Give formulas corresponding to the following names:(a) Potassium tris(oxalato)chromate(III)(b) Tris(ethylenediamine)cobalt(III) pentacyanoiodomanganate(II)(c) Diamminediaquabromochloroaluminum nitrate

Draw the crystal field diagram of [W(CO)6]. Determine the  (a) Electronic configuration in terms t2geg  (b) Number of unpaired electrons  (c) Ligand field stabilization energy in terms of ΔO or ΔT

A coordination compound has the following composition (by mass %): 23.53% Co; 42.47% Cl, and 34.00% NH3. When 4.91 g of the compound is dissolved in 75.0 mL of deionized water, and the solution is reacted with an excess of AGNO; solution, it yields 5.60 g of AgCl precipitate. (a) Determine the empirical formula of the compound and write in the form of Co(NH;),Cl, (where x and 24. y are simple integers), and calculate its molar mass. (Assume the compound contains only one Co atom). (b) Deduce the number of chloride (Cl) as counter ions and as ligand, respectively. (c) Write the Werner's formula of the compound and give its systematic name. (Answers: (a) Co(NH3);C13; molar mass = 250.43 g/mol; (b) 2 Cl are counter ions and one is ligand; (c) [Co(NH3);CI]Cl2 = pentaammonechlorocobalt(III) chloride)

Ammonia and potassium iodide solutions are added to an aqueous solution of chromium(III) nitrate. A solid is isolated (compound A) and the following data are collected: When 0.105 g of compound A was strongly heated in excess oxygen, 0.0203 g of chromium(VI) oxide was formed. In a second experiment it took 32.93 mL of 0.100M HCl to titrate completely the ammonia present in 0.341 g of compound A. Compound A was found to contain 73.53% iodine by mass. The freezing point of water was lowered by 0.62oC when 0.601 g of compound A was dissolved in 10.00 g of water.   What is the formula of the compound A?
