Solid phosphorus trichloride is produced by reacting solid phosphorus and chlorine gas.
2P + 3Cl2 -----> 2PCl3
is that right?
Thanks. Can you explain to me when I have to add charges to my the thing? and when I can't?
Atoms are neutral and carry no charge. Ions have a charge.
And I don't know if your professor is using P4 for phosphorus or not. If so, your equation needs adjusting.
