"The total volume occupied by a gaseous mixture is equal to the sum of the pure component volumes". This is the __________ law.
-
The osmotic pressure of a solution is directly proportional to the

Acidity or alkanity of a solution is expressed by its pH value, which is defined as (where, [H+] = hydrogen ion concentration in the solution).
-
Raoult's law is not applicable to the

A compound was found having nitrogen and oxygen in the ratio 28 gm and 80 gm respectively. The formula of the compound is
-
The atomic heat capacities of all solid elements __________ with decrease in temperature.
-
Raoult's law states that 'the equilibrium vapor pressure that is exerted by a component in a solution is proportional to the mole fraction of that component'. This generalisation is based on the assumption that the
