Answer 1

When one mole of [Co(NH₃)₅Cl]Cl₂ is treated with excess of AgNO₃ solution, two mole(s) of AgCl_(s) is formed.

Explanation:

The complex [Co(NH₃)₅Cl]Cl₂ ionizes to give a complex cation and two chloride ions.

\[\ce{[Co(NH3)5Cl]Cl2 -> [Co(NH3)5Cl]^{2+} + 2Cl^-}\]

lonizable chloride ions react with AgNO₃ to give 2 moles of AgCl.

\[\ce{2Cl^- + 2AgNO3 -> 2AgCl_{(s)}}\]
