() predict using the 18-electron rule if the following complexes are stable (use either the donor-pair method or the neutral-ligand method). (1) hand-draw the structure of each complex (if multiple isomers are possible draw only one) (iii) determine the formal oxidation state of the metal in the complex. (a) [fe( (b) [67-cshs)2co)* (c) [67-cshs)(1-csh: )fe(co)] (d) [67-c6h)cr(co)3]

i believe it is c.) 1575 j.

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "
