the plannin part......am going 2 get anythin....pliz show me hw it was done......my hnds r tremblin remembrin dat question


what I can conclude is that u have to take fixed mass of ammonim nitrate and heat it. the gas which wil evolve, wil contain no2 and h20 vapurs


by installing liebeg condesor we can condense water molecules.

the remaing will be no2 gas it should be coolected in syringe.

we have to show the volume of syringe gas with respect to the mass/ moles of ammonim nitrate we used. using eq. given at frst page.

lets suppose u took 1.0g of AMMONIUM nitrate means u have taken 0.0125 moles of it

now molar ratio is 1 : 1 of ammonium nitrate and NO2 so same moles wil be produced of No2 convert them to the volume

there wil be 300cm^3 of volume of No2 to be collected

repeat the experiment to get a set of values to plot a graph

thats what i think

hey.....how would you collect water using liebeg condesor...wont it fall back in the boiling tube.....it was written how it will be collected.......

i used water bath instead.. was that okay??

when the gas wil evolve it wil move through the pipe covered with crushed ice(liebeg condensor).

this wil condense the water vapours to the drops of water. those drops wil fal down and u can collect them in a flask.

wheras, on condensing the gas no2 which is gas at rtp wil remain gas and u can collect it by installing a syringe at the end of the condensor
