One atmosphere is ~equal to
760 mm Hg
When determining R at the conclusion of this experiment, pressure must be in _____ and temperature in ____
atmospheres, kelvin
The purpose of adjusting the water level in the Florence flask to equal the level of the liquid in the buret is
to make the pressure inside the buret equal to atmospheric pressure
Dalton's Law of Partial Pressures states that
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
The accepted value for the Ideal Gas Constant is
0.08205 L.atm/mol.K
The pressure of hydrogen gas contained in the buret is approximated by
Atmospheric pressure minus the vapor pressure of water at this temperature
The gas that is produced in this reaction is
hydrogen
At the conclusion of the reaction hydrogen is the only gas contained in the buret
false, the gases contained are hydrogen, gaseous water and air
In this experiment the pressure exerted by which of the gases contained in the buret cannot be measured or determined
air
The mass of aluminum chosen for this is experiment is determined by
the capacity of the buret
What is the approximate mass of aluminum used in this experiment
0.025g
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
6
The barometer is located
there isn't one in the laboratory but our TA will give us the value
While doing the experiment the buret is
inverted
Two gas laws are made use of in this experiment. They are
Ideal Gas and Daltons
The reagents used in this experiment are
aluminum, sodium hydroxide and water
The ~molarity of the sodium hydroxide used in this experiment is
1
The purpose of this experiment is to
determine ideal gas content
To convert temperature to Kelvin
oC + 273.15
