This module introduces balancing chemical reactions with stoichiometric coefficients. Includes a link to an interactive website for practicing balancing reactions, a video showing specific practice problems, and a video with animations as visual aids demonstrating why we balance chemical reactions.
This Module teaches how to convert mass % to empirical formula, how to identify empirical and molecular formulas, and how to calculate molar mass of a compound.
This module covers four areas of enthalpy:1- introduction to enthalpy and reaction-energy diagrams; define exothermic and endothermic2- Thermochemical expressions and manipulating enthalpy3- Hess's Law4- Enthalpies of formation to find enthalpy of reaction
This module includes an interactive acid-base titration that allows students to select an acid (general "strong" or several weak), initial concentration of the acid and base, and initial volume of the acid. Then, students click on the virtual stopcock to add base.The curve is generated while the correct equation is highlighted for each part of the titration.
This module is a brief introduction to the definitions of mixture, compound, and element and includes a Ted Ed video on What's in a Mixture: the science of macaroni salad.
This module is a brief introduction to making a distinction between kinetic and potential energy. The laws of potential energy inform many of our definitions later in chemistry and are especially useful when related specifically to charges.
This multi-part module introduces covalent bonding and Lewis structures as a model of covalent bonding.Starting with valence electrons, a method of connecting unpaired electrons and/or redistributing valence electrons to satisfy the octet rule is introduced.Numerous examples are presented including CO, ozone, and polyatomic ions
This module is an introduction to the relationship between stoichiometric coefficients, limiting and excess reactant, and theoretical yield. Includes a worked example asking for theoretical yield given two starting masses, to identify the limiting reactant, and calculate the percent yield from a given hypothetical "actual" yield.
This module is an introduction to using VSEPR to predict molecular shape based on Lewis structures. It is limited to steric numbers of 6 or less.
This module teaches the basic rules of naming binary compounds for general chemistry. Hydrocarbons and acids are not included.
This module includes a mini-lecture (5 minutes) that defines specific heat capacity and includes an examples (no unit conversions).
This is a fun way to engage students on paradoxes or misconceptions about physical properties. This module specifically targets common misconceptions about temperature, heat, and thermal conductivity.
This module has two parts: an introduction (rules) to predicting products based on the 5 reaction types; and a video with three specific examples.This module does not cover net ionic equations, balancing, or phase designations.
This module is an introduction to Accuracy, Precision, and Sig figs. It includes how to count the number of significant digits and defining accuracy versus precision.
This module includes solubility rules, how to use the solubility rules, calculating moles of ions from grams of compound, and how to write Net Ionic Equations.
This module is a brief introduction to why Atomic Theory is accepted by the scientific community, and by extension, the public. Highlighting the basis of evidence for acceptance of all scientific discoveries ties into the Scientific Method module.Videos include two Ted Ed videos and a short lecture description of the 3 Laws that support Atomic Theory.
This module gives an overview of the main types of chemical reactions in first-semester general chemistry:1- Combination2- Decomposition3- Single Displacement4- Double Displacement5- Combustion
