Worksheet error
On the "Monster Equation Balancing/Reaction Type Worksheets" from 012106, on page 2 of the file, problem 6 d, there is a subscript error that makes balancing impossible.
The correct equation should have iron II chloride (FeCl2)and NOT iron III chloride (FeCl3) as the first reactant. This is a double replacement reaction so, as you will eventually learn, nothing happens to the charges of the cations or anions in such a reaction. Therefore, iron starts as a +2 ion and ends up as a +2 ion.
Thanks to Evelyn for pointing this out to me. It's good to know that some people are doing the hw carefully. Cheers.
