Excess copper reacts with 170. g of silver nitrate to produce copper (II) nitrate and silver. Determine the % yield of Cu(NO3)2 if the actual yield is 46.9g.

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.

can you attach the

the dissolution of polymer can be thermodynamically described in 2 steps.
