Chemical Reactions A chemical reaction is a “chemical change that occur when chemical bonds between atoms are formed or broken.” The substance that goes into a chemical reaction is the reactant, and the substances produced produced at the end of the reaction are known as products. Chemical reactions are all around us constantly occurring, anything from a candle burning to the rusting on a fence are examples of a chemical reaction. Chemical reactions can be noticed by Chemical Change some example of chemical change are change in temperature, change in color, bubbles, precipitate, light, and odor. Chemical reactions such as combustion or fire, fermentation and the reduction of ores to create…show more content…
Compounds are formed by combination of atoms in simple ratios to give compound atoms.” The theory was the basis of modern chemistry Dalton’s theory provided a basis for understanding the results of earlier experimentalists, including the The Law for Conservation of Matter and the Law of Constant Composition, which stated all samples of a substance have identical elemental compositions. These theory’s and experiments defined the concept of chemical reactions. Thousands of known chemical reactions occur in living things, in industrial processes and in laboratories. To more easily predict the outcome of chemical reactions a basic system of classification was put in place for chemical reactions. The system categorized the reactions into five different groups Synthesis, Decomposition, Single-Replacement Reaction, Double-Replacement, and Combustion reactions. When scientists are creating new compounds from other substances, chemists say they are synthesizing a new material. A synthesis reaction is a reaction where two or more elements or compounds combine to from one compound. This reaction type fallows this general form A + B = AB Where A and B can be either compounds or elements. For example 2Na + Cl = 2NaCl These reactions are
