Good Morning! 04/18/23•Starter: Did you go through the
review?•Today we are going to…
–Go over the review.–Then take the test
On the test you will be given
•The Periodic Table•Polyatomic Ions table•Covalent Prefixes•Metals with Multiple charges
Chemical Bonding and Reactions

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

Section 9: Classifying the Reactions
•Zn + 2 HCl ZnCl2 + H2
•Single Replacement (Sr)
•CH4 + 2 O2 CO2 + 2 H2O
•Combustion (Cb)
•2 H2O2 2 H2O + O2
•Decomposition (D)
•CaSO4 +2NaC2H3O2Ca(C2H3O2)2+Na2SO4
•Double Replacment (Dr)
