![]() The starting materials are always made from pure elements like hydrogen (H) and zinc (Zn), which are added to an aqueous compound such as saltwater and acid solutions. The substitution reaction occurs by displacing one element to another element to form a new compound. The chemical equation of a chemical decomposition may look like this:Ģ H 2O (g) ? 2 H 2 (g) + O Single Displacement or Substitution Reaction The extraction of various metals, the digestion of food, and the electrolysis of water (H 2O) into oxygen (O 2) are good examples of chemical decomposition. In reverse to the synthesis reaction, chemical decomposition breaks compounds into smaller chemical species as its product, following the formula of AB ? A + B. The chemical equation for a synthesis reaction may look like this:Ģ H 2 (g) + O 2 (g) ? 2 H 2O (g) Chemical Decomposition or Analysis Reaction Some good examples of synthesis reactions are the production of water (H 2O), carbon dioxide (CO 2), and ammonia (NH 3). One way to recognize this reaction is that this has more reactants than its products. There are various types of chemical reactions and some of them are:ĭuring a synthesis reaction, two or more elements mix to produce a new product.This type of reaction is one of the most common types of reaction that follows a simple formula of A + B ? AB and is the reverse of the decomposition reaction. Some chemical reactions may either a forward or reverse reaction to obtain the desired product. This may include atoms, ions, compounds, along with molecules of a single element to perform the reaction. The example above shows that 2 H 2 + O 2 are the reactants, while 2 H 2 O is the product of the reaction.Ĭhemical reaction, which was developed by Antoine Lavoisier, takes place when two or more molecules interact with one another and produce a new product through chemical change. In contrast, the subscripts (the small “2” located after “H” and “O”) represents the number of atoms present in a chemical species. The coefficient located next to the symbols (the “2” before “H” from 2 H 2 ) indicates the stoichiometric numbers. Their symbols represent the elements in the chemical equation (which are the H = Hydrogen and O = Oxygen) in the periodic table. An example of a simple chemical equation looks like this: Reactants are written on the left side of the arrow while the products are located on the right side. It is a composition of both reactants and products, separated by an arrow (chemical reaction arrow), which indicates that a chemical reaction is occurring.
