Identify the diene and dienophile that will yield the given product in a Diels‑Alder reaction, and identify the second major product of the reaction, by dragging the appropriate structures to the boxes.

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
