About Chemical Reactions

In simple terms, a chemical reaction is a process that transforms one set of chemical substances into another. The substances involved in a chemical reaction are called reactants, and the substances produced by the reaction are called products. Chemical reactions are driven by changes in energy, typically the release or absorption of heat, light, or other forms of energy.

One of the simplest types of chemical reactions is a combination reaction, where two or more reactants combine to form a single product. For example, when magnesium reacts with oxygen to form magnesium oxide, the reactants are magnesium and oxygen, and the product is magnesium oxide.

Another type of chemical reaction is a decomposition reaction, where a single reactant breaks down into multiple products. For example, the breakdown of hydrogen peroxide into water and oxygen is a decomposition reaction.

A third type of chemical reaction is a displacement reaction, where one element is replaced by another element in a compound. For example, when zinc reacts with copper sulfate to form zinc sulfate and copper, the zinc displaces the copper in the compound.

Acid-base reactions are also a common type of chemical reaction. In these reactions, an acid donates a hydrogen ion (H+) to a base, which accepts the ion to form a salt and water. For example, the reaction between hydrochloric acid and sodium hydroxide to form sodium chloride (table salt) and water is an acid-base reaction.

Combustion

Combustion is an essential example of a chemical reaction. Simply put, combustion is a chemical reaction between a fuel and an oxidizing agent, usually oxygen, that releases energy in the form of heat and light.

The combustion process is the process by which fuels like coal, natural gas, gasoline, and wood are burned to produce energy.

KS3 Chemical Reactions

Chemical reactions are essential for KS3 and beyond. Our learning materials provide all the key information in intuitive and easily-digestible formats.
