INTRODUCTION OF CHEMICAL REACTION A chemical reaction is a process in which one set of chemical substances (reactants) is converted into another (products). It involves making and breaking chemical bonds and the rearrangement of atoms. Chemical reactions are represented by balanced chemical equations, with chemical formulas symbolizing reactants and products. A chemical equation is a way to describe what goes on in a chemical reaction, the actual change in a material. Chemical equations are written with the symbols of materials to include elements, ionic or covalent compounds, aqueous solutions, ions, or particles. There is an arrow pointing to the right that indicates the action of the reaction. The materials to the left of the arrow are the reactants, or materials that are going to react. The materials to the right of the arrow are the products, or materials that have been produced by the reaction. There are five main types of chemical reactions: synthesis, decomposition, combustion, single displacement, and double displacement. In this lab, we briefly described each type of reactions and performed small experiments to determine how each reactions work and how they result in. SYNTHETIC REACTION A synthesis reaction is a reaction when two or more substances react to create a single, more complex substance. The components involved in the reaction may be elements, compounds or both combined. The general form of a synthetic reaction looks like this: A + B  AB. Here are 5 examples of synthetic reactions: 1) 2H2 + O2 2H2O (The burning of hydrogen to form water) 2) 2C + O2 C O2 (The burning of carbon to form carbon dioxide) 3) 2CO + O2  2CO2 (The burning of carbon monoxide to form carbon dioxide) 4) CaO + H2O  Ca(OH)2 (The reaction of calcium oxide
