Le nkolelo iyithuluzi elibalulekile lamakhemikhali ukuqonda isakhiwo sama-molecule kanye nezakhiwo zamakhemikhali ezahlukahlukene kanye… Funda kabanzi
Ukusetshenziswa Kwamagesi Ahloniphekile Ekuphileni Amagesi ahloniphekile ayiqembu lezinto zamakhemikhali kuthebula lezinto ezihlala isikhathi eside eliqukethe i-helium (He), i-neon (Ne), i-argon (Ar), i-krypton (Kr), i-xenon (Xe), kanye ne-radon (Rn). Lawa magesi aziwa ngokusabela kwawo kwamakhemikhali okuphansi kakhulu, ngakho-ke avame ukubizwa ngokuthi amagesi angangenisi. Empilweni yansuku zonke, amagesi ahloniphekile anezindlela eziningi zokusetshenziswa… Funda kabanzi
Indlela Yokwenza Igrafu Yezinga Lokusabela Igrafu yezinga lokusabela iyithuluzi elisebenza kahle kakhulu lokuhlaziya nokuqonda ukuthi ukusabela kwamakhemikhali kuqhubeka kanjani ngokuhamba kwesikhathi. Sisebenzisa le grafu, singalandelela izinguquko ekuqoqweni kwama-reactants noma imikhiqizo ekusabeleni kwamakhemikhali futhi sichaze ulwazi olubalulekile oluhlukahlukene njengezinga lokusabela kanye nendlela yokusabela. Lesi sihloko sizohlinzeka ngomhlahlandlela wesinyathelo ngesinyathelo… Funda kabanzi
Umsebenzi Wezikhuthazi Ekuphenduleni Kwamakhemikhali I-catalyst yinto esheshisa izinga lokusabela kwamakhemikhali ngaphandle kokudliwa unomphela ekusabela. Umqondo we-catalysis udlala indima ebalulekile ezicini ezahlukene zokuphila kwanamuhla, kusukela ekuthuthukisweni kwemithi kuya kubuchwepheshe bamandla ahlanzekile. Kulesi sihloko, sizoxoxa ngemisebenzi ehlukahlukene yezikhuthazi ekuphenduleni kwamakhemikhali kanye nemiphumela yazo… Funda kabanzi
Ayini Ama-electron e-Valence? Isingeniso Kumakhemikhali, igama elithi "ama-electron e-valence" liwumqondo oyisisekelo obalulekile ukuwuqonda. Ama-electron e-Valence awagcini nje ngokudlala indima ebalulekile ekunqumeni izakhiwo zamakhemikhali zento kodwa futhi athonya ukusabela kwamakhemikhali kanye nokuzinza kwama-compounds. Lesi sihloko sizoxoxa ngokujulile ngokuthi ayini ama-electron e-valence, ukuthi kungani ebalulekile, nokuthi... Funda kabanzi
Izakhiwo Ezihlanganisiwe Zezixazululo Ze-Electrolyte Isingeniso Izakhiwo ezihlanganisiwe zezixazululo yizakhiwo ezincike kuphela enanini lezinhlayiya ezincibilikayo ku-solvent ethile, kungakhathaliseki uhlobo noma uhlobo lwamakhemikhali lwalezo zinhlayiya. Izixazululo ze-Electrolyte zinezici ezihlukile ngoba ziqukethe i-solutes engenza i-ion ibe yi-ion, ikhiqize ama-ion amahle nangalungile. Le nqubo ihlukile... Funda kabanzi
Umehluko Phakathi Kwezibopho Ze-Covalent Ne-Ionic: Isibuyekezo Esijulile Izibopho zamakhemikhali zingamandla ahlanganisa ama-athomu ndawonye kuma-compound amakhemikhali. Izinhlobo ezimbili ezivame kakhulu zezibopho yi-covalent kanye ne-ionic. Nakuba zombili zisebenza ekuqiniseni ama-athomu kuma-compound, izindlela kanye nezakhiwo eziyisisekelo zohlobo ngalunye lwesibopho zihluka kakhulu. Lesi sihloko sihlose uku… Funda kabanzi
Izici Ezithinta Izinga Lokusabela Ukusabela kwamakhemikhali inqubo lapho into eyodwa noma eziningi zishintsha khona ukuze zenze into eyodwa noma eziningi ezintsha. Akuzona zonke izindlela zamakhemikhali ezenzeka ngesivinini esifanayo; ezinye zingashesha kakhulu, njengokuqhuma, kanti ezinye zingahamba kancane kakhulu, njengokugqwala kwensimbi. Izici ezahlukahlukene zithinta izinga lokusabela kwamakhemikhali… Funda kabanzi
Kuyini Ukusabela Kwe-Redox? Isingeniso Ezweni le-chemistry, izinqubo eziningi zemvelo nezokwenziwa zidlala indima ebalulekile empilweni yansuku zonke. Esinye isenzakalo esibalulekile samakhemikhali ukusabela kwe-redox. Igama elithi "redox" limelela izinqubo ezimbili ngesikhathi esisodwa: ukunciphisa kanye nokubola. Lesi sihloko sizochaza ngokuningiliziwe ukuthi ukusabela kwe-redox kuyini, kwenzeka kanjani, nokubaluleka kwako… Funda kabanzi
