How do you balance h202 - h2o o2?

To balance the equation for the decomposition of hydrogen peroxide (H₂O₂) into water (H₂O) and oxygen (O₂), start with the unbalanced equation: H₂O₂ → H₂O + O₂. Balancing it involves ensuring the number of each type of atom is equal on both sides. The balanced equation is 2 H₂O₂ → 2 H₂O + O₂, where you have 4 hydrogen atoms and 4 oxygen atoms on each side.
