1.	How much energy is required to ionise an `H` atom if the electron occupies `n=5` orbit? Compare your answer with the ionisation enthaply of `H` atom (anargy required to remove the electronic from `n=1` orbit).
Answer» `E_(n)=((2.18xx10^(-18)J))/(n^(2))` `=(2.18xx10^(-18)J)/(5^(2))=8.72xx10^(-20)J` `1E` of `H=(2.18xx10^(-18)J)/((1)^(2))=2.18xx10^(-18)J`

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.
