What is the similarity between 0.6 M KI and 0.6 m KI ?

Molarity and molality are both used to express the concentration of a solution. The amount of solute is both expressed in moles.

Explanation:

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.
