Assertion: The value of Vander Waal’s constant ‘a’ for ammonia is larger than that of nitrogen Gas.

Let x be the smaller of the two consecutive even positive integers. Then, the other integer is x + 2.  Since both the integers are larger than 5,  x > 5 ..........................

(b) : Molar heat capacity = Molar mass × specific heat capacity So, the molar heat capacities at constant pressure and constant volume will be 28CP and 28CV respectively Therefore, 28CP –...

(c) Assertion is correct, reason is incorrect 

 ( P + an2 /V2 ) (V – nb) = nRT  a gives the idea of magnitude of attractive forces between the molecules of the gas while b is a measure...

a) NH3 will have larger value of a because of H – bonding.  b) NH3 will have larger value of b due to larger molecular size.

(d)Correct explanation: Nitrogen has stable exactly half filled electronic configuration but oxygen does not have.

(B)If both assertion and reason are true, but reason is not the true explanation of the assertion.

The correct answer is (C) Raghu

(i) No, change in colour. (ii) Red litmus turns blue.

Upward force is larger than the force of gravity.
