Concept explainers
Dinitrogen monoxide, N2O (commonly called nitrous oxide), is prepared by the careful decomposition of ammonium nitrate and is used as an oxidizing agent in rocket engines as well as a weak general anesthetic (where you may know it as “laughing gas”). However, it is also known to be a powerful greenhouse gas. In a Science magazine article, it was stated that “Human activities may be causing an unprecedented rise in the terrestrial N2O source. Marine N2O production may also rise substantially as result of eutrophication, warming and ocean acidification.” [L. A. Codispoti, Science, Vol. 327, pp. 1339-1340, 2010.]
The powerful greenhouse gas N2O is used as a propellant in cans of instant whipped cream.
- (a) Draw a Lewis electron dot structure for N2O, and specify the formal charge on each atom and the molecular geometry.
- (b) The atom connections are N—N—O. Why is the connection N—O—N not likely?
The highest N2O concentration observed in the ocean is about 800 nM (nanomolar). At this concentration, what is the mass of N2O per liter?
