Write the formulas for the follow co-ordination compounds
Tetraammineaquachloro cobalt (III) chloride

Explanation

`("Tetraamminediaqua")/("Ligand")("Cobalt (III)")/("Metal")("Chloride")/("Counterion")`
`overset(III)([Co(NH_(3))_(4)(H_(2O)_(2)]Cl_(x))`
To find the value of x, we have to find the charge on the complex.
`overset(III)([Co(NH_(3))_(4)(H_(2O)_(2)]^(x+)+3+4xx0+2xx0=x, x=+3`
So, the formula of the complex is `[Co(NH_(3))_(4)(H_(2)O)_(2)]Cl_(3)`
