Coz the two chem threads were locked yesterday, and still hvnt been opened, i just made a new thread
So is a suction pump the same thing as a pippete filler?
What was the answer to the last part of the graph question? o.o
could be 65-70. depending on your graph readingyeah, it's the same thing
okay cool. And what about the heating apparatus thingy? Did we have to mention the water bath, or a bunsen burner, wire guaze and tripod stand? :/
water bath --> alcohol is flammable so can't use any of them.
Water bath and electric heater were the only two correct answers. At least in previous mark schemes this has been the rule. Bunsen burner is by all means incorrect.
speed of reaction's answer was D .I can picture the examiner report for the last question: 'This was by far the least correctly attempted questions, with very few candidates producing correct answers.'
LOL
Anyways I got it wrong. I made very silly mistakes which will cost me like 4-6 marks
-There was one with test tubes for which answer was I and IV,
-Barium sulphate is insoluble so filter, rinse, dry in folds of filter paper,
-For the speed of reaction graph the third option in the bullet list was the fastest, the second was less fast with same moles and the first bullet was the slowest with least moles (lowest constant line).
-Mr was supposed to be 39. I made an error before this question for which i will lose one mark.
-No answers were to be rounded at any point apart from the last step btw
-I wrote KMnO4 as the agent and purple to colourless for it.
Yeah thats all i can remember for now xD
Yeah i don't remember the options. I just remember that there were two with greater moles (when you apply the formula), and one with different, which was less in moles. From the two greatest, I think it was 50 cm3 that turned out to be the fastest, but I don't recall the figures/choices, Just the technique.

correct.
im afraid, then you get 0
Relative molecular mass is always supposed to be in whole number. Chlorine is an exception.
True, let me look at some mark schemes.
oh....
