What is a Combustion reaction?

A chemical reaction between substances, usually including oxygen and usually accompanied by the generation of heat and light in the form of flame.

Decomposition -A decomposition reaction can be defined as a chemical reaction in which one reactant breaks down into two or more products.

Synthesis - Synthesis reactions are reactions that occur when two different atoms or molecules interact to form a different molecule or compound.

Double replacement -A double replacement reaction is a type of chemical reaction that occurs when two reactants exchange cations or anions to yield two new products.

Single replacement -A single replacement reaction, sometimes called a single displacement reaction, is a reaction in which one element is substituted for another element in a compound.
