Archie wanted to find out if Jughead's crown was made of pure gold (Betty and Veronica were able to remove the crown while he was sleeping and brought it to Archie.) First, he measured its mass: 432.0g. Next he measured its mass when the crown was underwater: 352 g. What is the volume of the crown?

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.
