Along glass capillary tube, of diameter 0.01 cm, is in contact with water at one end and dry air at the other. water vapor evaporates at the wet end within the capillary, and the vapor diffuses through the capillary toward the dry end. how long is required for 1.0 g of water to evaporate through this system? the vapor pressure of water is 16.48 mmhg at 19 c, the temperature at which the entire system is maintained. take the diffusivity of water vapor in air at 19 c to be 0.298 cm2/s, and assume that the dry air is at a pressure of 760 mmhg. assume that the distance from the wet interface within the capillary to the dry end is always 10 cm.

Amount of liquid measured in l or lm

13. calculate the initial concentration (before precipitation) of carbonate ions after the addition of each 0.05 ml of solution b to the 1.00 l beaker of solution a. divide the work among group members and write the answers in the table in model 3. assume the volume change as solution b is added is negligible. 14. notice the initial concentrations of zn2+ - and cu2+ in the table in model 3. a. explain how these were obtained from the data in model 2. b. as solution b is added and precipitates form, do these initial concentrations change? 15. use the data in model 2 to indicate the presence of precipitate (either znco3 or cuco3) after each 0.05 ml addition of solution b in model 3. 16. use the initial concentrations of carbonate ions and zinc ions to calculate the reaction quotient, qsp for the zinc carbonate scenarios in model 3. divide the work among group members and write the answers in the table in model 3. 17. use the initial concentrations of carbonate ion and copper(ii) ions to calculate the qsp for the copper(ii) carbonate scenarios in model 3. divide the work among group members and write the answers in the table in model 3.
