Instructions for Side by Side Printing
  1. Print the notecards
  2. Fold each page in half along the solid vertical line
  3. Cut out the notecards by cutting along each horizontal dotted line
  4. Optional: Glue, tape or staple the ends of each notecard together
  1. Verify Front of pages is selected for Viewing and print the front of the notecards
  2. Select Back of pages for Viewing and print the back of the notecards
    NOTE: Since the back of the pages are printed in reverse order (last page is printed first), keep the pages in the same order as they were after Step 1. Also, be sure to feed the pages in the same direction as you did in Step 1.
  3. Cut out the notecards by cutting along each horizontal and vertical dotted line
To print: Ctrl+PPrint as a list

19 notecards = 5 pages (4 cards per page)

Lab 5

front 1

One atmosphere is ~equal to

back 1

760 mm Hg

front 2

When determining R at the conclusion of this experiment, pressure must be in _____ and temperature in ____

back 2

atmospheres, kelvin

front 3

The purpose of adjusting the water level in the Florence flask to equal the level of the liquid in the buret is

back 3

to make the pressure inside the buret equal to atmospheric pressure

front 4

Dalton's Law of Partial Pressures states that

back 4

the total pressure exerted by a mixture of gases is equal to the sum of the pressures exerted by the individual components in the mixture

front 5

The accepted value for the Ideal Gas Constant is

back 5

0.08205 L.atm/mol.K

front 6

The pressure of hydrogen gas contained in the buret is approximated by

back 6

Atmospheric pressure minus the vapor pressure of water at this temperature

front 7

The gas that is produced in this reaction is

back 7

hydrogen

front 8

At the conclusion of the reaction hydrogen is the only gas contained in the buret

back 8

false, the gases contained are hydrogen, gaseous water and air

front 9

In this experiment the pressure exerted by which of the gases contained in the buret cannot be measured or determined

back 9

air

front 10

The mass of aluminum chosen for this is experiment is determined by

What is the approximate mass of aluminum used in this experiment

back 11

0.025g

front 12

When the chemical equation
Al(s) + NaOH(aq) + H2O(l) = NaAl(OH)4(aq) + H2(g)
is balanced, the stoichiometric coefficient in front of the water is
