1. Review: Single Displacement Rxns A + BC  AC + B A more reactive element will “kick out” a less reactive one. Use the reactivity series to predict whether the rxn will occur.

2. Reactivity Series Metals – metals to the left are more reactive Li K Ba Ca Na Mg Al Zn Fe Ni Sn Pb H Cu Hg Ag Au Halogens – halogens in the upper left are more reactive than those below FClBrI

3. Rxn of Metals with Acid Reactivity Series is used to predict reactions with weak acids Metals to the left of H react to produce H 2 gas Li K Ba Ca Na Mg Al Zn Fe Ni Sn Pb H Cu Hg Ag Au React with acid No Rxn

4. Reaction with acid to produce H 2 gas Zn (s) + 2HCl (aq)  ZnCl 2(aq) + H 2(g) Practice: Predict the products and balance Solid magnesium + sulfuric acid (H 2 SO 4 ) 

5. Predicting Rxns of metals with H 2 O The first 5 metals on the left of the reactivity series will react with water to form a base (metal + OH - ) Li K Ba Ca Na Mg Al Zn Fe Ni Sn Pb H Cu Hg Ag Au React w/ H 2 O

6. Examples 2K (s) + 2H 2 O (l)  2KOH (aq) + H 2(g) Predict the products and balance the equation: Calcium and water 
