1) If the pressure on 56 mL vol. of a confined gas is increased from 720 mmHg to 760 mmHg while temperature increased from 25°C to 35°C. What is the final volume?    

2) Using the ideal gas law to calculate the mol of a gas at -26°C and .09 atm with a volume of 23mL

3) Define colligative properties and list four (4) of them:

4) In Ex: 12 there was a reaction between sulfamic acid and sodium nitrite which produced nitrogen, water and sodium bisulfate. (sulfamic acid is H2NSO3H(s) )

(A) Give the formula of the reactants

(B) Write the complete reaction 

5) The volume for the ideal perfect gas been determineto be 22.4133 L.                                                           Show how this value was calculated.

6) In the lab what does it mean when there is no water flowing from the Florence flask to the beaker and the entire solid has reacted? 

7) True or False: In Ex: 12 we could calculate the number of moles that where collected because one mole of nitrogen gas is produced for every mole of sulfamic acid.

8) When a solute is add to a pure solvent, what effects does the solute have on      freezing and boiling point of the solution?

9) What are the similarities between Boyle’s Law and Charles’s Law?

10) In Experiment # 13.

(A)  Why is Naphthalene used in this experiment instead of water? 

(B) Draw a graph to depict the freezing point depression of pure Naphthalene  

11). What is the mathematical equation of the rate equation expressed as?

12) What is the mathematical equation for the average rate of a reaction?

13) What is the expected freezing point of a solution that contains 25.0 g of fructose, C6H12O6, in 250.0 g of water? ( 1 mol C6H12O6 = 180 g, and Kf = 1.86oCm-1)

14) Ten moles of hydrogen gas at 0oC are forced into a cylinder with a volume of 300 mL. What is the pressure of the gas inside the cylinder, in atmosphere?

15) Identify the following laboratory  equipment, as
