If 22.5 L of nitrogen gas at 3.5 atm are compressed to 0.8 atm at constant temperature, what is the new volume? Assume amount of gas remains constant.

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.
