Explain how it is possible for organisms to play more than role an why it is important

oh it is true if thats what you are asking

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.

the ratio of the conjugate base to the acid required to attain the desired ph.
