Ionic crystals are typically brittle because distortion of the crystal lattice produces:- a) Flow of the electrons b) Ionization of same atoms

c) Inter ionic attractions d) Inter ionic repulsion. e) None.

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.
