H2O2 → H2O + O2
is this a balanced equation?
No, but you never should need to ask this question because you can figure it out yourself. Note:
There are two H atoms on the left from H2O2.There are two H atoms on the right from H2O. That's balanced for H atoms.
On the left there are two O atoms from the H2O2. On the right there are three O atoms; i.e., one from the H2O and two from the O2. O is not balanced. Therefore, the equation is not balanced because all of the atoms are not balanced.
