If a sample of 2.00 moles of nitric oxide gas was reacted with excess oxygen, how many moles of nitrogen dioxide gas would be produced.

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.

did anyone actually do this? like if anyone has submitted this i rly need .
