Calculate the average rate of decomposition of NH4NO2 by the reaction 2NH4O5(aq) --> N2(g) H2O(g) at the following time interval. At time 250 s, the concentration of NH4NO2 is 4.12 M. At time 330 s, the concentration of NH4NO2 is 1.48 M

Explanation:

Hello!

In this case, since the average rate of reaction is computed as a change given by:

In such a way, given the concentrations at the specified times, we plug them in to obtain:

Whose negative sign means the concentration decreased due to the decomposition.

Best regards!

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.

what is the question here. i think you messed up.
