Got my midterms in a few days. Everything is going well except Chemistry P5. I got a horrible teacher for that and haven't learned anything all term. Any suggestions as to how I should study for it? What do I need to know?

I'll be talking about question 2 since that's what my teachers have taught us so far from P2
I'd say ,practice the way u do ur graphs ,that is choose the best scale and fill the tables in least time possible .
U should try to figure out what caused the anamoulous point .It will be different in each experiment but it's typical like . It was heated for too long in decomposition or it did not decompose completely etc .
Now sometimes there is a relation given in the question which u will prove by using ur gradient . Remember ,be it P5 of chem or Physics,ur marks lie on how accurately u have plot the points and drawn the line . U will draw the right angled triangle when u choose the two points on the graph for slope .
Now since it's chemistry,there are alot of chances that graph could be a curve so incase of that when u have to find the gradient , u will notice that the first 20% of the graph is infact a straight line and u will use that for slope . This is not the case everytime and u will have to keep ur eye on it .
If u have anymore questions regarding question 2 of P5 ,feel free to ask
