Question
Chapter 15, Problem 66AP
Interpretation Introduction
Interpretation:
To determine if the process used in cold packs that are dissolving ammonium nitrate in water is an endothermic or an exothermic process.
Concept Introduction:
Endothermic process − A process wherein the energy in the surrounding is absorbed is said to be as an endothermic process. This is generally absorbed in the form of heat. This process, in turn, cools the surrounding environment. In other words, the energy required to break the reactants’ bonds is more than the energy released by the products.
Exothermic process − A process wherein energy is released out is said to be as an exothermic reaction. The energy could be released in the form of heat or light. In other words, the energy required to break the reactants’ bonds is less than the energy released by the new bonds that occur in the products and this excess energy is released as heat. This process heats up the surroundings.

- Heparin is used as an anti-coagulant. A risk of heparin use is thrombocytopenia, or low platelet count. This risk is minimized with the use of low molecular weight heparins (LMWH), therefore it is desirable to separate LMWH from higher molecular weight heparins. The method of choice to do this is molecular exclusion chromatography. Below is a chromatogram from a molecular exclusion chromatographic run. Peaks ranging from A to J are clearly distinguishable. The heparin mixture that was analyzed had anywhere from 6 to 30 repeat units of monomer (where the heparin with 30 repeat units would be roughly five times the size of the heparin with six repeat units). a. Which letter most likely represents the peak with 6 repeat units given these heparin polymers were separated with molecular exclusion chromatography? b.
