It was pretty easy

 

[saba1996]

Sure ? _ well I doubt

I do have mistakes but it was better than bio 3b!

 

[Manasa]

horrible one ever!!!

 

[syedaliadib]

[Manasa]

[BeBo^.~]

Chem Unit 3 seemed a bit hard; I made silly mistakes.
Like the emperical formula...which was supposed to be among the easiest
2+4+4+2+5 lost about 17 marks already
according to the jan 2012 gradboudry I got a B.

I didn't do the Jan 2013 Chem Unit 3 paper so can someone who did it previously tell me whether it was harder or easier than this one?

wat other mistakes did u make ?

 

[Herald Grove]

wat other mistakes did u make ?

making experiment more accurate by using the stop watch one

also some of the one mark questions of the last question
forget to make my enthalpy change in negative

yea also the first question I didn't notice that sulphate was absent

total is 17 as far as I know, other mistakes might be there

what do you mean sulfate was absent ? :O

 

[Herald Grove]

what do you mean sulfate was absent ? :O

it was absent so the observation should have been no change but I didn't see it and wrote white ppt insoluble

 

[meisen]

seriously did it say absent? i think i wrote the same thing. so what was the formula of the compound?

 

[BeBo^.~]

i wrote no ppt formed colorless solution
abt the compound i wrote C3H8O

 

[Herald Grove]

How did you guys answer the 2 mark question of writing the equation of P with I2?

 

[Herald Grove]

i wrote no ppt formed colorless solution
abt the compound i wrote C3H8O

well good for you! you got them write

 

[meisen]

How did you guys answer the 2 mark question of writing the equation of P with I2?

i wrote P + I2 ---> pI3 i didnt balance it so, i guess that leaves me with just one mark :/

 

[meisen]

well good for you! you got them write

i dont remember seeing anything which said sulfate was absent !
