  1. Review NOMENCLATURE EOC Review Day 2

  2. Nomenclature • Steps Naming compounds • Acid? If acid use rules for naming acids • Ionic /Covalent? If covalent use prefixes. • Ionic- binary/ternary? If ternary, use polyatomic ion sheet. Do not change name of polyatomic ions. • Check for transition metals. If transition metals use Roman numerals to indicate charge. Determine charge from formula.

  3. Assignment: Rally Coach • Steps for each compound: 1. Copy the formula 2. Put the formula in words 3. Calculate the molar mass of each compound ( mass of 1 mole)

  4. Examples 3MnO2 • 3 formula units of manganese (IV) oxide • Molar mass =(1x54.938)+ (2x 15.99) =86.936 g 5SO2 • 5 molecules of sulfur dioxide • Molar mass = (1x32.066)+(2x15.999)=64.064g

  5. Problems (Rally Coach) • 2ZnCl2 9. 2AlCl3 17. 8KCr2O7 • 1HgO 10. 3Fe2O3 18. 2Rb2CO3 • 8SiO2 11.9Al2(SO4)3 19. 1CoCl2 • 4NaOH 12.5NH4OH 20. 6Ni2O • 2CO2 13.2H2O 21. 8CrN • 6H3PO4 14. 3NaCH3COO22. 7SO3 • 8Na2O 15. 5Fe(OH)3   23. 3SF3 • 7NaCl 16.9Mg3N2 24. 3SrO
