If S and T are two sets such that S has 21 elements, T has 32 elements, and S ∩ T has 11 elements, how many elements does S ∪ T have
It is given that: n(S) = 21, n(T) = 32, n(S ∩ T) = 11 We know that: n (S ∪ T) = n (S) + n (T) – n (S...

If X and Y are two sets such that X has 40 elements, X ∪Y has 60 elements and X ∩Y has 10 elements, how many elements does Y have
It is given that: n(X) = 40, n(X ∪ Y) = 60, n(X ∩ Y) = 10 We know that: n(X ∪ Y) = n(X) + n(Y) – n(X ∩ Y) ∴ 60 = 40...

Give reason (a) C and Si are always tetravalent but Ge, Sn, and Pb show divalency. (b) Gallium has higher ionization enthalpy than Al.Explain.
(a) Ge, Sn and Pb show divalency due to inert pair effect, Pb2+is more stable than Pb4+. (b) Due to poor shielding effect of d-electrons in Ga, effective nuclear charge increases...
