How does the structure of covalent bond affect the structure of covalent compounds

A covalent bond holds two atoms close together because electrons in their outermost orbitals are shared by both atoms.

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.
