Trying to write a reaction and balance it. Need help.

[Cory-Reed]

I'm stuck ...

I am writing a lab report, and writing this out would kinda just be kool, but not required. The reaction forms a brown, rust colored precipitate, but I can't write the reaction for the life of me. (nor find it online)

CH₃CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂COONa (also known as Sodium Stearate, or soap) + FeCl₂


CH₃CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂COONa (dissolved in 5 mL of distiled H₂O) + FeCl₂ -->


I am also having trouble with these reactions ...


CH₃CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂COONa (dissolved in 5 mL of distiled H₂O) + CaCl₂ -->

CH₃CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂COONa (dissolved in 5 mL of distiled H₂O) + MgCl₂ -->

CH₃CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂COONa (dissolved in 5 mL of distiled H₂O) + tap water -->


Please help ...
