the diagram shows the different models of the atom that eventually led to the modern atomic theory. which model was proposed as a result of Rutherford scattering experiment where positive particles did not pass straight through a foil as expected

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.

give me abc and i will get it for u.
