Cats Have Nine Lives, But Only One Liver: The Effects of Acetaminophen
Rating
0.0 stars

In this case, a college student gives her cat Tylenol not knowing its potential harmful effects. The cat survives, but the incident motivates her to research the reaction mechanism underlying the liver toxicity of acetaminophen. The case outlines possible reaction schemes that would explain why acetaminophen-containing products can be toxic to the liver. Students are required to write a detailed mechanism for each. The case also presents evidence from the literature that supports one of the reaction schemes and eliminates the others. Students must identify the correct reaction scheme and mechanism based on this evidence. The case can be used in undergraduate organic chemistry, biochemistry, medicinal chemistry, and pharmacology courses.

Chemical Engineering Thermodynamics, Fall 2003
Rating
0.0 stars

This course aims to connect the principles, concepts, and laws/postulates of classical and statistical thermodynamics to applications that require quantitative knowledge of thermodynamic properties from a macroscopic to a molecular level. It covers their basic postulates of classical thermodynamics and their application to transient open and closed systems, criteria of stability and equilibria, as well as constitutive property models of pure materials and mixtures emphasizing molecular-level effects using the formalism of statistical mechanics. Phase and chemical equilibria of multicomponent systems are covered. Applications are emphasized through extensive problem work relating to practical cases.

Chemical Reactions:  Investigating Exothermic and Endothermic Reactions
Rating
0.0 stars

This activity is an inquiry-based investigation where students discover the indicators of chemical reactions (endothermic and exothermic) by collecting data and using that data to develop a testable question for further experimentation.

Chemical Reactions  and Pancakes
Rating
0.0 stars

Students will compare ingredients in two different pancake recipes, then taste the difference. We will talk about the chemical reaction that happened when the recipes are mixed and why there are bubbles in the pancakes.

Chemical Wonders
Rating
0.0 stars

Students are introduced to chemical engineering and learn about its many different applications. They are provided with a basic introduction to matter and its different properties and states. An associated hands-on activity gives students a chance to test their knowledge of the states of matter and how to make observations using their five senses: touch, smell, sound, sight and taste.

Chemistry: Atoms First
Rating
0.0 stars

Chemistry: Atoms First is a peer-reviewed, openly licensed introductory textbook produced through a collaborative publishing partnership between OpenStax and the University of Connecticut and UConn Undergraduate Student Government Association.

This title is an adaptation of the OpenStax Chemistry text and covers scope and sequence requirements of the two-semester general chemistry course. Reordered to fit an atoms first approach, this title introduces atomic and molecular structure much earlier than the traditional approach, delaying the introduction of more abstract material so students have time to acclimate to the study of chemistry. Chemistry: Atoms First also provides a basis for understanding the application of quantitative principles to the chemistry that underlies the entire course.
