    It did say in the question "write the equation"
    Yeah I did but I didn't include state symbols, which it did not explicitly ask for

    Oh, no, just state that silver is solid and that it blocks light slightly.

    It said "alkaline fuel cell breathalyser". The one in the book is the acidic one which uses platinum.
    Alkaline fuel cells use graphite electrodes.

    do you know if thats actually correct , cuz a few sites on the internet are saying its carbon???????????
    Platinum for sure

    GrandMasti C0balt do you guys reckon if for the polychromatic glasses thing it matters if you didin't put state symbols but mentioned in your answer that Ag+ ions are reduced into solid silver atoms?
    I didn't mention state symbols I don't think kit matters,

    That's a different fuel cell.
    Btw, the question was about Alkaline Fuel Cell breathalyser wasn't it? I can't remember the question now, if it was a hydrogen, oxygen cell then it must be platinum

    I gotta say that the synthesis question was a nice 5 marker

    1) firstly acidified dichromate + reflux (full oxidation)
    2) PCl5 to form the acyl chloride (I named it as Benzoyl chloride)
    3) Finally NH3 to form the benzamide and hcl

    Nah it was zwitterion. Amphoteric is only used for complex ions.

    Breaaathe.
    Phew.

    I'm trying but I'm resitting, it's my last chance, and here I am just dropping marks everywhere.

    How did you find it?

    I can't remember the question, but if it was just gasses like O2 and H2 then it should be platinum. If it was an alcohol, alkaline cell it should be graphite.

    Can anybody's school email Edexcel about the cisplatin [CuCl4]2- question. [CuCl4] 2- is supposed to be tetrahedral but they said it was the same shape as cisplatin which is square planar.

    yeah that was a weird one... I drew it as square planar though since it said that it was the same shape
