Transfer of electrons Combination: 10 P (s) + 5 O 2 (g) ! Displacement: Zn (s) + 2 HCl (aq) ! 1. Add nitric acid, HNO 3 (aq) 2. Add sodium hydroxide, NaOH(aq) 3. Heat then filter 4. Add sulfuric acid, H 2 SO 4 (aq) 5. Add zinc, Zn(s), then decant the liquid Copper Cycle Experiment Important Categories of Reactions Combination Decomposition Displacement Exchange Your textbook : REDOX (reduction/oxidation) Precipitation Equilibrium Acid-base Subcategories to explore : NEXT UP: Getting quantitative! (Chapter 4) (Chapter 5) (Lab 3) Wrap-up points: Most reactions involve exchange of ions or electrons Ions combine in ratios that maintaining charge neutrality of products. Redox reactions involve exchange of electrons between reactants....
