For example, we can describe the chemical reactions that occur in the physical world using chemical equations. These equations include symbols with specific meanings. The key features of a chemical equation are pointed out here: Example of a chemical equation with reactants on the left and products on the right.
May 18, 2021 · In this chapter, we will learn the meaning of the symbols used in chemistry to represent elements and compounds, and the information these symbols convey microscopically and macroscopically.
Jun 30, 2019 · We will start off with an introduction to basic chemistry: background on the most basic definitions of chemistry, a bit of history, and highlighting why and how chemistry is important. The basic units in chemistry will be defined: atoms, molecules, subatomic particles.
Jun 23, 2022 · Physical properties are characteristics that describe matter as it exists. Some physical characteristics of matter are shape, color, size, and temperature. An important physical property is the phase (or state) of matter. The three fundamental phases of matter are solid, liquid, and gas (Figure 1.2.1 1.2. 1 ).
In this chemistry tutorial, we explain the difference between polar bonds and non-polar bonds. We then tell you the definition of a polar molecule, and what a non-polar molecule is. Last, but not least, you learn what a dipole moment is.
Apr 8, 2022 · In your Chemistry II class, you need to master several formulas so you can calculate different mathematical problems, ranging from kinetics, different types of equilibrium, thermochemistry, and electrochemistry. This Cheat Sheet can serve as a quick reference to how to solve kinetics, thermodynamics, and different types of equilibrium problems.
Mar 5, 2020 · A lower pH means something is more acidic, also known as a stronger acid. A higher pH means it is more alkaline or a stronger base. Chemistry classes will often use a litmus test to identify acids from bases. A blue litmus paper turns red in acids while a red litmus paper turns blue in basic solutions.
