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 limited background in chemistry. 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 weekly labs that will apply and expand upon class content. Due to social distancing guidelines, labs will be held over live Zoom. Students can opt-in to receive an at home lab kit that will allow them to conduct low-risk portions of the labs from their location. TAs will demonstrate and guide students through hands-on portions, as well as supplement with further in-depth video labs, virtual simulations, and problem solving practice. n31A will provide practice developing conceptual models that can explain qualitatively and quantitatively a wide range of chemical phenomena and will be immediately applied to real world challenges. Students practice dimensional analysis, stoichiometry, and molecular naming that enables them to write chemical reactions, quantify reaction yield, and calculate empirical and molecular formulas. Using these skills, students estimate carbon efficiency of fossil fuels and identify unknowns in forensic analysis. Stoichiometry is reinforced through study of gases and their properties, through which students calculate the pressure exerted on a deep-sea diver. Students examine atomic and molecular structure by quantifying interactions among nuclei, electrons, atoms and molecules and explain trends in reactivity, such as why potassium metal catches fire in water. They explore how these interactions determine the structures and properties of pure substances, mixtures, proteins, and even DNA using three conceptual models for bonding: Lewis Dot, VSEPR, and Molecular Orbital Theory. They investigate the types and amounts of energy changes that accompany these interactions, phase changes, and chemical reactions, such as measuring the caloric content of food and dissecting an instant hand warmer. By the end of the course, students will be prepared to explore chemical reactivity in greater depth in 31B. nAll students who are interested in taking general chemistry at Stanford must take the Autumn 2020 General Chemistry Placement Test before Autumn quarter begins, regardless of chemistry background. Students with no AP/IB background are given enrollment priority in the 31A/B sequence.

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 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 31M: Chemical Principles: From Molecules to Solids (MATSCI 31)
A one-quarter course for students who have taken chemistry previously. This course will introduce the basic chemical principles that dictate how and why reactions occur and the structure and properties of important molecules and extended solids that make up our world. As the Central Science, a knowledge of chemistry provides a deep understanding of concepts in fields ranging from materials, environmental science, and engineering to pharmacology and metabolism. Discussions of molecular structure will describe bonding models including Lewis structures, resonance, crystal-field theory, and molecular-orbital theory. We will reveal the chemistry of materials of different dimensionality, with emphasis on symmetry, bonding, and electronic structure of molecules and solids. We will also discuss the kinetics and thermodynamics that govern reactivity and dictate solubility and acid-base equilibria. A two-hour weekly laboratory section accompanies the course to introduce laboratory techniques and reiterate lecture concepts through hands-on activities. Specific discussions will include the structure, properties, and applications of molecules used in medicine, perovskites used in solar cells, and the dramatically different properties of materials with the same composition (for example: diamond, graphite, graphene). There will be three lectures, one two-hour laboratory session, and an optional 80-minute problem solving session each week. The course will assume familiarity with stoichiometry, unit conversions, and gas laws. All students who are interested in taking general chemistry at Stanford must take the Autumn 2020 General Chemistry Placement Test before Autumn quarter begins, regardless of chemistry background. Generally students earning an AP chemistry score of 4 or higher place into 31M. Students earning an AP score of 5 are also welcome to take the Autumn 2020 Chemistry 33 Placement Test to see if Chem33 is a more appropriate placement. Same as:

CHEM 33: Structure and Reactivity of Organic Molecules
An introduction to organic chemistry, the molecular foundation to understanding of life, medicine, imaging, energy, and material science. Students will learn structural and bonding models of organic molecules that provide insights into chemical, physical, and reactivity properties, in addition to their biological activities, collectively contributing to the molecularization and thus advancement of many science disciplines. Combining these models with kinetic and thermodynamic analyses allows molecular conversions to be rationalized. Translation of this knowledge to more complex systems enables the synthesis of novel molecules or materials that can positively impact our science, society and environment. A two-hour weekly lab section accompanies the course to introduce the techniques of separation and identification of organic compounds. Prerequisite:
