Chem 1 final reaction types

Synthesis Reaction

A + B ——> AB

A type of chemical reaction where two or more reactants combine to form a single product.

Decomposition Reaction

AB—→ A+B

Single Replacement Reaction

A + BC—→ AC+B

Double Replacement

AB+ CD—→ AD+CB

Redox Reaction

A+B—>A^+ +B^-

A chemical process involving the transfer of electrons between two species, resulting in a change in their oxidation numbers

Acid-base Reaction

Chemical process where an acid and base react and usually contains H^+ ions. It will usually result in water and salt.

Precipitation Reaction

a double replacement reaction that ends with at least one solid

Combustion Reaction

usually a hydrocarbon reacting with an oxidant like 02 which is usually (CO2) and (H2O)

NH4+

Ammonium

Oxidation

Loses electrons

Reduction

Gains electrons
