I need the following chemical equations written and balanced:
Potassium metal is heated with powdered phosphorus to produce potassium phosphide.
Aqueous solutions of tin (II) chloride and sodium sulfide react to give aqueous sodium chloride and a tin (II) sulfide precipitate.© BrainMass Inc. brainmass.com October 9, 2019, 3:21 pm ad1c9bdddf
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 ...
It shows how to write and balance the chemical reaction equations.
