1. CHEMICAL REACTIONS LEVEL 1 – CHAPTERS 10 AND 20 Reactant A Reactant B Product(s)

2. CHEMICAL REACTIONS: Reactants → products Symbols: (s) (l) (g) (aq) Δ Catalyst Descriptive sentence → Word Equation (Names → Formulas) → Chemical Equation

3. BALANCING CHEMICAL EQUATIONS Examples:

4. 5 TYPES OF CHEMICAL REACTIONS: 1.Combination (Synthesis): only 1 product 2.Decomposition: only 1 reactant

5. 3. Single-Replacement Activity Series of Metals Reactivity Trend in Periodic Table for Halogens

6. 4. Double-Replacement

7. 5. Combustion Complete: Incomplete:

8. NET IONIC:

10. WILL SOMETHING PRECIPITATE? Always soluble (aq): ionic compounds containing… group 1 alkali metals, ammonium, nitrate, chlorate Soluble EXCEPT: chloride = soluble, unless containing Pb, Ag, Hg “the big three” sulfate = soluble, unless containing Pb, Ag, Hg, Ca, Sr, Ba NOT soluble (unless meets conditions above): carbonate, phosphate, chromate, sulfide, hydroxide
