Synthesis, decomposition, substitution and double displacement are four types of chemical reactions. A synthesis reaction is when two or more reactants combine to form one product.


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.


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


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 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


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.


Five indicators of a chemical change are color change, temperature change, precipitate formation, gas bubble formation and smell or taste change. Since some chemical products are poisonous, detecting a chemical reaction via smell or taste change is not recommended.


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.


In chemical reactions, chemical bonds are broken and reformed, and preexisting chemical bonds that contained a greater amount of energy than the newly created bonds will release their excess bond energy. When energy is released from a chemical reaction through the reformation of a chemical bond requ


Burning a match is a chemical reaction because the reactant, primarily wood, is chemically altered into a different substance, ash. A chemical reaction or change involves one or more reactants having bonds broken or altered to form new substances. In the case of burning a match, wood and oxygen are
