    Paper 1 and 2 were fine.....
    Paper 3 was pretty hard....

    For the question with the heat of neutralisation of NAHCO3....

    5 grams was added to 50 cm3 of acid..... when calculating the mass.... do we take it as 50g..( density =1g/cm3) .. or 55?..(50 +5g of NAHCO3)

    wowwwwwwwwwwwwwwwwwwwwwwwwww thanx... but the thing is i included the gas az well N-(g) + e- gives N2-(g)

    that was so hard...that 3b paper was a mother ****er. sorry but i found that beyond my capabilities it was like rocket science. i didnt prepare very well but it doesnt mean i wouldnt have done as bad as i did. i dont think i ggot 50% tbh and thank god other ppl found it difficult i thought i was very very stupid. last question was easy but it was worded retardedly and i hate moles i got half of tehm wrong i think i dont know.
