Question 1 - 10

• What is the formula to convert from MOLES to GRAMS:

• Moles Grams

Answer 1 – 10

• # moles X (molar mass/1 mole) = mass (g)

Question 1 - 20

• What is the formula to convert from GRAMS to MOLES

• Grams moles

Answer 1 – 20

• Mass (g) X (1mole/molar mass) = # of moles

Question 1 - 30

• What is the mass of one mole of water?

Answer 1 – 30

• 18 grams!

• Work: 2(2) + 16 = 18 grams

Question 1 - 40

• How many moles of propane C3H8 are in 250.00g of propane?

Answer 1 – 40

• 5.7 moles

– Work: 250g X (1 mol/44 g) = 5.7 moles

Answer 3 – 50

• A special type of oxidation that hydrocarbons go through

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

Answer 4 – 10

• Nonrenewable

• Petroleum

Question 4 - 20

Why is crude oil superheated in the refinery process?

Answer 4 – 20

The hydrocarbons in the crude oil can be separated based on their boiling point.

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

Answer 4 – 30

• Small hydrocarbon is characterized by a low boiling point

• Large hydrocarbon is characterized by a high boiling point
