Correct for the water vapor present in the wet dry ice experiment and compare and compare with the mean value for the dry ice experiment. Does the presence of water vapor affect the result? Explain why it does or does not have a large affect on the value obtained.
the 20 ml of water added to the erlenmeyer flask is to be previously boiled deionized water. Since water does absorb CO2 from the atmosphere and since CO2 dissolved in the water causes it to be slightly acidic
Which of the following statements is true? a. The critical temperature must be reached to change liquid to gas. b. To melt a solid at constant pressure, the temperature must be above the triple point.
