Paul Andersen describes the macromolecules that make up living organisms. He starts with a brief description of organic chemistry and the importance of functional groups. He also covers both dehydration and hydrolysis in polymerization. He finally covers the four major macromolecules: nucleic acids, proteins, lipids and carbohydrates.
Paul Andersen attempts to explain Gibbs Free Energy. He begins by using three spontaneous reactions to explain how a change in enthalpy, entropy and temperature can affect the free energy of a system. He then applies this concept to cellular respiration and photosynthesis.
Mr. Andersen explains how carbon-14 dating can be used to date ancient material. The half-life of radioactive carbon into nitrogen is also discusse
Mr. Andersen explains why radiation occurs and describes the major types of radiation. He also shows how alpha, beta, and gamma radiation affect the nucleus of a radioactive atom. Nuclear equations are also discussed.
Mr. Andersen contrasts nuclear reactions to chemical reactions. He explains the four main forces of nature; including gravity, electromagnetism, strong, and weak nuclear forces. He also explains how fusion differs from fission.
Mr. Andersen discusses the disassociation of water and the properties of acids and bases. He also discriminates between strong and weak acids and bases.
Mr. Andersen explain solubility. He also describes the solubility curves for solids and gases in solution. A brief description of dissolved oxygen is also included.
Mr. Andersen describes solutions. He also shows how to differentiate a solution from a colloid and a suspension. He explains the concept of molarity and solves a few molarity problems.
Mr. Andersen explains why water is a polar molecule. He also explains why this gives water properties like cohesion,high specific heat, less dense ice, and the ability to act as a solvent. All of these properties are due to hydrogen bonding.
Mr. Andersen explains the concept of a limiting reactant (or a limiting reagent) in a chemical reaction. He also shows you how to calculate the limiting reactant and the percent yield in a chemical reaction.
Mr. Andersen explains the basics of balancing chemical equations. A visual guide shows you how to change coefficients to balance the atoms in reactants and products.
Mr. Andersen shows you how to convert moles to grams and moles to molecules.
Mr. Andersen explains the difference between physical and chemical changes. A brief discussion of chemical reactions and equations is also included.
Mr. Andersen shows you how write the chemical formula for chemical names. More specific examples of naming covalent and ionic compounds.
Mr. Andersen shows you how to name covalent and ionic compounds. Introduction to the rules of naming covalent and ionic compounds.
Mr. Andersen shows you how to determine if a bond is nonpolar covalent, polar covalent, or ionic.
Mr. Andersen describes the major groups on the periodic table.
Mr. Andersen shows you how to draw Lewis Dot Diagrams for atoms and simple molecules.
Mr. Andersen describes atomic structure and tours the periodic table.
Mr. Andersen details the history of modern atomic theory.
