Hi! Which of the following decreases kinetic energy of solvent molecules? ( I need this handed in quickly!)
A. Decreasing the pressure
B. Not stirring the solution
C. Decreasing the contact area between solvent and solute
When a drop of water sits on a leaf, It looks like it has a skin. What is this “skin” a result of? Explain.
What does adding soap do in terms of dissolving solutes? Explain.
Which solution will contain a higher concentration of iodide ions, 0.25 mol/L calcium iodide or .45 mol/L potassium iodide?
Thank you so much! I hope you have a great day!❤️
Answer:
c
Explanation:
According to the forces of attraction, decreasing the contact area between solvent and solute decreases kinetic energy of solvent molecules.
What are forces of attraction?Forces of attraction is a force by which atoms in a molecule combine. it is basically an attractive force in nature. It can act between an ion and an atom as well.It varies for different states of matter that is solids, liquids and gases.
The forces of attraction are maximum in solids as the molecules present in solid are tightly held while it is minimum in gases as the molecules are far apart . The forces of attraction in liquids is intermediate of solids and gases.
The physical properties such as melting point, boiling point, density are all dependent on forces of attraction which exists in the substances.

Objective(s):
In your own words, what was the purpose of this lab?
Hypothesis:
In this section, please include the if/then statements you developed during your lab activity. These statements reflect your predicted outcomes for the experiment.
If predators are increased, then the cricket frog population will (increase/decrease/stay the same) over the span of five years.
If pollution is increased, then the cricket frog population will (increase/decrease/stay the same) over the span of five years.
If the amount of food available is increased, then the cricket frog population will (increase/decrease/stay the same) over the span of five years.
Procedure:
The procedures are listed in your virtual lab. You do not need to repeat them here. Please be sure to identify the test variable (independent variable), outcome variable (dependent variable), and control group for this experiment.
Reminder: The test variable is the item that is changing in this investigation. The outcome variable is the item that you are measuring in this investigation. The control group is the group in the experiment where the factors being tested are not applied. It allows scientists to set a baseline to compare the experimental groups that do have factors applied to them.
Test variable (independent variable):
Outcome variable (dependent variable):
Control group:
Data:
Record your data from each trial in the data chart below:
Type of Factor Beginning Frog Count Simulation 1 (Low) Simulation 2 (High)
Predators (alligators)
Pollution
Food (mosquitoes)
Graphs
Use the graphs you printed from the data chart in the virtual lab and analyze the data. Make a note of any trends that you discover.
Predators (alligators):
Pollution:
Food (mosquitoes):
Conclusion:
Your conclusion will include a summary and an interpretation of the lab results. Please write in complete sentences.
