Sodium Peroxoborate reacting with Sulfuric Acid and Potassium Permanganate
Well $\ce{KMnO4} $ and $\ce{H2O2}$ react as follows:

$$\ce{2KMnO4 +3H2O2 -&gt; 2MnO2  + 2KOH + 2H2O + 3O2}$$ 

Adding the two reactions together I get:

$$\ce{Na2[B2(O2)2(OH)4] + H2SO4 + 2KMnO4 + H2O2 -&gt;Na2SO4 + 2H3BO3 + 3O2 + 2MnO2 + 2KOH}$$
