    I need the following chemical equations written and balanced:

    Potassium metal is heated with powdered phosphorus to produce potassium phosphide.

    Cobalt (III) hydrogen carbonate decomposes by heating to give solid cobalt (III) carbonate, water, and carbon dioxide gas.

    Aqueous solutions of tin (II) chloride and sodium sulfide react to give aqueous sodium chloride and a tin (II) sulfide precipitate.

    Solution Preview

    Potassium and phosphorous are both solids (there are several forms of phosphorous, but I will assume here you have elemental P). These will react with heat to form potassium phosphide, a binary ionic salt. Since potassium always has a +1 ionic charge, and a phosphide ion ...

    Solution Summary

    It shows how to write and balance the chemical reaction equations.
