ON YOUR WHITE BOARDS
Write and balance the reaction
between zinc and oxygen
2Zn(s) + O2(g) 2ZnO(s)
ON YOUR WHITE BOARDS
Write the reaction between zinc oxide and nickel
Remember what do you need to check when you write single replacement reactions
ANSWER
ZnO + Ni No Reaction
Zinc is more active than nickel on the Activity
Series so nickel cannot replace zinc in the reaction
ACID-BASE REACTIONS
How can you tell if a compound is an acid
bull The compound begins with hydrogen ( has H+)
How can you tell if a compound is a base
bull The compound has the polyatomic ion hydroxide (has OH - )
How to identify an acid-base reaction
Acid + Base rarr Salt + Water
ACID-BASE EXAMPLE
HCl + Mg(OH)2 rarr MgCl2 + H2O
Acid because
hydrogen
Base because
hydroxideHCl is
stomach acid
Mg(OH)2 is milk of
magnesia which is an
antacid (neutralizes the
stomach acid)
Salt because ionic (metal and
nonmetal)
PRECIPITATE REACTIONS
Precipitate = insoluble
bull Determine using solubility chart
Is a precipitate considered soluble or insoluble
Where would you look to see if a precipitate will be formed
bull The solubility chart in your reference materials
Would NH4OH be soluble or insoluble
1 Find the anion on the chart
2 Is the anion in the soluble or insoluble
box
3 Is the anion with any of the
exceptions
4 Is it soluble or insoluble
Insoluble
Yes
OXIDATION REDUCTION
REACTIONS
Oxidationndash loss of electrons
Reduction- gain of electrons
In the following video watch for what is being oxidized what is
being reduced How can you tell the difference

Rules
bull Track electrons by assigning oxidation numbers (charge)
bull For atoms in their elemental form the oxidation number is 0
bull For ions the oxidation number is equal to their charge
bull For single hydrogen the number is usually +1
bull For oxygen the number is usually -2
bull The sum of the oxidation number of all the atoms in the molecule
or ion is equal to its total charge

Rules
bull Track electrons by assigning oxidation numbers (charge)
bull For atoms in their elemental form the oxidation number is 0
bull For ions the oxidation number is equal to their charge
bull For single hydrogen the number is usually +1
bull For oxygen the number is usually -2
bull The sum of the oxidation number of all the atoms in the molecule
or ion is equal to its total charge

ACID-BASE EXAMPLE
HCl + Mg(OH)2 rarr MgCl2 + H2O
Acid because
hydrogen
Base because
hydroxideHCl is
stomach acid
Mg(OH)2 is milk of
magnesia which is an
antacid (neutralizes the
stomach acid)
Salt because ionic (metal and
nonmetal)
PRECIPITATE REACTIONS
Precipitate = insoluble
bull Determine using solubility chart
Is a precipitate considered soluble or insoluble
Where would you look to see if a precipitate will be formed
bull The solubility chart in your reference materials
Would NH4OH be soluble or insoluble
1 Find the anion on the chart
2 Is the anion in the soluble or insoluble
box
3 Is the anion with any of the
exceptions
4 Is it soluble or insoluble
Insoluble
Yes
OXIDATION REDUCTION
