A typical human liver weighs about 1.4 kilograms. if it is to be used in a transplant procedure, a harvested liver is usually chilled for transport in a new supercooling technique, the liver is perfused (flooded) with a sugar solution to act as antifreeze and then cooled from body temperature (37 C) to -4 C. You can assume that after perfusion almost all the liver's weight is due to the sugar solution. The sugar solution has the following properties: cp 3.11 kj/kg*K, p = 1150 kg/m^3, A Hfusion = 294 kJ/kg. A. What is the change in entropy of the perfused liver during cooling? List all assumptions made. B. If the body temperature liver was not perfused with the sugar solution and was cooled to 4 C, how would you expect the change in entropy of the liver to be different. Explain your answer

When selling on the street, dealers may not know the purity of the ketamine they have, and thus users do not know exactly how much ketamine they are receiving. It is unlikely that the ketamine is pure, or even that different batches of ketamine have the same purity. Assume the drug the user typically buys is only 25%25% ketamine, and therefore, the user actually dissolved 0.250 g0.250 g ketamine in 1/41/4 cup of water to make the solution instead of 1 g1 g in the previous question. 1 cup=236.5 mL1 cup=236.5 mL What volume of this ketamine solution would the 71.0 kg71.0 kg user have to inject to experience a high at 0.500 mg/kg

For hospital patients suffering from dehydration, it may be necessary to provide them with intravenous fluids. A common IV bag used for this purpose contains 4.00% (wv) glucose (MW = 180.16 g/mole) and 0.450% (w/v) of sodium chloride (MW = 58.44 g/mole). If you were attempting to prepare a standard 1.00 L bag of this solution starting from a stock solution containing 30.0% (w/v) glucose and 3.38% (w/v) sodium chloride, how many mL of the stock solution would you need? Hint: Only one calculation is needed.

Cold packs (like the kind used by athletes to treat sprains and other minor injuries) rely on the fact that the enthalpy of dissolution of ammonium nitrate is positive. Is this an exothermic or endothermic reaction? Exothermic Endothermic Neither because this is a closed system and therefore no heat is lost.
When answering this problem, report the answer with the appropriate number of significant figures. When entering units, use proper abbreviated units with proper capitalization. A student followed the procedure in this experiment, using 50.00 mL of 2.00 molar HCl and 51.00 mL of 2.00 molar NaOH both solutions having an initial temperature of 22.7 oC. After mixing, a maximum temperature of 32.2 oC is measured. The final mass of the mixture was found to be 107.87 grams. For this problem, assume the specific heat of the solution is 4.18 J/g oC. Report all answers with the proper number of significant figures. What is the heat transferred by this reaction, in Joules?
