A container having a pin-hole contains equal masses of `SO_2` and `CH_4`. Ratio of moles of `SO_2` and `CH_4` effused out initially is

A gaseous mixture contains equal mass of CH_(4) and SO_(2) gas. The mole fraction of SO_(2) in the mixture is

Two flasks A and B of equal volume containing equal masses of H_2 and CH_4 gases are at 100 K and 200 K temperature, respectively. Which of the following is true about the total KE (kinetic energy) ?

A gaseous mixture (He and CH_(4)) which has density (64)/(246.3) gm/litre at 1 atm & 300 K is kept in a container. Now a pinhole is made on the wall of the container through which He(g) and CH_(4) effuses. What will be the composition of the gas mixture [n_(He) : n_(CH_(4))] effusing out initially?

One mole of methane (CH_4) contains

The ratio of rates of diffusion of SO_(2) , O_(2) and CH_(4) is

A container contains O_(2) , He and SO_(2) gases such that mass of SO_(2) is double the mass of O_(2) and mass of He is half the mass of O_(2) gas. The mole fraction of SO_(2) gas in the mixture is:

A mixture containing one mole of BaF_(2) and two mole of H_(2)SO_(4) will be neutralised by:
