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.

$A + B \to A B$ $A + B -> AB$
$2 H_{2} + O_{2} \to 2 H_{2} O$ $2H_2 + O_2 -> 2H_2O$

Decomposition is the breakdown of one molecule into component parts.

$A B \to A + B$ $AB -> A + B$
$2 K C l O_{3} \to 2 K C l + 3 O_{2}$ $2KClO_3 -> 2KCl + 3O_2$

Single Displacement reactions exchange one element with a molecule.

$A B + C \to C B + A$ $AB + C -> CB + A$
$C a C l_{2} + M g \to M g C l_{2} + C a$ $CaCl_2 + Mg -> MgCl_2 + Ca$

Double Displacement reactions exchange two molecules.

$A B + C D \to A D + C B$ $AB + CD -> AD + CB$
$N a C l + K N O_{3} \to N a N O_{3} + K C l$ $NaCl + KNO_3 -> NaNO_3 + KCl$

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

$C H + O \to C O_{2} + H_{2} O$ $CH + O -> CO_2 + H_2O$
$C_{3} H_{8} + 5 O_{2} \to 3 C O_{2} + 4 H_{2} O$ $C_3H_8 + 5O_2 -> 3CO_2 + 4H_2O$

and

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

$H A + B O H \to B A + H_{2} O$ $HA + BOH -> BA + H_2O$
$H C l + N a O H \to N a C l + H_{2} O$ $HCl + NaOH -> NaCl + H_2O$

I hope this was helpful.
