  1. 12.1 Nitrogen and sulfur

    1. 12.1.1Lack of reactivity of nitrogen, using triple

      • Explain the lack of reactivity of nitrogen, using triple bond strength and lack of polarity

    2. 12.1.2And explain

      • Describe and explain:: (a) the basicity of ammonia, using the Brønsted–Lowry theory; (b) the structure of the ammonium ion and its formation by an acid–base reaction; (c) the displacement of ammonia from ammonium salts by an acid–base reaction

    3. 12.1.3NOx sources and catalytic removal

      • State/explain: the natural and man-made occurrences of oxides of nitrogen and their catalytic removal from the exhaust gases of internal combustion engines

    4. 12.1.4Atmospheric NOx and photochemical smog

      • Understand: atmospheric oxides of nitrogen (NO and NO 2) can react with unburned hydrocarbons to form peroxyacetyl nitrate, PAN, which is a component of photochemical smog

    5. 12.1.5Role of NO and NO2 in the formation of acid

      • Describe the role of NO and NO2 in the formation of acid rain both directly and in their catalytic role in the oxidation of atmospheric sulfur dioxide
