$\begingroup$ @Steve Lantz, I did rework it with that value for the Ka and got the same answer as MaxW. I am in taking a general chemistry course in college, so I think the method is correct. The system must be wrong. Completely aside from the answer to the problem, your post was very interesting.

Mar 12, 2013 · Chemistry. H3BO3 -> H+ + H2BO3-Why doesn’t H3BO3 break down to something with H3O+ because it is a weak acid? I know many weak acids break down to something with H3O+ like HCN, C6H5COOH, HNO2, and HF.

There are three basic steps to determining the bond angles in a molecule: > 1. Write the Lewis dot structure for the molecule. Assume that you must determine the bond angles in “BF”_3. “B” is less electronegative than “F”, so “B” becomes the central atom. If we have three “F” atoms, that means that we are going to use all three electrons from the “B”.
