A 2.0g of metal at 50.0°C is placed in a calorimeter containing 100.0g of water at 25.0°C. The final temperature is 28.0°C. What is the specific heat of the metal?

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.
