Experiment 3. Intermolecular forces: solutions

Postlab questions

Question 1.

The only insoluble liquids were hexane and water, meaning the hydrogen bonds in water are higher in

energy than in a solution that has interactions between the two solvents. The difference in polarity

between these two compounds accounts for their immiscibility.

Question 2.

All soluble liquids had dipole-dipole interactions or hydrogen bonds, as well as dispersion forces given the

presence of alkane chains. In acetone, the dipole-dipole forces were broken to form new dipole-dipole

bonds between acetone and water. In hexane, the intramolecular dispersion forces were broken to form

new interactions between the alkyl chains of hexane and butanol.

Question 3.

1-butanol and hexane were slightly soluble given that the first is a polar compound with hydrogen bonds

and the latter is an alkane with only dispersion forces. The energy of intramolecular bonds is higher than

the potential intermolecular bonds and therefore they are insoluble in each other.

Question 5.

Lab AssignmentWelcome to the Lab component of Physics I. This week's lab is called "Sound Waves." You will conduct experiments to see how sound waves behave.First, download and read the two documents below:Click here for the user's guide for "Sound Waves"Click here for the instructions for the "Standing Waves in an Air Column" labNow, log into your account. https://virtuallabs.ket.org/physics/Watch the video overview (remember, there is no sound). Watch the arrow as it shows you where to click to perform the lab. You will also find the instructions in the PDF documents to be extremely helpful as you work the lab.Then, get into the Virtual Physics Lab and run several experiments, using a wide variety of data points. You need to generate a Lab Report to submit for this assignment. Here are the criteria for the Lab Report:Introduction/Thesis (Explain the principles you are studying, and what results you expect to see in this experiment)Background (Explain the concepts that form the foundation for this lab)Methodology (Explain the apparatus used, and how you manipulated the apparatus)Data (Include screen shots from the Grapher, or spreadsheets that contain data, or any charts or graphs you created)Analysis (Look over the data and analyze the results - were results consistent with original expectations, or did you see something different?)Conclusions (Provide your interpretation of what happened with this set of data; provide explanations of why the results turned out the way they did; indicate what sources of error may have impacted the experiment, and anticipate what should happen in future research)Virtual LabUser: ricansoldier82Pass: howitzer1

foundations w5 d5

The dangers inherent in police work are brought to the public’s mind when police are killed in the line of duty. This is especially true when it is apparent that the officers were deliberately ambushed. Clearly, the relationship between police and community differs widely from place to place. Discuss how perceptions of police can differ across different communities or cultures. Critics of police have questioned the “militarization” of local police in America. Explain what is meant by this term and analyze whether it is an accurate characterization. Earlier in the course, we examined “positive” theories, which suggest that criminal behavior is often influenced by factors outside the offender’s control. Can positive theories apply also to police officers who use excessive force or otherwise abuse their power? Police agencies across the country are increasingly turning to the use of “body cams.” These are devices worn on the uniform of a patrol officer in order to record audio and video during encounters with residents. Proponents believe body cams will deter and detect instances of police misconduct. What are the drawbacks of body cameras? What position do police unions take on this issue?
