Homework Help: To DrBob222

Posted by Sara on Saturday, April 24, 2010 at 9:57pm.

Can you please explain thoroughly to me about all this.

Why do we criss cross the formulas of compounds?

How do we find out which combining capacity to use if there are more than one? Is there a special formula we use to find out or something? I really do not understand.
