Ahalf-life is the time required for one-half of the atoms of a radioisotope to emit radiation and decay to products. what value in this lab represents one half-life for the process of flipping coins? trial number of flips number of heads none of the above.

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.
