HOMEWORK: Problems 14-20 on pages 285 & 286

Kinds of chemical reactions: 1.Synthesis A + B → AB

Kinds of chemical reactions: 2. Decomposition AB → A + B

Kinds of chemical reactions: 3.Single replacement A + BX → AX + B

Kinds of chemical reactions: 4.Double replacement AX + BY → AY + BX

Kinds of chemical reactions: 5. Combustion A + O 2 → AO AH + O 2 → AO + H 2 O

Kinds of chemical reactions: When will a replacement reaction happen?

Activity Series (page 288) Lithium Potassium Sodium Aluminum Zinc Nickel Lead Silver Gold

Activity Series (page 288) Lithium Potassium Sodium Aluminum Zinc Nickel Lead Silver Gold sodium + lead nitrate →

Activity Series (page 288) Lithium Potassium Sodium Aluminum Zinc Nickel Lead Silver Gold sodium + lead nitrate → sodium nitrate + lead (single replacement)

Activity Series (page 288) Lithium Potassium Sodium Aluminum Zinc Nickel Lead Silver Gold zinc + potassium nitrate →

Activity Series (page 288) Lithium Potassium Sodium Aluminum Zinc Nickel Lead Silver Gold zinc + potassium nitrate → no reaction

(s) = solid (l) = liquid (g) = gas (aq) = aqueous (dissolved in water) (in parentheses) A couple of other rules of thumb

(in parentheses) (II) or (III) = the charge on a metal ion Polyatomic ions can also be in parentheses. Nickel(II) hydroxide = Ni(OH) 2 A couple of other rules of thumb

Nonmetals, by themselves, usually form diatomic molecules N 2 O 2 S 2

Nonmetals, by themselves, usually form diatomic molecules. N 2 O 2 S 2 So does hydrogen. H 2 A couple of other rules of thumb

Metals, by themselves, are usually written as monatomic. Al Cu Na Pb A couple of other rules of thumb

When transition metals form ions, they can have different charges. The charge (called the “oxidation state”) is sometimes written in parentheses. Fe(II) Fe(III) A couple of other rules of thumb

Major Oxidation States can be found in the appendix on pages 914-916. A couple of other rules of thumb

HOMEWORK: Problems 14-20 on pages 285 & 286. When they say “write chemical equations,” they mean balanced equations.
