It is recommended that a liquid ammonia bottle should be opened after cooling it in ice for some time. This is because liquid ammonia:

$2.0 \ g$ of $H_2$ diffuses through a porous container in $10 \ minutes$. How many grams of $O_2$ would diffuse from the same container in the same time under similar conditions (in $.0$)?

State Dalton's Law of partial pressure,provide its mathematical formula,and explain aqueous tension.

If the molar ratio of two different gases is $n_1 : n_2$,then which of the following is $NOT$ necessarily equal to $n_1 : n_2$?

At a constant temperature and pressure,the ratio of the densities of two gases is $1 : 16$. The ratio of their rates of diffusion will be ........

The $\%$ composition by volume of $Cl_2, H_2$,and $N_2$ are in $1:2:7$ by proportion. If the total pressure is $40 \ bar$,find the partial pressures of each gas?
[ Partial pressure $= \frac{\text{Volume } \% \times \text{Total pressure}}{100} ]$
