    For the six marker I put 2.3g of zinc is equivalent to 0.036 moles and a solution of 0.7 moles per dm3 with a volume of 50 cm3 has 0.035 moles so it leveled off because additional copper sulfate would not react with the zinc as all the zinc would have run out.

    There was one question, I think it was on C3 but i may be wrong, and it was a gap fill with 2 spaces, the first was on about moles and i put grams, the second was about comparing elements and i put carbon 12, i was wondering what other people put for this.
    yes i put carbon 12 too.

    I put conc and volume of cylinder. Im sure about the conc but not about the cylinder. How could it be mass? If the surface area is going to be changed then surely you can't keep the mass the same as well because to increase the surface area you make the chips smaller and so the mass will decrease when it's smaller
    No, I am pretty sure that when you increase the surface area it doesn't decrease the mass because you are (in a way) cutting the "thing" in to smaller pieces so it is the same mass because you are not taking anything away but the surface area increase because there is more "edge". I don't know id that make sense.

    Tbf I did think that in the exam, but in th end went for mass and conc

    Yeh I understand but why would mass change the rate of reaction in the first place.

    Exactly, which is why it didn't look like a good option.
