The number of effusion steps required to convert a mixture of H2 and O2 from 240:1600 (by mass) to 3072:20 (by mass) is?

Number of Faradays required to convert 1 mol of Cr_(2)O_(7)^(2-) into Cr^(3+) ions is :

Pressure of a mixture of 4 g of O_2 and 2 g of H_2 confined in a bulb of 1 litre at 0^@C is

Calculate the number of molecules in one drop of H_(2) O whose mass is 0.05 g

A gaseous mixture containing equal mole sof H_(2),O_(2) and He is subjected to series of effusion steps. The composition (by moles) of effused mixture after 4 effusion steps is x:1:y rspectively. Then find the value of ((x)/(y)).

The number of electrons required to balance the following equation are : NO_(3)^(-)+4H^(+)rarr2H_(2)O+NO

Find vapour density of mixture having 64% by mass of CH_(4) , 32% by mass of O_(2) and remaining H_(2)

To obtain maximum mass of NO_(2) from a given mass of a mxiture of NH_(3) and O_(2) , the ratio of mass of NH_(3) to O_(2) should be 2NH_(3)+(7)/(2)O_(2) rarr 2NO_(2)+3H_(2)O

Calculate relative rate of effusion of O_(2) to CH_(4) from a container container containing O_(2) and CH_(4) in 3 :2 mass ratio.

The minimum mass of mixture of A_(2) and B_(2) required to produce at least 1 kg of each product is : (Given At. Mass of 'A' = 10 : At. Mass of 'B' = 120 )

Molecular mass of H_(2)O_(2) is
