the reaction 2n2o5(g) → 2n2o4(g) + o2(g) obeys the rate law rate k[n2o5], in which the specific rate constant is 0.00840 s-1 at a certain temperature. a. if 2.50 moles of n2o5 were placed in a 5.00-liter container at that temperature, how many moles of n2o5 would remain after 1.00 minute? b. how long would it take for 90% of the original n2o5 to react?

Your answer to this question is true. hope this .

The correct answer is b, social stratification is needed for a society to exist. marxist theory regarding social stratification is that due to the differing economic capacities among people in society, a natural separation occurs between those that own the means of production and those that sell their labour in the production chain.
