Answer from: westes0376

Part A: Hexacyanoferrate (III)

Part B: (II)

Part C: Dichlorobis(ethylenediamine) Chromate (II)

Part D: Triaquocarbonylnickel (II) Sulphate

Part E: Potassium (II)

Explanation:

For naming the complex ions there is a specific rule

Nomenclature of the complex ions are as follow

write a correct formulaeIndicate the oxidation number of metal in the complexThe oxidation number should write in the roman numeral in perenthasis after metal nameLigand named before the metal ionLigan can be named in following order

* 1st negative, 2nd neutral, 3rd positive

* If there are more than 2 same charged ligand the write in

alphabetical order.

Write prefix i.e di, tri, tetra for multiple monodentate ligandsAnions name end at ido the replace the final name.Neutral ligands named as their usual name, but there are some exceptions such as

NH3 named as ammine

H2O names aqua or aquo

CO named ascarbonyl

NO named as nitrosyl

If the complex is an anion, then name of the central atom will end in -ate, and its Latin name will be used except for mercuryThe name of full complex will end with cation or anion with separate word.

Keeping the rules in mind the complexes named as following.

Part A:

[Fe(CN)₆]³⁻

Name of the Complex : Hexacyanoferrate (III)

Part B:

[Cu(NH₃)₂(H₂O)₄]²⁺

Name of the Complex : (II)

Part C

CrCl₂(en)₂

Name of the Complex : Dichlorobis(ethylenediamine) Chromate (II)

Part C

[Ni(H₂O)₃(CO)]SO₄

Name of the Complex : Tetraaquocarbonylnickel (II) Sulphate

Part E

K₄[Pt(CO₃)₂F₂]

Name of the Complex : Potassium (II)

For a research project, a student decided to test the effect of the lead(ii) ion (pb2+) on the ability of salmon eggs to hatch. this ion was obtainable from the water‐soluble salt, lead(ii) nitrate, which the student decided to make by the following reaction. pbo(s) + 2 hno3(aq) → pb(no3)2(aq) + h2o losses of product for various reasons were expected, and a yield of 86.0% was expected. in order to have 5.00 g of product at this yield, how many grams of pbo should be reacted? (assume that sufficient nitric acid, hno3, would be used.)
