how was chem paper 33??

[karishma92]

wat did u guys get for FA3, FA4, FA5, and FA6???

 

[trk1994]

i got for fa6 Ba :S:s is t ryteeeeee???? n for fa5 u,, sulphate and fa4 carbonate and fa3 sulphite

 

[mrchemistry420]

FA1 naoh
FA2 hcl
FA3 sodium metabisulfite
FA4 sodium carbonate
FA5 sodium sulfate
FA6 leab (II) nitrate (solid)
FA6 lead (II) nitrate (solutn)

ya thats the rite answer...

 

[heetamlani]

yeah agree its perfect. but how did you describe graph in question 1??
& what temperature change you get the maximum? (when 35 cm^3 of NaOH was taken)

 

[karishma92]

every one got different temp change...

 

[trk1994]

i guess i got 19

 

[karishma92]

i got 11 i guess :/

 

[karishma92]

FA1 naoh
FA2 hcl
FA3 sodium metabisulfite
FA4 sodium carbonate
FA5 sodium sulfate
FA6 leab (II) nitrate (solid)
FA6 lead (II) nitrate (solutn)

Q 2 : for FA3 FA4 and FA5 i used hydrochloric acid
FA3 suphite
FA4 carbonate
FA5 sulphate
FA6 ammonia and reagent was sodium hydroxide :/
i only wrote these so is dis right???
Q 1 : temp change was 11 and volume for FA1 was 25
so to find da heat energy i used 4.3x11x25
and for da 2nd part i got da ans in cm^3
and in da next part i used da cm^3 which was 50 and divide it wid 1000 to get dm^3 cx da ratio for hcl and naoh was 1:1
so is all correct????

shit! I got Mg for FB6..will they cut marks for whole observation too?

mmmm i dont fink so
