Based on: Ramírez & Regalado (2016)
Synthesis reactions: are those in which two elements react and one compound is obtained.
Synthesis and Addition Reactions
Ramírez, V. (2026)
Addition reactions: are those in which two compounds, or an element and a compound, react and a single compound is obtained.
A + B C
A chemical reaction is the process in which a system characterized by the physical and chemical properties of the substances that constitute it undergoes a change.Chemical reactions involve a reorganization of atoms at a microscopic level to form new molecules. Bonds are broken and atoms form bonds in another way.

Do the foods you eat, the fibers in your clothing, and the plastic in soft drinks have anything in common? All of them occur when the atoms of substances are rearranged to form different ones, this is called: “Chemical reaction”
Did you know?
When an element reacts with a compound, the element replaces another element in the compound.
Single Replacement Reaction
Ramírez, V. (2016)
A + BC AC + B
When two compounds react, two compounds are produced, through an exchange of ions between the substances.
Double Replacement Reaction
AB + CD AD + CB
A special type of double substitution reactions are neutralization reactions. In this reaction, an acid reacts with a base to form salt plus water. This reaction allows acids to be neutralized, for example when you have heartburn.
Neutralization Reactions
They are those in which a compound, by the action of heat or energy, is decomposed into two or more elements or compounds..
Decomposition Reactions
Ramírez, V. (2026)
AB A + B
Common symbols used in chemical reactions:
CnH2n+2 + O2 CO2 + H2O
Combustion Reactions
Burning organic compounds, such as alkanes, always produces carbon dioxide + water.
CH4 + 2O2 CO2 + 2H2O
