Answer 1

Answer:

1)

1. Compressibility factor = PV/nRT

Explanation PV = nRT is for ideal gas but many gases deviates from ideality nd hence compressibility factor (c) introduced in an ideal gas equation.

PV = cnRT

c = PV / nRT.

2. Cause of negative deviation from Ideal behaviour: Intermolecular forces of attraction present.

In ideal gas behaviour its assumed that gas molecules shows no Intermolecular interactions due to lack of attractive or even repulsive forces.

But in reality there are attractive forces.

3. Two parameter description of real gas : Vander Waal's equation.

4. Substance that produce large amount of ions in solution : L. Strong electrolyte.

5. Red Litmus Turns Blue : N. Phenomenological property of Base.

6. Oxidation: H. Increase in Oxidation Number

The species said to be oxidized when it looses electrons which cause increase in oxidation state.

7. Activity Series: Scheme used to predict whether reaction occur or not.

8. Molarity definition: Moles/Litre.

Molarity = # of moles of substance / Volume of solution in Ltr.

9. Dalton's Law of partial pressure: P = $\Sigma$ Pi

10. Reduction: Decrease in oxidation number.

The species said to be reduced when it accepts electrons which cause decrease in oxidation state.

11. Effusion: E. Transport of material through small aperture.

12. Substance dissociates in few % into ions in solution: G. Weak electrolyte.

13. Property of an Ideal gas : Particle size negligible.

Explanation: Ideal behaviour of gas molecules is due to assumption that gas molecules has negligible size.

14. Postulate of kinetic theory of gas : Particles move irandom straight line motion.

15. Blue litmus turn red: J. Phenomenological property of Acid.
