The heat librerated on complete combustion of 1 mole of CH_(4) gas to CO_(2)(g) and H_(2)O(l) is 890 kJ. Calculate the heat evolved by 2.4 L of CH_(4) on complete combustion.

What pressure (in atm) will be exerted by a 1.00g sample of methane, CH_(4) in a 4.25L flask at 115^(@)C ?

Under identical conditions of pressure and temperature, 4 L of gaseous moxture ( H_(2) and CH_(4) ) effuses through a hole in 5 min whereas 4 L of a gas X of molecular mass 36 takes to 10 min to effuse through the same hole. The mole ratio of H_(2):CH_(4) in the mixture is:

CH_4 (gas) is taken at (0.2)/(1.01325) atm pressure. Density of gas is 1.44 g//l and most probable speed is x xx10^2m//s , in the given condition. The value of x is:
