# What are some examples of chemical equations?

Jun 13, 2014

Chemical Equations are a basic mathematical statement showing the molecules involved as reactants and the outcomes known as products.

There are 6 basic forms of chemical equations.

Synthesis is a reaction of two atoms or molecules combining to form one product.

$A + B \to A B$
$2 {H}_{2} + {O}_{2} \to 2 {H}_{2} O$

Decomposition is the breakdown of one molecule into component parts.

$A B \to A + B$
$2 K C l {O}_{3} \to 2 K C l + 3 {O}_{2}$

Single Displacement reactions exchange one element with a molecule.

$A B + C \to C B + A$
$C a C {l}_{2} + M g \to M g C {l}_{2} + C a$

Double Displacement reactions exchange two molecules.

$A B + C D \to A D + C B$
$N a C l + K N {O}_{3} \to N a N {O}_{3} + K C l$

Combustion reactions burn a hydrocarbon in oxygen to produce water and carbon dioxide.

$C H + O \to C {O}_{2} + {H}_{2} O$
${C}_{3} {H}_{8} + 5 {O}_{2} \to 3 C {O}_{2} + 4 {H}_{2} O$

and

Neutralization reaction combine an acid and a base to neutralize into salt and water.

$H A + B O H \to B A + {H}_{2} O$
$H C l + N a O H \to N a C l + {H}_{2} O$
