The elevation of boiling point of 0.10 m aqueous CrCl3 .xNH3 solution

1.	The elevation of boiling point of 0.10 m aqueous CrCl3 .xNH3 solution is two times that of 0.05m aqueous CaCl2 solution. The value of x is____. [Assume 100% ionisation of the complex and CaCl2 , coordination number of Cr as 6, and that all NH 3 molecules are present inside the coordination sphere]
Answer» Correct answer is 5.00 2Tb=i1×kb×0.10 -(1) Tb=i2×kb×0.05 -(2) Solving (1) and (2) , We get i1=i2 Now i2 (for cacl2) = 3 So, i1=3 The country point hence formed is Cr[(cl) (nh3) 5]cl2.

How do biofertilisers enrich the fertility of the soil?
Read carefully the passage and select the correct answer out of given four options:Biofertilizers are organisms that enrich nutrient quality of the soil. The important sources of biofertilizers are bacteria, fungi and cyanobacteria. The symbiotic association of Rhizobium with the root nodules of leguminous plants is the common example. These bacteria convert atmospheric nitrogen into nitrogenous compound and fix in the soil.The organisms which enrich the nutrient quality of the soil are called(a) Microbes(b) Biofertilizers(c) Yeast(d) Biopesticides
