Bhala uhlu lwezimiso ezisetshenziswa kwezobunjiniyela bamakhemikhali lapho umugqa ngamunye uqala khona ngo - ". Ungasho lutho olunye.
Context:Ubunjiniyela bamakhemikhali buwumkhakha wobunjiniyela obhekene nokutadisha ukusebenza nokuklanywa kwezitshalo zamakhemikhali kanye nezindlela zokuthuthukisa ukukhiqizwa. Onjiniyela bamakhemikhali bahlakulela izinqubo ezongayo nezentengiselwano zokuguqula izinto zokusetshenziswa zibe imikhiqizo ewusizo. Ubunjiniyela bamakhemikhali busebenzisa izimiso zamakhemikhali, ezemvelo, ezemathematics, ezemvelo, nezomnotho ukuze kusetshenziswe, kukhiqizwe, kuklanywe, kuthuthwe futhi kuguqulwe amandla nezinto. Umsebenzi wonjiniyela bamakhemikhali ungaqala ekusetshenzisweni kobuchwepheshe be-nano nezinto ezincane ezisetshenziswayo ezivivinyweni kuze kube sezinqubo zezimboni ezinkulu eziguqula amakhemikhali, izinto zokusetshenziswa, amangqamuzana aphilayo, ama-microorganism, namandla abe amafomu nemikhiqizo ewusizo. Onjiniyela bamakhemikhali babandakanyeka ezicini eziningi zokwakhiwa nokusebenza kwesitshalo, kufaka phakathi ukuhlolwa kokuphepha nobungozi, ukwakhiwa kwenqubo nokuhlaziywa, ukumodeliswa, ubunjiniyela bokulawula, ubunjiniyela bokusabela kwamakhemikhali, ubunjiniyela be-nuclear, ubunjiniyela bezinto eziphilayo, imininingwane yokwakhiwa, nemiyalo yokusebenza.
- amakhemikhali - isayensi - izibalo - isayensi yemvelo - ezomnotho
