At the beginning of an experiment, the concentration of nitrogen dioxide in a reaction vessel was 0.1103 mol/l. after 65.0 s, the concentration decreased to 0.1076 mol/l. what is the average rate of decomposition of no2 during this time interval, in mol/(l ∙ s)?

-4.15*

Explanation:

Average rate            =

The rate is negative because it is a decomposition and our focus is the reactant which is depleting.

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.
