g of nitrogen?
N2 + 3H2 2NH3 Underline
Molecules in
x relative formula mass
Same at both sides
Keep the same units!
25. Percentage yield
You expected 100 tonnes of ammonium sulphate but the actual mass was 25 tonnes.
What was the % yield?
Good luck!
