Homework Answers
Answer 1
If water levels inside and outside are same, then it means pressure in tube is same as that of air pressure.
Answer 2
She gas is collected over water, other gas that will be present is water vapor.

3. Nitrogen gas was collected in a eudiometer during a chemistry experiment by displacement of water. When the levels of water inside and outside the eudiometer were adjusted to be the same, the volume of the collected gas was found to be 85.2 mL. The water temperature was 24°C and the barometric (atmospheric) pressure was found to be 764.0 mm Hg. What would be the volume of dry nitrogen gas at STP?

QUESTION 3 A student collected a sample of hydrogen gas in a eudiometer over a water bath to experimentally determine the value of the gas constant, R. Calculate the experimental value of Rif the pressure of the gas was 0.991 atm, the volume was 36.3 mL the temperature was 292 K and the sample contained 1.54 x 103 moles of gas.

A sample of hydrogen is collected over water at a temperature of 230C. The pressure inside the tube is determined to be 689 mmHg, and 12.10 mL of gas has been collected. What would the volume of collected hydrogen be at STP? a weird lab decided to use glycerin, a liquid with a density of 1.260 g/mL. If the water level inside the tube was 12.31 cm higher than outside the tube, and the atmospheric pressure measured 728 mmHg, what...

Imagine an artificial cell submerged in a beaker of water. There is an equal concentration of NaCl on either side of the cell membrane. The membrane is permeable to water. It also contains an artificial NaCl pump which can pump NaCl from inside the cell when power is connected (when the pump is off, the membrane is impermeable to NaCl). The pump is turned on and 50% of the NaCl in the cell moves to outside the cell. What happens?...

In the diagram below, one beaker contains pure water and the
other contains an equal volume of seawater. Seawater has various
salts dissolved in it. The beakers are sitting in a totally
enclosed chamber, and the outside temperature and pressure are held
constant. Identify the statements below about this situation that
are not correct.
Statements:
I. Water will be transferred from the pure water beaker to
the seawater beaker.
II. Water will be transferred from the seawater beaker to

F. Would your value for "R" in the last experiment have been higher, lower, or the same if: a) all the magnesium had not reacted. b) we did not account for water vapor pressure. c) we did not account for the water level difference. d) the hydrogen was actually hotter than the water bath. The procedure of this experiment is based on the chemical reaction between magnesium metal and hydrochloric acid to produce hydrogen gas. Mg + 2 HCI -...

Hydrogen gas was collected in a tube by water displacement like in your experiment, and adjusted to have pressure inside the tube equal to atmospheric pressure. If the barometer reads 743 mmHg, and the vapor pressure of water is 3 kPa at today's temperature, what is the partial pressure of hvdmpen in the tube?

Two massless, frictionless pistons are inside a horizontal tube opened at both ends. A 10-cm-long thread connects the pistons. The cross-sectional area of the tube is 20 cm2. The pressure and temperature of gas between the pistons and the outside air are the same and are equal to P = 1.0×105N/m2 and T = 23 ∘C. A.) At what temperature will the thread break if it breaks when the tension reaches 33 N ?
