  2. Question 1 - 10 • What is the formula to convert from MOLES to GRAMS: • Moles  Grams

  3. Answer 1 – 10 • # moles X (molar mass/1 mole) = mass (g)

  4. Question 1 - 20 • What is the formula to convert from GRAMS to MOLES • Grams  moles

  5. Answer 1 – 20 • Mass (g) X (1mole/molar mass) = # of moles

  6. Question 1 - 30 • What is the mass of one mole of water?

  7. Answer 1 – 30 • 18 grams! • Work: 2(2) + 16 = 18 grams

  8. Question 1 - 40 • How many moles of propane C3H8 are in 250.00g of propane?

  9. Answer 1 – 40 • 5.7 moles • Work: 250g X (1 mol/44 g) = 5.7 moles

  10. Question 1 - 50 • Calculate the molar mass for (NH4)2SO4

  11. Answer 1 – 50 • 132.1 g/mol

  12. Question 2 - 10 • Ms. Musta named her newborn……?

  13. Answer 2 – 10 • Exyn

  14. Question 2 - 20 • Ms. Y’s full last name (must pronounce it correctly) is…….

  15. Answer 2 – 20 • Ms. Yackanin

  16. Question 2 - 30 • Your new sub will be starting next week. Her name is….

  17. Answer 2 – 30 • Ms. Bell!

  18. Question 2 - 40 • Where can you find any and all resources to do well on this test?

  19. Answer 2 – 40 • On Ms. Musta’s website!

  20. Question 2 - 50 • Where (what school) and what grade did Ms. Yackanin teach last semester?

  21. Answer 2 – 50 • Mount Elden Middle School • 8th grade

  22. Question 3 - 10 • What is a mole?? • Does a mole account for a large or small amount?

  23. Answer 3 – 10 • It is a counting unit for chemistry. • It is a large (huge!) amount

  24. Question 3 - 20 • What are hydrocarbons?

  25. Answer 3 – 20 • Molecular compounds that contain the elements HYDROGEN and CARBON only

  26. Question 3 - 30 • What is an isomer?

  27. Answer 3 – 30 • It is a compound with the same MOLECULAR structure as another but with a DIFFERENT structure. • Example:

  28. Question 3 - 40 • A catalyst does what? • A basic example of a catalyst is when we introduce an ________ into a reaction.

  29. Answer 3 – 40 • Changes the rate of the reaction • An enzyme

  30. Question 3 - 50 • Combustion is?

  31. Answer 3 – 50 • A special type of oxidation that hydrocarbons go through

  32. Question 4 - 10 • Is petroleum a renewable or nonrenewable resources? • Crude oil is the same thing as: • Normal oil and gases • Fossils • Petroleum • Coal • Gasoline

  33. Answer 4 – 10 • Nonrenewable • Petroleum

  34. Question 4 - 20 Why is crude oil superheated in the refinery process?

  35. Answer 4 – 20 The hydrocarbons in the crude oil can be separated based on their boiling point.

  36. Question 4 - 30 • When superheated (to boiling point), small hydrocarbon would have a __________ boiling point where as a larger hydrocarbon would have _________ boiling point. • Low • High

  37. Answer 4 – 30 • Small hydrocarbon is characterized by a low boiling point • Large hydrocarbon is characterized by a high boiling point

  38. Question 4 - 40 • We learned that petroleum in the refining process produces several distinctive mixtures called ______________ ? • Hint: We learned about 7 of those last week

  39. Answer 4 – 40 • Fraction

  40. Question 4 - 50 • A petroleum is defined as what?

  41. Answer 4 – 50 • A collection of hydrocarbons of similar length found in the crude oil

  42. Question 5 - 10 • What does the hydrotreating process remove from the hydrocarbon fractions?

  43. Answer 5 – 10 • It removes impurities: • Examples are sulfur, metals, and nitrogen

  44. Question 5 - 20 • In naming organic compounds, an alkane is what??

  45. Answer 5 – 20 • Compounds with a single bond between carbon atoms

  46. Question 5 - 30 • In naming organic compounds, what is an alkene?

  47. Answer 5 – 30 • Compounds with atleast one double bond between carbon atoms

  48. Question 5 - 40 • What do we mean that a hydrocarbon can go through combustion? • Why do hydrocarbons make good fuels?

  49. Answer 5 – 40 • We are burning it • They produce a lot of energy when combusted
