Endothermic and exothermic reactions are chemical reactions that involve the absorption or release of energy. An endothermic reaction is a reaction where energy is needed in order to break the bonds of the reactants, while an exothermic reaction is a reaction where energy is released when the bonds of the reactants are broken.
Types of Reactions Covered in the Worksheet
This worksheet covers several types of endothermic and exothermic reactions, including single-displacement reactions, combustion reactions, synthesis reactions, and decomposition reactions. In single-displacement reactions, one reactant is displaced by another, such as when zinc displaces copper in a copper sulfate solution. Combustion reactions are exothermic reactions in which a fuel is combined with oxygen to form carbon dioxide and water. Synthesis reactions involve the combination of two or more reactants to form a single product, and decomposition reactions involve the breaking down of a single reactant into two or more products.
Format of the Worksheet
The worksheet consists of several questions, each of which is followed by four possible answers. Students are asked to identify the endothermic or exothermic reaction that is described in the question, and then select the correct answer from the four choices. The worksheet also includes a brief explanation of each type of reaction, as well as a few examples to illustrate the concepts.
