dude u r rite about that

 

[WhereAmazingHappens]

ok, so i forgot the question. But sodium still burns with a yellow flame in chlorine.

k but sulfur burns with blue flame

 

[AdeelRox]

does mg burns with coloured flame?

 

[Nisrit Pandey]

kindly forward it here too if u get it

for sure man

 

[WhereAmazingHappens]

does mg burns with coloured flame?

dont think so

 

[raihan1904]

does mg burns with coloured flame?

no in Period 3 only Na burns with yellow flame!! others burn in white (or offwhite)flames!!

Sulfur also burns in blue flame for gods sake.....

Thanks. Are a you a Bangali too?

 

[raihan1904]

yea!!
lol u shud hav guessd it from my profile pic

Wonder how many marks would have been lost if i drew the cis trans isomers in the usual displayed formula rather than skeletal formula? :/

 

[thunderingthunder]

The emperical formula for sure was C6H8O7 because the relative number of moles ratio was 1:1.33:1.16 and kept on multiplying by the numbers till 6 and the ratio came as 6:7.99:7.02 which could be rounded off better than other numbers to give an accurate answer
the functional groups were alcohol and ketone . the structural formula of the compound was HOH2CCOCH2OH

what if i wrote CHO only??how manny marks will be deducted?

 

[WhereAmazingHappens]

yeah.. sorry my bad

 

[AdeelRox]

dude it was of two marx i guess and that i am very sory to say that u mite loose both the marx. i hope u dont loose any

 

[WhereAmazingHappens]

yeah.. sorry my bad

Dude do u remember how many marks it was for the enthalpy question they asked how rate of formation depends on temp and pressure....

 

[AdeelRox]

3

 

[WhereAmazingHappens]

3

3 for each?

 

[AdeelRox]

nup 3 for the whole i also did that wrong i thought it t be a reversible reaction.what i didnt noticed was dat there wux jst 1 arow. lolz

 

[WhereAmazingHappens]

nup 3 for the whole i also did that wrong i thought it t be a reversible reaction.what i didnt noticed was dat there wux jst 1 arow. lolz
