The reaction of with acetone and hydrolysis of the resulting product gives
17.4 % (mass / volume) K_{2}SO_{4} solution at 27°C is isotonic to 5.85% (mass / volume) NaCl solution at 27°C. If NaCl is 100% ionised, what is % ionisation of K_{2}SO_{4} in aq. solution?
Among the following ore how many example of carbonate ore:
lime stone, malachite, dolomite, Horn silver, Flourspar, Calamine, Cuprite.
Identify the element for given which have the most negative electron gain enthalpy. Write atomic number of that element as answer :
P , S, Cl, F, Br
Element 'X' has maximum electron affinity in periodic table then find the number of elements which have low first ionisation energy as compared to element 'X' ?
F, Na, S, Si, P, Ar
If number of low spin complexes are 'X' then find the value of 1/x.
