Hydrogen peroxide (H2O2) naturally reacts to produce water (H2O) and oxygen (O2). 2 H2O2 ⟶2 H2O + O2

When manganese (IV) oxide (MnO2) is mixed with H2O2the reaction rate increases and the same products are formed. What is the most likely function of MnO2in this chemical reaction?

Group of answer choices

catalyst

reactant

electron donor

limiting reagent

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
