  2. STATE SYMBOLS Label each state symbol (s) _________________________ (l) _________________________   (aq)_________________________ (g) _________________________

  3. BALANCE Balance each of the following KClO3   →  KCl   +  O2 Be2C   +    H2O   →   Be(OH)2     +   CH4 CO    +    O2    →     CO2

  4. BALANCE AND NAME Balance each equation, name the reaction type, and provide the word equation. HNO2 → H2O + N2O3 Al + Pb(NO3)2 → Al(NO3)3 + Pb CH3OH (methanol) + O2 H2O + CO2 UF6 + Sr(NO3)2→ SrF2 + U(NO3)6

  5. BALANCE AND NAME Write the balanced chemical reaction and name the reaction type. Chlorine + Lithium Iodide → Lithium Chloride + Iodine Phosphoric Acid + Magnesium hydroxide → magnesium phosphate + water Calcium Oxide + Water → Calcium Hydroxide

  6. COMPLETE THE REACTION Complete the double replacement reactions using names and formulas. Write state symbols. Provide complete and net ionic equations. Note: water is a liquid Ammonium Sulfide + Iron (II) Nitrate → ?   Sulfuric Acid + Potassium Hydroxide → ?

  7. PUT IT ALL TOGETHER Write the balanced equation with state symbols. Note reaction type. Will the reaction occur? (Note: refer to the “Activity Series of Metals in Aqueous Solution” reference sheet) Jane mixed some copper (II) sulfate solution with some iron nails. The iron nails disappeared and she was left with copper metal and an iron (II) Sulfate solution.

  8. PUT IT ALL TOGETHER Write the balanced equation and use state symbols. Which element is reduced and which element is oxidized? Holly mixed hydrogen and oxygen in a reaction and produced liquid water.

  9. PUT IT ALL TOGETHER Write the balanced equation. Name the reaction type. Write complete and net ionic equations. Robert Downey Jr. (Iron Man) had some solid iron (II) phosphate and reacted it with Hydrochloric acid solution. This reaction yielded liquid Iron (II) chloride and phosphoric acid solution.

  10. SHORT ANSWER • What is the difference between coefficients and subscripts? How are they similar? • What is the difference between solvent and solute? • What are spectator ions? • When is an element reduced? Oxidized? • How do you determine when a reaction will occur in a single replacement chemical reaction?
