A 250 mL flask contains air at 1.061 atm and 20.3 °C. 5 mL of ethanol is added, the flask is immediately sealed and then warmed to 93.3 °C, during which time a small amount of the ethanol vaporizes. The final pressure in the flask (stabilized at 93.3 °C) is 2.833 atm. (Assume that the head space volume of gas in the flask remains constant.) a. What is the partial pressure of air, in the flask at 93.3 °C? 1homework...

Problem 17.39 A 3700 mL flask is initially open in a room containing air at 1.00 atm and 20 ∘C. The flask is then closed and immersed in boiling water. When the air in the flask has reached thermodynamic equilibrium, the flask is opened and air is allowed to escape. The flask is then closed and cooled back to 20 ∘C. Part A: Find the maximum pressure reached in the flask. Express your answer with the appropriate units. p_max =...

For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2
For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2....the problem is that if I don't boil it for that long and (30 min) b/c of not enough time but I put the water I boiled for 1/2 hr aproximately into a NaOH bottle with a CO2 absorber and stored it there for a few days. I would assume that I would have to boil the water again...but...
