A3.25-g sample of sodium hydrogen carbonate reacts completely with sulfuric acid in a time of 20 s. express the average rate of reaction as b. mass of h2so4 consumed per second c. amount of h2so4 consumed per second d. amount of co2 produced per second

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.

the answers would be

the first one and the second one
