Chemical reactions occur because different types of molecules interact with each other to create new substances. Many of these interactions happen naturally and are not man-made. When one molecule interacts with another one, a chemical reaction occurs due to the breaking of old bonds and the forming

There are several components, including catalysts, heat and pressure, that when added to chemicals and chemical reactions incite or speed up the reaction process. One of the most helpful biological additives in chemical reactions are enzymes.

During a chemical reaction, atoms react with each other to form new products. Atomic bonds in reactants are broken and new ones are formed for creating new products.

Chemical reactions that produce heat are called exothermic reactions. Exothermic reactions involve physical or chemical changes that generate heat in various quantities, which is then dispersed into the surrounding environment. Exothermic reactions come in several forms, and require more energy to o

Three chemical reactions in a kitchen occur when a cook bakes a cake, boils an egg or grills a hamburger. Chemical reactions happen when food spoils, such as when milk goes sour and bananas rot. A match that lights a candle or a stove's burner also uses a chemical reaction.

Chemical reactions that release energy are described by Education.com as exothermic reactions, and their equations follow the form: reactants = products + energy. Examples of exothermic reactions are explosions, such as fireworks, or combustion, such as with engines. The reactants of exothermic reac

Five chemical reactions that can be done at home are an erupting volcano, melting a foam cup with acetone, pouring vinegar on rocks to test for calcium carbonate, destructing black ink and rusting steel wool. These little experiments are simple and use common household products.

All chemical reactions have a conservation of mass. The law of conservation of mass states that atoms cannot be created nor destroyed in a chemical reaction. This discovery, made by Antoine Lavoisier in1789, is the basic foundation for modern chemistry.

Heating sugar results in caramelization and is a chemical reaction. A chemical reaction is the process in which one substance is altered and forms a new substance with differing properties.

The chemical reaction for the burning of sugar by the body is shown through the chemical equation C12H22O11(s) + 12 O2(g) ----- 12 CO2(g) + 11 H2O(l). In this equation, C12H22O11 is the sugar, which burns by reacting with the oxygen to create carbon dioxide and water.
