Chem120 concepts - Study guides, Class notes & Summaries

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.

In this concept, we will discuss one class of biological polymers called lipids or fats. You might be familiar with this class of biopolymers, which are found in butters and oils. We will discuss saturated and unsaturated fats, and what those terms mean for the molecule's structure as well as its properties at room temperature. 1. Which of the following is a source of lipids?

Reduction and oxidation are intertwined concepts that are important to understanding some of the most important chemical reactions in the human body. In this lesson, we will explore the relationship between these terms and the how to identify what chemicals in a reduction/oxidation reaction (redox reaction) are playing which parts.

PHYSICAL STATES OF MATTER In this section, we will discuss the Ideal Gas Laws. First, we will review the properties of solids, liquids, and gases. Second, we will discuss the kinetic-molecular theory of gases, which explains why they are so unique compared to other states of matter. Finally, we will discuss gas law equations, and practice using them to solve for different parameters. This unit has many strong connections to our daily lives as we are surrounded by examples of the materials we ar...

Introduction Building on the fundamentals of covalent bonding, we will be looking deeper into the structures and behaviors of molecular compounds. We will be exploring how covalent bonding is involved in the structure of these molecules and determines how they interact with the world around them.

Introduction: Just like in preparing your favorite foods, recipes exist for chemicals as well. We can use balanced chemical equations just like a recipe in your favorite cookbook. In chemistry, this process is called stoichiometry.

ATOMIC STRUCTURE In many ways, this lesson is the start of your journey into chemistry. In this foundational lesson, we will learn about the building blocks of matter: atoms. Alchemists, the precursors to chemists, had a saying: “As above, so below”. A modern interpretation of this saying is that the properties of what we can see can help us understand the properties of what we cannot. In this lesson, we will learn how the properties of atoms determine the properties of the world around us.
