what are the six main types of chemical reactions

synthesis, decomposition, single replacement, double replacement, neutralization (acid-base), or combustion

define synthesis

- combination reaction


- two or more reactants (A and B) combine to produce a single product (AB)


- A + B > AB


define decomposition reaction

- reaction where compound is broken down into smaller compounds or separate elements


- reverse reaction of synthesis


- AB > A + B

define single repacement reaction

- A + BC > B + AC


- metal always goes with non-metal, and always comes first


define double replacement reaction

- involves two ionic solutions that react to produce two other ionic compounds


- AB(aq) + CD(aq) > AD(aq) + CD(s)

define precipitae

- insoluble solid that forms from a solution

how does double replacement reaction work

- the precipitate floats in the solution, then settles and sinks to the bottom


- the other compound may also form a precipitate, or may remain dissolved in solution

define neutralization (acid base) reaction

- when acid and base combine, neutralize each other


- acid and a base react to form a salt and water


- HA + BOH > AB + H2O


- a represents a negative ion, B represents a positive ion


define combustion

- rapid reaction of a compound or element with oxygen to form an oxide and produce heat


- always has CO2 and H2O as products


- CHO + O2 as reactants (subscripts vary)


- organic compound with oxygen
