how do you do it!?!? we have this homwork and our teacher hardly taught us sumthing and im stuck in number 2 which is phosphoric acid. when i looked up in the internet, they all dont tell how exactly it turned into H3PO4. does anyone how it turned out like this? and do you know any understandable rule for this?
to those who could answer,,,, THANX!!!!!!!!

Not that I understand your question exactly...but this is how H3PO4 is built. Start with Phosphorus - it has 3 valence electrons (3 sites that want to bond to another electron). So imagine 3 open spaces on the P. Now oxygen. It has 2 valence electrons - 2 sites that want electrons, but you have 4 oxygens. Finally, you have Hydrogen with its one lonely valence electron, so it has one bondable site. Now you have to do some work to figure out how it all fits together:
H-O-O-P-O-O-H
There should be a Hydrogen above and connected to the P but the computer will not let me put it there.This configuration works... If you count it up, P has 3 lines, each O has 2 lines and each H has 1 line.
Hope that helps.

i can answer your question its is pretty easy
okay H3PO4 is phosphoric acid right and the charge of phosphoric acid is -3 right and and you have balance this with hydrogens inorder to form and acid and the charge of hydrogen is +1 right
you need three hydrogen( +1 ) to balance the charge of PO4 which is -3
thats why H3PO4 is balanced

usually the acids and alcohols etc.. have compounds attatched to them. Acids you can always tell because of the names such as phosphoric, which is based off the compound phosphate(PO4 -3). If you want answers for the rest just post them.

aww that really is the formula for phosphoric acid.. u have to memorize all the formulas.. sadly.. =[ there really is no rule how it turned out like that, its just.. like that and u have to remember those formulas, especially the acids like the sulfuric acid, etc.
