Buff, Chemistry. It was so long ago ...
Can be 2(H2O2) -->2(H20) + 1(O2) ?? I think (but not sure) you should always find the odd one and make it double. Here it is oxigen, you need 3 (1 in H20 + 2 in O2) So you must make the one double (because you have 02) so 2(H2O) + 1(O2)--> 2(H202) but I ahve a wacky memory, it can be wrong. saludos

ok I will see if that's correct. I don't think it's necessary to put a 1 in front of O2. It'll still be O2

First write the equation as you did,
H2O2 -> H2O + O2 Then notice that you need one more oxygen to get that diatomic O2. Temporarily put 1/2 in front of O2. Then multiply everything by 2 to get rid of that fraction. The final balanced equation will look like this, 2H2O2 -> 2H2O + O2 HERE'S ALINK TO A TUTORIAL http://www.sky-web.net/science/balancing... GOOD LUCK!!!!!!!
