Concepts
Dalton’s Law
Pressure of mixture of non-reacting gases is equal to sum of their partial pressures under similar conditions.
[lyte id=”RqffPYOoxd8″ \]
Points to Remember
The partial pressure of each gas is equal to the mole fraction […]
Charle’s Law
Volume of gas is directly proportional to temperature at constant pressure.
[lyte id=”MNNJwfWMUf0″ \]
At constant pressure,
V1/T1 = V2/T2
where T1 refers to the temperature of gas-1 and T2 refers to temperature of gas-2, V1 […]
Boyle’s Law
Volume of gas is inversely proportional to pressure at constant temperature.
[lyte id=”3o7XNAPpUKg” \]
When mass and temperature is kept constant,
P1 V1 = P2V2
where P1 refers to the pressure of gas-1 and P2 […]
Electronegativity
Tendency of an atom to attract the shared pair of electrons towards it
Dative Bond
Covalent bond in which both the shared electrons come from one atom
Covalent Bond
Bond formed by mutual sharing of electrons between combining atoms
Electrovalency
Number of electrons which an atoms gains or loses
Electrovalent Bond
Electrostatic force which holds the oppositely charged ions together. Also called as Ionic Bond
Chemical Bond
The attractive forces which holds the particles such as atoms, ions and molecules together
