  1. Review Game for 12/18 APC

  2. 1 • Identify the respective proton number, neutron number, and number of electrons found in

  3. 2 • A reaction occurs between sodium carbonate and hydrochloric acid producing sodium chloride, carbon dioxide, and water. The correct set of coefficients, respectively, for the balanced reaction is ___.

  4. 3 • Which type of substance is often easily separated into its components by simple techniques such as filtering or decanting?

  5. 4 • Copper has a density of 8.960 g/cm3. A block of copper that measures 1.01 cm x 4.01 cm x 1.50 cm, what is the mass of the copper?

  6. 5 • What are the four quantum numbers for the outermost electrons in a phosphorus atom?

  7. 6 Consider three 1-L flasks at STP. Flask A contains NH3 gas, flask B contains NO2 gas, and flask C contains N2 gas. • Which contains the largest number of molecules? • In which flask would the molecules have the greatest kinetic energy?

  8. 7 Consider the balanced equation: 2H2+ O2 2H2O • What volume of oxygen in liters must be available at STP to allow 6.00 g of hydrogen to react and form water?

  9. 8 • The oxidation number of the chromium atom in the dichromate ion (Cr2O72-) is___.

  10. 9 • What conditions with temperature and pressure will cause an ideal gas to act like a real gas?

  11. 10 • Which quantum number describes the shape of an orbital?

  12. 11 • What is the relationship between bond order and bond length?

  13. 12 • Which elements have an electronegativity 3 or above?

  14. 13 • Resonance structures differ by __.

  15. The Answers

  16. 1 • Protons = 26, neutrons = 30, and electrons = 26

  17. 2 Na2CO3 + 2HCl  2NaCl + CO2 + H2O • 1, 2, 2, 1, 1

  18. 3 • Heterogeneous mixture

  19. 4 • 54.4 g

  20. 5 • (3, 1, -1, ½)

  21. 6 Consider three 1-L flasks at STP. Flask A contains NH3 gas, flask B contains NO2 gas, and flask C contains N2 gas. • All contain the same number of molecules • All have the same kinetic energy because they are at the same temp

  22. 7 Consider the balanced equation: 2H2+ O2 2H2O • 33.3 L

  23. 8 • The oxidation number of the chromium atom in the dichromate ion (Cr2O72-) is +6.

  24. 9 • High pressure or low temperature. • Both will cause the volume to be low which in turn will cause the particles to be very close together.

  25. 10 • Azimuthal (l)

  26. 11 • As bond order increases, bond length decreases

  27. 12 • N, O, F, Cl

  28. 13 • Resonance structures differ by the arrangement of the electrons.
