### Re: Lewis vs. Bronsted-Lowry

The difference between the two is very simple. Lewis acids and bases are defined by their electrons. Acids are electron acceptors and bases are electron donors. For Bronsted, an acid is a proton donor (H+ ion) and a base is a proton acceptor.

Hope that helps!

### Re: Lewis Structure of POCL3?

You would have to leave the P-O bond as a double bond with two lone pair electrons because when you calculate the formal charge, it would be zero at every atom. If you left it as a single bond with three lone pairs, Oxygen would have a FC of -1 and P would have a formal charge of 1. Although you can...

### Self Quiz Question 9

When I divide the grams of C,O, and H by their atomic mass I get 3.28, 3.28, and 7.81. The 7.81 becomes 2.38 when I divide by 3.28. This seems a little strange. Should I multiply by 3 or am I just miscalculating?
