Unformatted text preview: C h a p t e r 4 Reactions in Aqueous Solution Chemistry, 5 th Edition McMurry/Fay 2 Some Interesting Chemical Reactions 1. Production of Smog N 2 + O 2 + heat → 2 NO 2 NO + O 2 → 2 NO 2 (brown gas) 2. The Greenhouse Effect 2 C 8 H 18 + 25 O 2 → 18 H 2 O + 16 CO 2 CO 2 transmits visible light but absorbs heat 3 Some Interesting Chemical Reactions 3. Reduction of Iron Ore Fe 2 O 3 + 3 CO → 2 Fe + 3 CO 2 4. Depletion of Ozone O 3 + uv rays → O 2 + O CF 2 Cl 2 + O 3 → O 2 + O 4 Some Interesting Chemical Reactions 5. Photosynthesis 6 CO 2 + 6 H 2 O → C 6 H 12 O 6 + 6 O 2 6. Acid Rain S + O 2 + heat → SO 2 SO 2 + H 2 O → H 2 SO 3 (acid) 5 Types of Chemical Reactions • Precipitation Reactions: The chemical reaction that occurs when two solutions are mixed and a solid precipitate is formed. AgNO 3 (aq) + NaCl (aq) → NaNO 3 (aq) + AgCl (s) 6 Precipitation Reactions • Net Ionic Equations: Break the reaction down into aqueous ions and precipitates. Eliminates “spectator ions,” thus simplifying the equation.“spectator ions,” thus simplifying the equation....
