- Chapter 1.4: A Brief History of Chemistry
- This page outlines a general chemistry course focusing on atomic theory, molecular structure, stoichiometry, thermochemistry, states of matter, kinetics, equilibria, and materials. It highlights the development of atomic theory from ancient Greek thought to modern science, discussing key figures like Democritus, Robert Boyle, Joseph Priestley, and Antoine Lavoisier. It explains fundamental chemical laws, Dalton's atomic theory, Avogadro's hypothesis, and the law of multiple proportions.
- Chapter 1.7: The Mole and Molar Mass
- This page is a detailed exploration of fundamental chemistry concepts, focusing on atomic theory, molecular mass, the mole, and molar mass. It outlines methods to calculate molecular mass, using examples like ethanol and trichlorofluoromethane. The mole, a core chemical unit, is discussed in depth, including its definition, significance, and Avogadro's number.
