1. The enthalpy change associated with forming a solution is represented by the following equation AHsolution = AHsolvent + AHsolute + AHmixture When 10 g of solid NH,NO3 is added to 100 mL of water (both initially at room temperature) the NH,NO3 dissolves and the temperature of the solution decreases. Given those facts which of the following statements are true? (More than one statement could be true) a. AHmixture is a positive number (endothermic) b. AHsolution is a positive number (endothermic) The absolute value |AHsovent + AHsolute| is larger than the absolute value |AHmixture C. d. The temperature decreases because the entropy of the system decreases when the NHẠNO3 dissolves.

The Kinetic Molecular model details other aspects of gas particle motion and collisions besides speed. Open the Run Experiment tool under the Experiment tab in the Simulation, and then select the Submicroscopic tab. You can track the motion of an individual gas particle by clicking the Track button in the lower right corner, and you can track a different gas particle by first clicking Pause, then clicking on a gas particle, and finally clicking Resume. Change several of the macroscopic conditions (temperature, pressure, and volume) of the ideal gas and observe how the movement of a tracked gas particle is affected by those changes and collisions. For each condition, make your observations over a consistent amount of time (e.g. 10 s). Then, complete the following statements that describe the atomic behavior of a gas particle. Match the words in the left column to the appropriate blanks in the sentences on the right. Make certain each sentence is complete before submitting your answer. ▸…
