Amoxicillin is an antibiotic packaged as a powder. When it is used to treat babies and small animals, the pharmacist or veterinarian must suspend it in water, so that it can be administered orally with a medicine dropper. The label says to dispose of unused suspension after 14 days. It also points out that refrigeration is required. In the context of this chapter, what is implied in the latter two statements?
How does the process described in the previous item relate to the system shown in Figure 16.4?

A chemical engineer must calculate the maximum safe operating temperature of a high-pressure gas reaction vessel. the vessel is stainless steal cylinder that measures 40.0 cm wide and 48.0 cm high. the maximum safe pressure inside the vessel has been measured to be 3.60 MPa. For a certain reaction the vessel may contain up to 1.13kg of carbon monoxide gas. Calculate the maximum safe operating temperature the engineer should recommend for this reaction. write your answer in degrees celsius. Round your answer to 3 significant digits.
5. Two aqueous NaCl solutions of equal volume and concentration were kept in flasks and held at different temperatures. The two solutions were combined in a larger flask. Based on this information, which of the following predictions is correct?a. The average kinetic energy of the particles in the cooler solution will decrease as they collide with the particles from the warmer solution.b. The average kinetic energy of the particles in the cooler solution will increase as they collide with the particles from the warmer solution.c. The particles from the cooler solution and the particles from the warmer solution will reach thermal equilibrium through collisions, at which time theaverage kinetic energy of the particles in the mixture will be lower than theaverage kinetic energy that the particles had in the cooler solution.d.

A student dissolves 13.7 g of potassium hydroxide KOH in 200. g of water in a well-insulated open cup. He then observes the temperature of the water rise from 22.0°C to 34.0°C over the course of 7.3 minutes. KOHs + K+aq -> OH−aq You can make any reasonable assumptions about the physical properties of the solution. Be sure answers you calculate using measured data are rounded to the correct number of significant digits. Is this reaction exothermic, endothermic, or neither? If you said the reaction was exothermic or endothermic, calculate the amount of heat that was released or absorbed by the reaction in this case. Calculate the reaction enthalpy ΔHrxn per mole of KOH .
