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 |
