Writing and Balancing Chemical Equations
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.© SolutionLibrary Inc. solutionlibary.com 9836dcf9d7 https://solutionlibrary.com/chemistry/general-chemistry/writing-and-balancing-chemical-equations-1v6
...as a -3 charge, the resulting compound is K3P since the salt must be neutrally charged.
3K(s) + P(s) K3P(s)
The second reaction is somewhat trickier to balance. It is also trickier to determine the charge on each ion. The following is true: Cobalt (III) ...
