Consider the following reaction: 2 N2O(g) → 2 N2(g)+O2(g)
b. In the first 12.0 s of the reaction, 1.5×10−2 mol of O2 is produced in a reaction vessel with a volume of 0.400 L . What is the average rate of the reaction over this time interval?
c. Predict the rate of change in the concentration of N2O over this time interval. In other words, what is Δ[N2O]Δt?

Read these sentences from the text. near the equator, the tropics receive the most rain on a consistent basis. as a result, the fresh water falling into the ocean decrease the salinity of the surface water in that region. [. .] . . as the salt content of sea water increases, so does its density. what can you infer about how rain affects the density of surface water near the equator?
