Write balanced equations for the three preceding reactions.

The balanced chemical reaction is done to validate the conservation of mass law because mass is not changed in any chemical equation.

To balance the chemical reaction number of each element on either side of the reaction has been counted and done equally on both sides of the reaction.

Several phosphorous halides, e.g. phosphorous tribromide, phosphorous trichloride and phosphorous pentachloride, are useful for converting alcohols to alkyl halides.
