Our teacher showed us this method but he went over it so fast that i didn't really understand a part of the process. He said that the first step he wanted us to do was to put a -2 over every oxygen (O) in the equation and to put a +1 over every hydrogen (H) in the equation so I do that but how exactly did he get that and how do you get it for any other element that is in the equation? That's what i really need help with so if you can help me. Thank you so much! :]
