A container of volume 0.166 m^3 contains a mixture of 1.60 g oxygen and 2.80 g nitrogen at constant temperature 300 K. Find the pressure of the mixture.

1 mol of He at 57^@C is mixed with 1 mol of Ar at 27^@C . Find the temperature of the gas mixture .

A closed container of volume 0.02 m^3 contains a mixture of neon and argon gases at a temperature of 27^@C and pressure of 1 times 10^5 N.m^-2 The total mass of the mixture is 28 g. IF the molar masses of neon and argon are20 and 40 g//mol respectively . find the masses of the individual gases in the container assuming then to be ideal. [R=8.314 J.mol^-1.K^-1 ]

Write down the thermochemical equations for the following reactions: (i) A 1 mol sample of methane gas reacts with 2 mol of oxygen gas to form 1 mol of carbon dioxide and 2 mol of water. In this reaction, 890.5 kJ of heat is produced. (ii) A 1 mol sample of carbon (graphite) reacts with 1 mol of oxygen tof orm 1 mol fo carbon dioxide gas. the heat evolved in this reaction is 393.5 kJ. (iii) 6 mol of carbon dioxide gas reacts with 6 mol of water to form 6 mol of oxygen gas and 1 mol of glucose. the heat absorbed in this reaction is 2200 kJ.

Carbon dioxide decomposes to form its own volume of oxygen. Find the molecular formula of carbon dioxide if its vapour density is 22.

At 300 K, an evacuated cylinder with a volume of 10Lgt is filled with 2 g of H_(2) and 2g of D_(2) . Find the pressure of the gas mixture in the cylinder. Will the presure be the samme if the container is cubical having the same volume?
