(a) How would you account for the following :
(i) Actinoids contraction is greater than Lanthanoids contracation.
(ii) Transition metals form coloured compounds.
(b) Complete the following :
`2MnO_(4)^(-)+6H^(+)+5NO_(2)^(-) to`

(a) How would you account for the following: (i) The chemistry of actinoids is more complicated as compared to lanthanoids. (ii) Transition metals form complex compounds. (b) Complete the following equation: 2MnO_4^(-) + 6H^(+) + 5SO_3^(2-) to

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

(a) Account for the following : (i) Cu^(+) is unstable in an aqueous solution. (ii) Transition metals form complex compounds. (b) Complete the following equation: Cr_(2)O_(7)^(2-)+8H^(+)+3NO_(2)^(-)rarr

How would you account for the following? The transition metal compounds are good catalyst.
