Whats the net ionic equation for the decomposition of hydrogen peroxide (H202)?  I know that it decomposes into water and O2 but is H202->H20+O2 the net ionic or does the H2 and O2 split up to be H2 + O2 -> H20+O2 and if so is the net ionic then just H2->H20??

in an ionic equation reactants and products in aqueous form are split up into their ions, hence 2H+ + 2O- would be more appropriate than H2 + O2.

im not so sure about that, i dont even know whether it dissociates into ions.

to me i'll just have wrote the balanced form, 2H2O2 --> 2H2O + O2

there is no such net ionic equation.

however, the decomposition of h2o2 can broken down into 2 steps.

oxidation: H2O2 -> H2O + [

• ]

reduction: H2O2 + [

• ] -> H2O + O2

net equation: 2H2O2 -> 2H2O + O2
