Answer:
Explanation:
Hello,
At first, we compute liquid-phase molar fractions:
Now, by means of the fugacity concept, for hexane, for instance, we have:
In this manner, at 25 °C the vapor pressure of hexane and heptane are 0.198946 atm and 0.013912 atm repectively, thus, the total pressure is:
Finally, from the hexane's fugacity equation, we find its mole fraction in the vapour as:
Best regards.
Test the hypothesis in an expirement!
If you don’t mind can u add the picture?? It helps me answer the question better ;)
I believe the answer is a. A passive prosthesis
Prosthesis is used to replace a part of the patient. Some prosthesis powered by external source that allow it to do some degree of movement. Passive prosthesis doesn't have electronic or mechanic part, which makes their function is more to be cosmetic than function.
Answer:
Importance of Phlogiston Theory . Although the theory has since been discarded, it's important because it shows the transition between alchemists believing in the traditional elements of earth, air, fire, and water, and true chemists, who conducted experimentation that led to the identification of true chemical elements and their reactions.
