Nitrogen forms a surprising number of compounds with oxygen. A number of these, often given the collective symbol NOx (for "nitrogen + x oxygens") are serious contributors to air pollution. They can often be interconverted, sometimes by reaction with oxygen or ozone (O3) in the air. An atmospheric scientist decides to study the reaction between nitrogen trioxide and nitrogen monoxide that produces nitrogen dioxide. He fills a stainless steel reaction chamber with 6.3 atm of nitrogen trioxide gas and 9.1...
