Step 1
The water vapor is present because water molecules evaporate and mix with the gas. The total pressure of the gas collected is the sum of the partial pressure of the gas produced and the vapor pressure of water at that temperature. Show more…

5. Explain why it was necessary to perform a pressure-temperature experiment with only air in the flask before performing the vapor pressure experiment. Describe how the pressure-temperature data for air was used to determine the vapor pressure.

* What is the current atmospheric pressure if the water vapor in the air is 2.5%. and the partial pressure of the vapor is 19.4 mm Hg? * If unreacted zinc is left over at the conclusion of the experiment, what is the effect on the calculated molar volume? Will it be larger or smaller? --- Explain. * if 20 g of hydrogen peroxide is decomposed, how many Liters of oxygen gas are expected? * The hydrogen and oxygen generated in this experiment are real gases. How would you expect them to deviate from the ideal gas law? Explain the needed conditions for this change. * The yield of gas in one student group is 83.1%; if the theoretical amount of gaseous product is 43.1 mL, what is the actual volume of gas captured?
