is it worth knowing the experiments or am i wasting time looking over them ? are they a big percentage of the marks and if i should know them any ones the always come up?
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.
Not a massive loss but it could be easy marks awarded if you know the experiments.
Chemical equations for
zinc +hydrochloric acid
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
What's the one for sodium chloride??
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
Yeh I did xx
