I- izenzakalo zamakhemikhali yilezo lapho kwenzeka khona ushintsho ezintweni, ngokuvela kwezinto ezithile nokunyamalala kwezinye.
Cishe balalela njalo ukusabela kwamakhemikhali, okungazenzakalela noma kubangelwe ukuxuba izinto ezahlukahlukene nokuzibeka ezimweni ezithile ze izinga lokushisa, kusuka pHingcindezi, njll.
Ukuphendula okuyinhloko kwamakhemikhali kufana nenye yalezi zinhlobo ezilandelayo:
- Ukuhlanganiswa
- Ukubola
- Ukwengeza
- Ukufaka esikhundleni

Ukubaluleka
Izimo eziningi zamakhemikhali gcina impilo yabantu abaphilayo, njengoba ukugaya kubantu nasezilwaneni, i i-photosynthesis ezitshalweni nasekuphefumuleni kukho kokubili.
Enye inqubo yamakhemikhali ebaluleke kakhulu, ikakhulukazi empilweni ye- ama-microorganisms, yi ukuvutshelwa, okujwayele ukusetshenziselwa ukwenziwa kokudla okunjengoshizi, ama-yogurts, amawayini kanye nobhiya.
Empeleni konke ukukhula nokuthuthuka kwe- a umuntu ophilayo Ithobela amasignali amakhemikhali akhiqizwa kuyo, kwesinye isikhathi ivuselelwa yizakhi zemvelo.
Izibonelo zezinto zamakhemikhali
Kunezimo eziningi zezinto zamakhemikhali noma izinqubo ezifaka phakathi kwethu, nazi ezinye:
- Izinkuni zibola
- Ukushisa kwephepha
- Ukumelana namagciwane kwamagciwane
- Ubisi oluphenduka lube muncu
- Ukubulala amagciwane enxebeni ngotshwala
- Sebenzisa usawoti wezithelo ukulwa nesilungulela
- Ukushisa ikhandlela
- Ukujiya kwegazi
- Ukukhathala kwemisipha ngemuva kokuzivocavoca okukhulu
- Ukufa kwezinambuzane ngemithi yokubulala izinambuzane
- Ukuthola ushizi weRoquefort
- Ukuthola i-cider
- Ukuthola iyogathi
- Ukwenza umquba
- Ensilage
- Ukuthola i-bioethanol kusuka kuma-molasses
- Amathini amathini avuvukile
- Iqanda elibolile
- Ukugqwala kwe-grate
- Ukuthola i-biodiesel emafutheni esundu

Izimo zamakhemikhali embonini
Futhi embonini izenzakalo ezithile zamakhemikhali ziyisihluthulelo. Okokuqala, i- ukushisa kwe-hydrocarbon okufana nophethiloli, udizili noma uphalafini, wondla imishini ephatha izinqubo zezimboni ezingenakubalwa.
Ngakolunye uhlangothi, imboni yensimbi, iphepha, amapulasitiki, izinto zokwakha, upende, izidakamizwa, imikhiqizo yezolimo, njll., Isuselwa kuzimo ezahlukahlukene zamakhemikhali, njenge ingxubevange, i lashukumisa, i i-electrolysis nabanye abaningi.
Futhi kususelwa kulolu hlobo lwezimo izakhi ze- ukukhiqizwa kwemithombo emisha yamandla, njenge-biodiesel ne-bioethanol.

Ukuguqulwa kwamandla
Ezimweni zamakhemikhali kuvamile ukuthi kube khona ukuguqulwa kwamandla. Isibonelo, ukuthi amandla amakhemikhali aqukethwe yizibopho zemolekyuli ethile aguqulwa abe amandla kagesi noma akhishwe njengokushisa (lokhu kwenzeka ezimweni ezibabazekayo, njengalapho i-hydrochloric acid ixutshwe ne-zinc), noma ukuthi amandla alula ayabanjwa futhi aguqulwe abe amandla amakhemikhali.
Ezinye izinqubo zamakhemikhali badinga ukushisa Ukuze kwenziwe, babizwa nge-endothermic, abanye badinga i- ukutholakala kwama-catalysts noma ama-cofactors.
