Indicate whether the following experimental mistake will increase, decrease, or have no effect on the calculated value of R. In adjusting the final water level after the O2 was produced, the student adjusted the levels to the bottom of the water in the beaker and the top of the water in the flask (rather than correctly the top of each). See image below. Select ALL of the correct answers. Delivery Tubing Beaker Florence Flask O a. The value of the calculated R is low. O b. Water flows from the flask to the beaker. O c. The volume measured from the beaker is unaffected. d. The value of the calculated R is high. O e. The volume measured from the beaker is low. f. Water does not flow under these circumstances. g. Water flows from the beaker to the flask. O h. The value of R is unaffected. O i. The volume measured from the beaker is high. O O O 0 00000

Indicate whether the following experimental mistake will increase, decrease, or have no effect on the calculated value of R. A student completed the experiment without waiting for the test tube to cool after heating. Select ALL of the correct answers. a. If the system has not cooled, the gas is expanded, and its volume is high. b. The measured temperature is room temperature. c. The volume measured from the beaker will be low. d. The gas does not have to cool to room temperature before measuring the volume. e. The volume measured from the beaker will be high. f. The volume measured from the beaker will have no effect. g. All measurements should be made at the same temperature. h. Allowing the system to cool has no effect. i. The calculated value of R is high. j. The calculated value of R is low. k. If the system has not cooled, the gas is condensed, and its volume is low. O1. The calculated value of R is unaffected.
