formula.

 

[DarkNight 001]

formula.

thanks !!!! i'am now relieved ...... cuz many of my friends said we had to draw the structure !!!!

 

[DarkNight 001]

oh and like for the salts analysis table in the not a tranition metal thing i wrote just colourless !!! will that be accepted ?????

oh and like for the salts analysis table in the not a tranition metal thing i wrote just colourless !!! will that be accepted ?????

well i think that will be wrong

ofcourse

 

[Fallen316]

well i think that will be wrong

ever been through a mark scheme ?

 

[uzair2013]

ever been through a mark scheme ?

he wrote just colorless
i think he should have mentioned colrless solution.

 

[Fallen316]

he wrote just colorless
i think he should have mentioned colrless solution.

no, he's fine .

 

[syedhamza]

I wrote leibig instead of reflux. is it correct?
In the second last part of last qs. i just wrote value obtained from graph at 50 degree C. Is it worth 2 marks?
I also wrote that Barium sulphate obtained as residue should b dried in an oven? Some of my friends say that oven cant b used? is it? is filter paper necessary?
Please reply me IF U ARE FULLY CONFIRM and as soon as possible.

 

[pakisatan123]

what was da mass of barium sulfate

 

[Ikram Khaliq]

i wrote a pipette filler. but the purpose i wrote was to prevent the chemicals from splashing and causing harm.

 

[Ikram Khaliq]

thanks !!!! i'am now relieved ...... cuz many of my friends said we had to draw the structure !!!!

they specifically asked for the structural formula.

 

[17194]

Yea the question said to write the structural formula.

 

[Tharindu]

CH3COOCH2CH3

 

[Fallen316]

CH3COOCH2CH3

yea , but i wrote it like.
C4H8O2
this.

 

[Tharindu]

yea , but i wrote it like.
C4H8O2
this.

I think its wrong....but if it's 2 marks u myt get 1

 

[17194]

CH3COOCH2CH3

This is exactly what I wrote too.

 

[Tharindu]

This is exactly what I wrote too.

It's the exact thing u need to write...lol there is only one correct answer p

 

[Fallen316]

I think its wrong....but if it's 2 marks u myt get 1

it is right. its the same formula.
both are correct, check any mark scheme
