In a chemical reaction, the molecular make-up of a chemical compound changes. One type of chemical reaction is an oxidation reduction reaction, or redox reaction. In this reaction, the chemical species change because electrons are transferred from one reactant to another. ...
In oxidation and reduction chemistry, an oxidizing agent is a substance that is reduced in a chemical reaction, thereby causing another substance to be oxidized. Common oxidizing agents include oxygen (O2), which provides the origin of the term "oxidation", hydrogen peroxide (H2O2), ozone (O3)...
What is a thermal decomposition reaction? How does a combination reaction differ from a decomposition reaction? What happens to the reactants in a chemical reaction? What are the differences between decomposition reactions and combination reactions?
A cathode attracts cations (positive ions) and undergoes reduction, whereas an anode attracts anions (negative ions) and is the site of oxidation.

is unchanged, or a nuclear reaction, in which the composition of the atomic nucleus changes. In a chemical reaction, the atomic nucleus is untouched, but electrons may be transferred or shared to break and form chemical bonds. In both physical changes andchemical changes(reactions), the number...
reactions could be explained, scientists realized oxidation and reduction occur together, with one species losing electrons (oxidized) and another gaining electrons (reduced). A type of chemical reaction in which oxidation and reduction occurs is called a redox reaction, which stands for reduction-...
A reaction may involve multiple processes, and some of these may release heat, but as long as a reaction involves a net reduction in temperature, the reaction is endothermic. It's possible for this to happen because a chemical reaction always proceeds in a way that increases entropy. By cont...
Oxidation is a key part of redox reactions. Oxidation and reduction processes are essential in battery operation. 6 Oxidization Oxidization can mean the reaction of a substance with oxygen. The slow oxidization of wood is part of its natural decay process. 3 Oxidation Oxidation can involve th...
