The reaction and rate law for the gas-phase decomposition of dinitrogen pentaoxide are 2 N2O5(g) 4 NO2(g) + O2(g), rate = k[N2O5]. Which of the following can be considered a valid mechanism(s) for the reaction? N2O5(g) NO3(g) + NO2(g) [fast, reversible] NO2(g) + N2O5(g) 3NO2(g) + O(g) [slow] NO3(g) + O(g) NO2(g) + O2(g) [fast] 2N2O5(g) N4O10(g) [slow] N4O10(g) 4NO2(g) + O2(g) [fast] 2{ N2O5(g) NO3(g) + NO2(g) } [slow] 2{ NO3(g) NO2(g) + O(g) } [fast] 2O(g) O2(g) [fast] 2N2O5(g) 4NO2(g) + O2(g) Viewing Saved Work Revert to Last Response

answer; i do believe the correct answer is (river); /// good luck

it's c. elements are placed in rows based on how may valencies electrons have.

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.

it is a solid

explanation:
