h2o2 for teeth - Imagemakers
Is there a complete list of all the half equations for $\ce {H2O2}$ - both oxidation and reduction, in acidic and alkaline conditions? I've looked on the internet but can't seem to find a list.

The structure of $\ce {H2O2}$ is $\ce {H-O-O-H}$, and an $\ce {- O-O -}$ functional group is called a peroxide, by definition. The peroxide functional group is attached to a hydrogen atom, so.
The equations $ (1)$ and $ (21)$ shows that $\ce {H2O2}$ can undergo spontaneous self-oxidation-reduction, and is therefore, thermodynamically unstable. Accordingly, $\ce {H2O2}$.
Understanding the Context
Manganese dioxide catalyzes the decomposition of hydrogen peroxide to water and oxygen gas. But what are the intermediates in this catalyzed reaction?
There is a lot of confusion about the n-factor of hydrogen peroxide in its disproportionation into water and oxygen. $$\ce {2H2O2 -> 2H2O + O2}$$ Some sources (1,2) say n.
$\ce {H2O2}$ will homolytically cleave for form two $\ce {.OH}$ radicals. Radicals are very reactive and will start a chain reaction, but ultimately you will end up with water and oxygen products.

Key Insights
You take a certain volume of 3% $\ce {H2O2}$ and add water until the total volume is 100 mL. Because 3% $\ce {H2O2}$ is mostly water, the total volume will be very close to the sum of.
Like all other peroxides, hydrogen peroxide ($\ce {H2O2}$) also consists of a relatively weaker $\ce {O-O}$ bond, which is susceptible for light or heat. In the presence of light (the UV light.
Below is one way to write it that shows what the enzyme does and avoids the uncertainty of the details: $$\ce {E + H2O2 -> E-O + H2O}\tag {1}$$ $$\ce {E-O + H2O2 -> E-O2 + H2O}\tag.
