No, the formulas H2O and H2O2 are not the same. H2O represents water, while H2O2 represents hydrogen peroxide. Water has two hydrogen atoms and one oxygen atom, while hydrogen peroxide has two hydrogen atoms and two oxygen atoms.
Nope - water is H2O... H2O2 is Hydrogen Peroxide.
Because peroxide will yield H202 upon reaction with acid while Dioxide will not yield H202 with acid
