  1. Semester exam final review game 1/7/2013 biochemistry

  2. Connect-4-around: Team 1 Red vs Team 2 blue 1 point per each set of 4 contacting rings in your team’s color 4 vertical 4 horizontal 4 diagonal

  3. Stoichiometry (ch 5) Unit Test Trial 2—Friday • Use: bingo—review of polyatomic ions and common acids and bases • Use this power point to practice Knowing numbers subatomic particles proton, neutron, electron in isotopes of an element and in ions versus neutral atoms Writing chemical formulas from names for ionic compounds and covalent compounds & writing names from formulas Knowing the polyatomic ions Finding molar masses of elements and compounds Knowing the seven diatomic elements

  4. Rules: Each question is an opportunity to place a disk Every student should have a whiteboard & marker and should attempt to answer every question. When the answer is projected, if one or both team mates has the correct answer, then the team can place a disk into the cylinder. If neither team mate is correct, then the team makes no move on that round. Max # sets 4 connections at end of class wins

  5. MnCO3 Name it

  6. manganese (II) carbonate MnCO3 Mn2+CO32- Mn2+2CO32-2 MnCO3 Name transition metal Since there are 2 nonmetals, look up the polyatomic ion Name the polyatomic ion Mn2+CO32-

  7. Name three of the seven diatomic elements.

  8. H2 • F2 • Cl2 • Br2 • I2 • O2 • N2

  9. What is the formula of sodium carbonate?

  10. Na2 CO3

  11. What is the molar mass of sodium carbonate?

  12. Na2 CO3 • 23+23+12+16+16+16= 106g

  13. What is the molar mass of iron (III) sulfate

  14. Fe2(SO4)3 • 55.5+55.5+ 3(32.1) + 12(16)=399.9 g/mole

  15. formula mass chlorine?

  16. 1 formula mass=1 molecule Cl2= 70.8 amu1 molar mass Cl2=2(35.5 g) =70.8 gRemember the 7 diatomic elements: H2 N2 O2 F2 Cl2 Br2 I2

  17. Name it NaCN

  18. Na1+CN1-NaCNSodium cyanidename metalname the polyatomic ion2 common polyatomic ions end in –ide----memorize these!Hydroxidecyanide

  19. Name it CH3O4

  20. All nonmetals, so its covalent CH3O4 i name each elementii change ending far right element to -ideiii add prefex for # each to allmono-1 di-2 tri-3 tetra-4 penta-5 hexa-6 hepta-7 octa-8 nona-9 deca-10iv drop mono- only if on far left element in the formula Carbon trihydrogen tetraoxide

  21. Write the formula for germanium acetate

  22. Germanium acetate Ge4+(C2H3O2)41-Ge(C2H3O2)4Ge is a metal in family 14, so oxidation #= 4+ acetate has oxidation # 1-

  23. How many moles O in 1 mole Germanium acetate? Ge(C2H3O2)4

  24. Write the Formula iron (III) sulfateiron symbol Fe

  25. iron (III) sulfate Fe2(SO4)3 Ox # Fe (III) 3+ Sulfate polyatomic ion 2- Sum( # atoms X ox # positive ion)+ ( # atoms X ox # negative ion) = charge of the compound Criss cross, parenthesis around sulfate to show that there are 3 of the polyatomic ions

  26. calculate the Molar mass of iron(III) carbonate

  27. Fe3+2(CO3)2-3Molar mass Fe2(CO3)3 Fe 2 x 55 g=110g C 3 x 12 g = 36g O 9 x 16 g=144g __________ Total 291 g

  28. Formula mass tin hydroxide

  29. Formula mass tin hydroxideSn4+OH 1-Sn(OH)4 118.7 + 4(16) + 4(1) = 186 amu

  30. Molar mass of sodium phosphate

  31. Molar mass of sodium phosphate Na1+PO43-Na3PO4= 3(23) g + 31g + 4(16)g =161 g

  32. Molar mass copper (I) nitrate
