Section 2: Writing ionic compounds. Practice

•Calcium Oxide = CaO Both 2•Copper (I) Iodide = CuI Both 1•Lithium Bromide = LiBr Both 1

•Magnesium Phosphide = Mg3P2

•Mg is +2, P is -3

Section 3: Naming ionic compounds:

•CrCl3 = Chromium (III) Chloride

–Chromium (II) Chloride is CrCl2•CuBr = Copper (I) Bromide

–Copper (II) Bromide is CuBr2

•FeO = Iron (II) Oxide

–Iron (III) Oxide is Fe2O3

•MgS = Magnesium Sulfide

Section 4 & 5: Writing formulas and naming them.

• K and PO4 = K3PO4

• Potassium Phosphate

• Mg and SO4 = MgSO4

• Magnesium Sulfate

• NH4 and SO4 = (NH4)2SO4

• Ammonium Sulfate• Na and OH = NaOH• Sodium Hydroxide

Section 6: Naming covalent compounds. Remember the

prefixes and write the following examples:

•N2O

•N2O5

•CBr4

•CS2

=Dinitrogen Monoxide=Dinitrogen Pentaoxide=Carbon Tetrabromide=Carbon DiSulfide

Section 7: Naming covalent compounds. Remember the

prefixes and write the following examples:

• Tetracarbon Octobromide

• Trinitrogen hexasulfide

• Pentaphosphorus heptaoxide

• Sulfur Diodide

=C4Br8

=N3S6

=P5O7

=SI2

Section 8: Balancing Reactions

•Zn + HCl ZnCl2 + H2

•CH4 + O2 CO2 + H2O

• H2O2 H2O + O2

•CaSO4 + NaC2H3O2 Ca(C2H3O2)2 + Na2SO4
