    Chemistry Paper 61

    Either that, or it wasn't even near 70 degrees, and further heating would increase the rate.. Who knows! And honestly, it's one mark so who cares . Hopefully they'll accept both x) (Check your inbox btw >.>)

    Chemistry Paper 61

    It's not that hard to understand how HEATING would speed up rate of reaction. Sure they provided you with hot water, but was a temperature specified ... no? Over time the solution would cool, causing a decrease in the rate. IF we apply heat constantly throughout the experiment, the temperature...

    Im not saying stirring is wrong, I'm just saying heating isn't wrong. It could be accepted.

    Chemistry Paper 61

    If you heat water up till say 90 degrees and leave it, it won't stay 90 degrees. It will begin to drop.. SO heating is an acceptable answer as it keeps the temperature increasing as a constant rate -> Increase in kinetic energy -> Increase in collisons -> Increase in rate x)

    Is this a test for sulphates? Because in a test for halides, barium chloride would only form a white precipitate if nitric acid was added.. but we added sulfuric acid, not sure what test that is :S

    Yeah there is sulfuric acid, but you said nitric acid.. where does the nitric acid come from? :S

    There is no dilute nitric acid, its hydrochloric acid..

    Yeah same, as long as you didn't lose 15 marks.. An A* is till possible. (I lost around 8-10 marks :S)

    Got another question.. Paper:http://www.xtremepapers.com/papers/CIE/Cambridge%20IGCSE/Chemistry%20(0620)/0620_s09_qp_6.pdf Q1)c) I know that crystals can form by heating till crystallisation point, but since it's 2 marks the mark scheme also says using a glass rod? How the hell do crystals...
