too much to do, no time to shower

Ionic equation balancing is confusing. Particularly when you add two half equations and the complete equation you get is judged to be from PLANET TEN! by webassign. wtf, mate?

Saturday's miles: 2.8
Sunday's miles: 3.4
Monday's miles: 12.9
Miles out of Hobbiton: 1120.3
Miles out of Rivendell: 655.3
Miles out of Lothlórien: 200.3
Miles to Rauros Falls: 208.7

Biked home via 35th instead of Burke-Gilman. Shorter route, but harder biking. But also fun, it was new. Got home, did a bunch of homework, walked down the hill to see Lewis Black's appearance at Third Place, came home and did more homework. Stupid bases. Now I have to go to bed so I can get up early to shower in the morning.

If you think ionic equation balancing is hard, wait until you start doing rates of reaction and chemical equilibrium for them!

It has been 25 years since I took college chemistry, but I still remember how to balance various chemical equations. I hope that by, "two half equations" you mean a matched pair of full equations, one that creates ions and one that consumes them. Just make sure that the number of ions created equals the number of ions consumed. If that gives you fractions, multiply everything through by a number that eliminates the denominators.

That part's fine, I can do those. These are in a random mix of acid and base solutions and where I'm having trouble is with all the water, hydroxide, and H+ interactions. :-p
