H 2 O 2 H 2 O + O 2

2 h2 o2  =  2 h20 + o2   

   if you are trying to balance the equation for the breakdown of hydrogen peroxide to water and oxygen

$H_2O_2\rightarrow H_2O+O_2\\ 2H_2O_2\rightarrow 2H_2O + O_2$

Does that mean every 2 molecules of hydrogen peroxide will break down into 2 molucules of water and 1 molecule of oxygen gas?

Sorry for only knowing how to balance an equation LOL
