Acommon demonstration in chemistry courses involves adding a tiny speck of manganese(iv) oxide to a concentrated hydrogen peroxide solution. hydrogen peroxide decomposes quite spectacularly under these conditions to produce oxygen gas and steam (water vapor). manganese(iv) oxide is a catalyst for the decomposition of hydrogen peroxide and is not consumed in the reaction. what are the coefficients in the balanced chemical equation for this reaction?
