    It wasn't that hard,Just different so the grade boundaries should be 30-35

    How so?
    1.65/32=Ans 1
    Change=Energy/Ans 1=Ans 2
    Yh that what I did, but what did u get for heat capacity change thing, I mean what did u use for water mass?

    What did you guys wrtie in that question in which we had to convert G TO F?
    I wrote that reagent = potassium hydroxide
    Condition = alcoholic

    The reagent is alcoholic potassium hydroxide, but the condition I think is heating. Not too sure about the condition.

    I wrote Potassium dichromate and sulphuric acid for reagent and Reflux for condition

    Uhh the mass of water? I used Something + water=idk what value(lets called this X)
    Something=Y
    So i did X-Y=Mass of water.
    I think I got the enery change 27### joules I don't remember the last 3 digits

    I wrote something really stupid.

    But the actual answer is cobalt chloride paper which changes from blue to pink.
    Or it puts out a lighted splint.

    Actually you had to convert a halogenoalkane to an ALKENE so potassium hydroxide in alcoholic cond will be used. This is not OXIDATION I'm afraid.

    You could also use anhydrous copper (ii) sulphate right?
