      Yes it is worth learning them particularly

      - Starch in plants by photosynthesis

      - Prepare a sample of oxygen gas

      - Prepare a sample of carbon dioxide gas

      It shows the mark for each question on your exam? I will create a paper consisting of experiment questions only if you want.

      yeah ino it shows the marks but overall is it a massive loss if you didnt do them

      Not a massive loss but it could be easy marks awarded if you know the experiments.

      The major experiment question usually take up 9% of the exam, you can still get an A without them but I'd advise you to have a simple knowledge of them

      Exactly the ones Sarah said. If you give me your email, I will send you a picture of them all (WITH the actual chemical equations).

      But I think she meant Sodium Hydroxide (Titration) instead of Sodium Chloride
