Rearrange the following taxonomic categories in a proper sequence from smaller taxon to higher one:

Knowing the electron gain enthalphy values for OrarrO^- and O rarrO^2- as -141 and 702 kJ mol^- respectively, how can you account for the formation of a large number of oxides hav-ing O^2- species and not O^- ?

What are the reasons that you can think of for the arthropodfs to constitute the largest group of the animal kingdom?

A man walking briskly in, rain with speed v must slant his umbrella forward making an angle theta with the vertical. A student derives the following relation between theta and v, tantheta = v and checks that the relation has a correct limit: as v rarr 0, theta rarr -0 , as expected.. (We are assuming there is no strong wind and that the rain falls vertically for a stationary man). Do you think this relation can be correct? If not, guess the correct relation.
