A video showing that a combustion reaction is an exothermic reaction that releases energy in the form of fire. Video explains and demonstrates the reaction that takes place between hydrogen gas and oxygen gas. [1:55]

This lesson will introduce the energy diagram of a chemical reaction, and label the parts of the diagram.

A video lecture that builds on previous knowledge of enthalpy to find out how much heat energy is either gained or lost in a reaction. By being able to predict how much heat it takes to produce certain products, it is explained to...

Understand the intuition to why Gibb's free energy equation can predict whether a reaction is spontaneous in this video lecture. The lecture goes through scenarios to show how a reaction may happen spontaneously based on enthalpy,...

This lesson will define exothermic and endothermic, and explain the relationship of these terms to transfer of heat during a chemical reaction.
