CHEM 120 Week 8 Exam 3 (Units 5, 6, and 7)

In this section, we explore the rules of energy that we observe in the universe. We see many examples of these laws in action on a day-to- day basis. You will learn how to compare and contrast exothermic and endothermic reactions as well as the first and second laws of thermodynamics.

Option 1: While we often think of radiation as dangerous, radioactive isotopes are widely used in the field of healthcare as well as in many other fields. For your initial post, choose a radioactive isotope used in healthcare or another field and report on how your isotope is used. Be sure to answer both of the following questions as part of your initial post: a. What type(s) of radioactive decay does your isotope undergo? b. How is your isotope used? Use at least one outside source and ci...

Learning objectives • Explain the molecular structure of sugars and polysaccharides • Explain digestion and appreciate the complexity of the human body • Experiment with different foods and measure their impact on the blood sugar level Introduction Most people are familiar with carbohydrates, especially when it comes to what we eat. For example, to lose weight, some individuals adhere to “low-carb” diets. Athletes, in contrast, often “carbohydrate-load” before important compet...
