Question

state 5 laws in chemistry in first chapter of class 11th (some basics of chemistry)

Answer 1

These are some of the basic laws of chemsitry:


Boyle's Law:
At constant temperature, the volume of a confined gas is inversely proportional to the pressure to which it is subjected.

PV = k


Dalton's Law:
The pressure of a mixture of gases is equal to the sum of the partial pressures of the component gases.


Faraday's Law:
The weight of any element liberated during electrolysis is proportional to the quantity of electricity passing through the cell and also to the equivalent weight of the element.



Graham's Law:
The rate of diffusion or effusion of a gas is inversely proportional to the square root of its molecular mass.


Henry's Law:
The solubility of a gas (unless it is highly soluble) is directly proportional to the pressure applied to the gas.



Periodic Law:
The chemical properties of the elements vary periodically according to their atomic numbers.
