    no delocalised electrons in the water question
    I think the answer is no free ions not electrons

    That's what I wrote too because even if heat is lost, a digital thermometer which can detect small changes in temp will still not show the true value.
    i wrote use a scale to measure the magnesium strip, becuause its accurate in measuring, lol is that correct?

    And also a half equation question (can't remember the question number) to which I think the answer was 2Cl- ---> cl2 + 2e (or something like that)

    That's more of a control variable I think. What did you write for changing temp. to 5 degrees? I said place flask in a cold water bath.

    Is this in C2 there is no any question asking u to draw this
    (Original post by Benb2000)
    What question are you on about here?
    This was c3. But even though would i get the 4 marks? I didnt draw a curved diagram and on a past mark scheme it says 1 mark for reaction pathway curve correctly drawn. ??

    What did people put for this equation question: ___Cl- arrow👉🏻 Cl2 +____

    Does it matter that i said ''the amount of hydrochloric acid'' instead of the ''volume'' ? Also, i wrote for question 1d about changing apparatus that they could use a thermometer with smaller intervals to make it more accurate. I was about to write ''use an electric thermometer'' but then went against it. Think I'll get the marks?

    i put 2CL- > Cl2 + 2e-

    Not sure if it's right tho..

    the answer is no ions. Completely purifying water means the ions are removed so it can't conduct electricity.

    <<< says the internet. I wrote no delocalised electrons.

    Thats right because your gaining 2 electrons altogether.

    Could you say the solution was cloudy because the two chemicals were mixed together?
