Question

What are some examples of chemical equations?

Answer 1

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 -> AB`
`2H_2 + O_2 -> 2H_2O`

Decomposition is the breakdown of one molecule into component parts.

`AB -> A + B`
`2KClO_3 -> 2KCl + 3O_2`

Single Displacement reactions exchange one element with a molecule.

`AB + C -> CB + A`
`CaCl_2 + Mg -> MgCl_2 + Ca`

Double Displacement reactions exchange two molecules.

`AB + CD -> AD + CB`
`NaCl + KNO_3 -> NaNO_3 + KCl`

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

`CH + O -> CO_2 + H_2O`
`C_3H_8 + 5O_2 -> 3CO_2 + 4H_2O`

and

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

`HA + BOH -> BA + H_2O`
`HCl + NaOH -> NaCl + H_2O`

I hope this was helpful.
