Chemical reactions are happening around you all the time. A match burns. A car rusts. Food spoils. Leaves decay. These are just a few chemical reactions. Probably the most important chemical reactions take place in your body. They are happening this very moment. is a chemical process. So is In every one of your of cells, chemical Digestion respiration. trillions reactions are taking place all the time. Life depends upon chemical reactions. There are several kinds of chemical reactions. One kind is a reaction. synthesis putting “Synthesis” means A synthesis reaction substances, usually elements (but sometimes smaller compounds), to together. combines form a new, larger compound. When the compound forms, we say it has been synthesized. Below is a “model” of a synthesis reaction. A + B AB → Element + Element Compound → 1. RUSTING When iron rusts, it with oxygen. combines 4Fe + 3O2 2Fe2O3 → iron + oxygen iron oxide (rust) → Element + Element Compound 2. THE BURNING OF CARBON Charcoal is made of the element carbon, C. When carbon burns, it with oxygen. This produces the gas carbon dioxide, CO2. combines C + O2 CO2 → carbon + oxygen carbon dioxide → Element + Element Compound A synthesis reaction is like any other kind of chemical reaction. No matter is created or destroyed. The atoms just change their arrangement. Equation I: CO2 + C 2CO2 Equation II: CO2 + H2O H2CO3 → → 120. How is Equation I different from the other synthesis equations seen in this packet? ________________
