Which one of the following complexes will have four isomers ?
[Co(en)3]Cl3

A coordination complex compound of cobalt has the molecular formula containing five ammonia molecules, one nitro group and two chlorine atoms for one cobalt atom. One mole of this compound produces three mole ions in an aqueous solution. On reacting this solution with excess of AgNO3 solution, we get two moles of AgCl precipitate. The ionic formula for this complex would be
[Co(NH3)5(NO2)]Cl2
[Co(NH3)5Cl][Cl(NO2)]
[Co(NH3)4(NO2)Cl][NH3)Cl]
[Co(NH3)5][NO2)2Cl2]
Which one of the following statement is not correct?
Mercury (II) iodide dissolves in excess of potassium iodide solution
Tin (IV) chloride is made by dissolving tin solution in concentrated hydrochloric acid
Zinc dissolves in sodium hydroxide solution
Carbon monoxide reduces iron (III) oxide to iron
