A bottle of dry ammonia and a bottle of dry hydrogen chloride connecte

1.	A bottle of dry ammonia and a bottle of dry hydrogen chloride connected through a long tube are opened simultaneously at both ends. The white ammonium chloride ring first formed will beA. At the centre of the tubeB. Near the hydrogen chloride bottleC. Near the ammonia bottleD. Throughout the length of the tube
Answer» Correct Answer - B Rate of diffusion `prop sqrt(1// "Mol. Mass")` . Mol. Mass of `HCl gt` Mol. Mass of `NH_(3) NH_(4)Cl` ring will first formed near the HCl bottle because rate of diffusion of `NH_(3)` is more than that of HCl ( because `M_(NH_(3)) : M_(HCl)=17:36.5)`. SO `NH_(3)` will reach first to the HCl bottle & will react there with HCl to form `NH_(4) Cl` ring

The density of a gas filled in electric lamp is `0.75kg//m^(3)` . After the lamp has been switched on, the pressure in it increases from `4xx10^(4)` Pa to `9xx10^(4)` Pa. What is increases in `u_("rms")` ?A. 100B. 200C. 300D. None of these
In a glass tube columns of water and mercury appear as shown. This is best attributed to the differences in their:A. densitiesB. molar massesC. surface tensionsD. viscosities
The volume of real gases often exceed those calculated by the ideal gas equation. These deviations are best attributed to the:A. attractive forces between the molecuels in real gases.B. dissociation of the molecuels in real gases.C. kinatic energy of the molecules in real gases.D. volumes of the molecules in rel gases.
A container holds 3 liter of `N_(2(g))` and `H_(2)O_((l))` at `29^(@)C` The prssure is found to be 1 atm The water in container is instantaneously electrolysed to give `H_(2)` and `O_(2)` following the reaction `H_(2)O_(l) rarrH_(2(g)) +(1)/(2)O_(2_(g))` At the end of electrolysis the pressure was found to be `1.86atm` calculate the amount of water present in the container If the aqueous tension of water at `29^(@)C` is `0.04 atm ` .
