CHEM 29N: Chemistry in the Kitchen

This course examines the chemistry relevant to food and drink preparation, both in homes and in restaurants, which makes what we consume more pleasurable. Good cooking is more often considered an art rather than a science, but a small bit of understanding goes a long way to make the preparation and consumption of food and drink more enjoyable. The intention is to have demonstrations and tastings as a part of every class meeting. We will examine some rather familiar items in this course: eggs, dairy products, meats, breads, vegetables, pastries, and carbonated beverages. We shall playfully explore the chemistry that turns food into meals. A high-school chemistry background is assumed; bring to class a good appetite and a healthy curiosity.

CHEM 31A: Chemical Principles I

31A is the first course in a two-quarter sequence designed to provide a robust foundation in key chemical principles for students with a basic background in high school chemistry, who have already placed into Math 19 or higher. The course engages students in group problem-solving activities throughout the class periods to deepen their ability to analyze and solve chemical problems. Students will also participate in a weekly laboratory activity that will immediately apply and expand upon classroom content. Labs and write-ups provide practice developing conceptual models that can explain qualitatively and quantitatively a wide range of chemical phenomena. The course will introduce a common language of dimensional analysis, stoichiometry, and molecular naming that enables students to write chemical reactions, quantify reaction yield, and calculate empirical and molecular formulas. Stoichiometry will be immediately reinforced through a specific study of gases and their properties. Student more »

Stoichiometry will be immediately reinforced through a specific study of gases and their properties. Students will also build a fundamental understanding of atomic and molecular structure by identifying interactions among nuclei, electrons, atoms and molecules. Through both lab and in-class exploration, students will learn to explain how these interactions determine the structures and properties of pure substances and mixtures using various bonding models including Lewis Dot, VSEPR, and Molecular Orbital Theory. Students will identify and quantitate the types and amounts of energy changes that accompany these interactions, phase changes, and chemical reactions, as they prepare to explore chemical dynamics in greater depth in 31B. Special emphasis will be placed on applying content and skills to real world applications such as estimating the carbon efficiency of fossil fuels, understanding hydrogen bonding and other interactions critical to DNA, and calculating the pressure exerted on a deep-sea diver. Prerequisites: Math 18 and Chem11 or placement into Chem31A with Autumn General Chemistry Placement test. All students who are interested in taking general chemistry at Stanford must take the General Chemistry Placement Test before the Autumn quarter begins, regardless of chemistry background, to enroll.

CHEM 31B: Chemical Principles II

Chem 31B is the second course in this two-quarter sequence, therefore only students who have completed Chem 31A may enroll in 31B. As with 31A, students will continue to engage in group problem-solving activities throughout class and participate in weekly laboratory activities. Labs and write-ups will allow students to more deeply explore and observe the different facets of chemical reactivity, including rates (kinetics), energetics (thermodynamics), and reversibility (equilibrium) of reactions. Through experimentation and discussion, students will determine what forces influence the rate of chemical reactions and learn how this can be applied to enzyme reactivity. Students will quantify chemical concentrations during a reaction, and predict the direction in which a reaction will shift in order to achieve equilibrium, including solubility equilibria. They will use these methods to estimate the possible levels of lead and other toxic metals in drinking water. Special emphasis will be p more »

They will use these methods to estimate the possible levels of lead and other toxic metals in drinking water. Special emphasis will be placed on acid/base equilibria , allowing students to explore the role of buffers and antacids in our bodies, as well as ocean acidification and the impact on coral reefs. Students will then bring together concepts from both kinetics and equilibrium, in a deeper discussion of thermodynamics, to understand what ultimately influences the spontaneity of a reaction. Students will build a relationship between free energy, temperature, and equilibrium constants to be able to calculate the free energy of a reaction and understand how processes in our body are coupled to harness excess free energy to do useful work. Finally we will explore how we harness work from redox reactions, building both voltaic cells (i.e. batteries) and electrolytic cells in lab, and using reduction potentials to predict spontaneity and potential of a given reaction. We will look at the applications of redox chemistry in electric and fuel cell vehicles. The course's particular emphasis on understanding the driving forces of a reaction, especially the influence of thermodynamics versus kinetics, will prepare students for further study of predicting organic chemical reactivity and equilibria from structure in Chem 33. Prerequisite: Chem 31A.

CHEM 31S: STEMentors in Chemistry

STEMentors in Chemistry has been designed to provide timely support for students in CHEM 31A with study and problem-solving skills applicable in both chemistry and STEM courses in general. Students will join a small cohort of other CHEM31A students looking to build community with and support other students in STEM. Weekly sections will focus on group activities and individual check-ins facilitated by a peer mentor who has previously taken the CHEM 31A/B sequence. These activities are designed to normalize challenging experiences within a college science course, build key study skills such as how to effectively review lecture notes and practice problems, prepare for and reflect on exams, and develop a consistent problem-solving process that will build student confidence over the quarter. Students should enroll in a weekly mentor section, occurring on Thursdays. You can read more about our individual mentors here: https://chemistrystementors.sites.stanford.edu/people-0.
