Did I do this single replacement reaction right? (the equation) and should i use iron 2 or iron 3?
-
so we did a lab in chem where we put iron nails into a copper (II) chloride solution so since the iron reacted and copper was produced, would the equation be Fe + CuCl2 ---> FeCl3 + Cu and then to balance it, is it 2Fe + 3CuCl2 ---> 2FeCl3 + 3Cu or would you use iron 2. iron with a charge of 3 is more common, but a charge of 2 would make the equation like easier to balance?

Answer:
I think you should use the iron two equation. There were originally two chlorine atoms on the reactant side, another isn't just going to appear out of nowhere. So iron (II) makes sense to me. that equation will already be balanced for you so no extra work to be done.
