How will you account for the following :
(a) (i) The chemistry of actnoids is more complicated as compared to lanthanoids .
(ii) Transition metal from complex compounds.
(b) Complete the following equations :
`2MnO_(4)^(-)+6H^(+)+5SO_(3)^(2-) to `

Explanation

(a) (i) The members of the actinoid family exhibit more variable oxidaton states as compared to Lanthanoids . Moreover, most of the elements are of radioactive nature. Therefore, chemistry of Actinoids is more complicated than that of Lanthanoids.
(ii) N/A
(b) `2MnO_(4)^(-)+6H^(+)+5SO_(3)^(2-) to 5SO_(4)^(2-)+3H_(2)O+2Mn^(2+)`.
