As they perform the experiment, the Mythbusters illustrate two types of chemical reactions. First, dropping an alkali metal in water results in a single-replacement reaction, releasing hydrogen gas. The hydrogen gas then reacts with oxygen in a synthesis reaction, forming water and releasing a lot of energy in the form of heat and light. Chemical reactions involve the movement of electrons, leading to the formation and breaking of chemical bonds. Neither matter nor energy is created or destroyed in a chemical reaction---only changed. Chemical reactions are described by chemical equations. Example: The reaction between hydrogen and oxygen to form water is represented by the following equation. If, or when, hydrogen reacts with oxygen, two moles of hydrogen and one mole of oxygen are consumed for every two moles of water...
