(show all your works and make sure that you answer all questions from part a to part b. Thanks anyone who help me all questions below)

a. briefly explain: among this group of seven metal ions (Ag1+, Hg2+, Mo6+, Nb5+, Mn7+, Y3+, Zr4+) there are two groups. organize the ions into the two groups and ID each group

b. several isomers of formula, CoCrC6H18N12, with both Co and Cr as +3: for each of the following isomers, give both the name and formula:

(i)the Co complex ion has six ammonia groups

(ii)the Co complex ion has one cyanide and five ammonia groups

Explanation / Answer

a.The two groups are:

1. Ag+1, Hg+2 having electronic configuration of ns0nd10

2. Mo6+, Nb5+, Mn7+, Y3+, Zr4+ having electronic configuration of inert gases.

b. i. [Co(NH3)6][Cr(CN)6] - HexaammineCobalt(III)hexacyanoChromate(III)

ii. [Co(CN)(NH3)5][Cr(NH3)(CN)5] - PentaamminecyanoCobalt(III)pentacyanoamminoChromate(III)
