What is the decomposition of hydrogen peroxide to generate oxygen?

Answer 1

#2 color(white)(l) "H"_2 "O"_2 (aq) stackrel("MnO"_2)(to) 2color(white)(l) "H"_2 "O" (l) + "O"_2 (g)#

Two moles of hydrogen peroxide #"H"_2 "O"_2# decomposes to produce two moles of water #"H"_2 "O"# and one mole of oxygen gas #"O"_2 (g)#, which then bubbles off.

Both heating and the presence of a heterolytic catalyst #"MnO"_2#- which provides an activation site for the reaction to proceed- can speed up this process.

Hydrogen peroxide must break down into water (H2O) and oxygen (O2) gas in order to produce oxygen. Various substances, such as manganese dioxide (MnO2) or the enzyme catalase, can catalyze this reaction, which has the following chemical equation: 2 H2O2 (aq) -> 2 H2O (l) + O2 (g)

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
