State how each of the following effect the entropy of a system (increases, decreases, no change). Increasing temperature [IT] Decreasing molar mass [DMM] Decreasing molar complexity[DMC] Dissolving a silver chloride in water[DSC] Adding a metal catalyst [NC]

You must show your work for this problem.  Place the setup and the calculation on paper (give the number of the question and show all your work) and enter the final answer here on Canvas.  When you are done the exam, take a picture of your work and upload it into the exam 3 work upload area. The answer you have here for the question(s) must match the work you provide in the upload area. (Keep in mind that in order to get full credit your must upload your work). Determine the temperature at which the decompostion of dinitrogen pentaoxide become spontaneous? (enter your answer as the minimal temperature needed to make the reaction spontaneous, you should enter the answer with 1 decimal place and no units, the understood unit is oC)                           ΔHrxn = + [h] kJ;     ΔS = +[s] J/K

(a). pH before the start of the titration (b). pH after the addition of 3.50 mL of NaOH (c). pH at the half titration point (d) pH at the equivalence point (e) pH at 0.40mL after the equivalence

Discuss the Cadmium problem in Alaska (see handout).  Use both the Ksp and Kf concepts with equations/calculations to support your discussion. (FYI: in case you don’t recall from CHM2045 ionic salt of nitrate are very soluble)

How has your understanding of trig functions changed as a result of this activity? Be specific.

You will need to use an AI assistant. Copy and paste these prompts exactly as given, with the name of your individually assigned city (see list of assigned cities in the directions above). Ask AI to “generate a data set for hours of daylight for {insert your assigned city} for the 1st and 15th of each month in 2025” Ask AI to “create a scatter plot of this data with labels for each ordered pair” Ask AI to “model this data with a sinusoidal equation and superimpose the model on the scatterplot” Copy and paste the whole AI chat into the textbox. REMINDER: You will not be able to come back to this question later, so you must be sure to complete all the steps above in the tab with your preferred AI assistant. Then copy and paste the whole chat into the textbox before you click next.

Discuss how well the model fits the data graphically. Comment on accuracy (i.e., Where does it fit well? Where does it deviate?).

Interrogatories are oral questions for which written answers are prepared and signed under oath.

You are caring for a client (G3P2) that is 36-weeks-gestation who entered the labor and delivery area with spontaneous rupture of membranes. The nurse looks at the patient’s fetal heart rate tracing and notices a pattern of variable decelerations. The provider is notified and orders an amnioinfusion to be started. What is the potential benefit of an amnioinfusion?
