1.	A bottle of NH_(3) gas and a bottle of dry HCl gas are connected through a long tube. The tube is opened simultaneously at both the ends. White fume of NH_(4)Cl is formed ……………..
Answer» throughout the length of the TUBE near HCl BOTTLE near `NH_(3)` bottle at the centre of tube Solution :Atomic pressure in `NH_(3)` gas = 17 gm `mol^(-1)=M_(1)` Atomic pressure in HCl gas = 36.5 gm `mol^(-1)=M_(2)` According to Grapham.s gas diffusional Law,Whose atomic pressure is high its diffusion is slow.`(r=(1)/(sqrt(M)))` The atomic pressure of HCl (36.5 gm `"mole"^(-1)`) is more then the atomic pressure of `NH_(3)` (17.0 gm `"mole"^(-1)`) So, the diffusion of HCl is LESS. `THEREFORE` The diffusion of HCl is very less. `therefore` So, the FUME of `NH_(4)Cl` is formed `NH_(3)` bottle.
