Find the volume of 85g of O2 at 25°c
and 104.5kpa.( R=8.315dm. kpa/mol. k​

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.

b) nuclear ive learned that in a pedtrodic table
