**DrBob222**, Saturday, May 26, 2012 at 8:09pm...........I2==> 2I

I........0.20....0

C.........-x....2x

E......0.20-x....2x

K = (I)^2/(I2)

Substitute from the ICE chart and solve or x. I don't know what the hundred rule is but the answer is within 5% so you can make the approximation that 0.20-x = 0.20.
