    Well, here it's slightly different isnt it? And wiki is with us too, let's keep our fingers crossed and hope for the best :)

    GT for Chemistry paper 22 AS.

    guyz check this http://en.wikipedia.org/wiki/Flame_test it says phosphorous has a blue-green flame, does that count? what if i didnt write sodium and wrote P instead

    Did they ask "burns with coloured flame IN chlorine" or did they ask about the chloride of the element burning with a coloured flame?

    Nope. Im just scared they can understand my handwriting in paper 5, coz i REAALLY rushed a lot.

    Still can't be sure bro, coz the STRUCTURAL was in bold. I mean why would they stress on that if displayed is acceptable? Anyway, Im dead sure you won't lose all the 6. :)

    Chemistry Paper 2

    Ahan, Im darn confused about that. What I drew was one -COOH group to ester group and the other remains. This is what wiki says " It hydrolyzes, producing maleic acid, cis-HOOC–CH=CH–COOH. With alcohols, the half-ester is generated, e.g., cis-HOOC–CH=CH–COOCH3." ^BIG RELIEF ! By it, they...

    The organic question, maleic acid and alcohol esterificaction?

    Do both the -COOH groups get converted to ester? Or just one of them?

    I just checked the w11 gt, and turns out you need atleast around 200/270 if you want an A* in chemistry (5 papers). So try n not lose more than 50 marks in total to be on the safe side.

    Dude, this is from a past paper. There are 3 points complete octet, high activation energy and inert. It was just 1 mark right? I wrote all the 3 points, bleh..

    Chem p22

    ^^ Are you sure it's -129? Coz i'm pretty sure it's +129. Confirmed it with my friends too

    Chem p22

    I too think it was +129, but the reasoning is incorrect. Combustion is always exothermic, and they hadn't asked the enthalpy of combustion, it was of the reaction i guess. Empirical formula is C6H8O7

    Chemistry Paper 2

    Are you guyz sure it was -129? Coz the enthalpy change of the reaction worked out to +129 for me and my friends. :-/ Variant 22

    yup, correct

    yea

    Chem p22

    Are you guyz sure it was burning in chlorine gas/oxygen gas, coz as far as I remember it was the flame test of the CHLORIDE they had asked, no? Anyway. SiCl4 forms HCl in water, I wrote pH 1. Did they ask the enthalpy change of FORMATION of Methanol or the enthalpy change of the REACTION? I...
