Izakhiwo Zomzimba Nezamakhemikhali Zama-Halogens: Ukubuka Okujulile Izinto EziseQenjini 17 Ama-halogens ayiqembu lezinto eziseQenjini 17 lethebula lezinto eziphindaphindwayo, eliqukethe i-fluorine (F), i-chlorine (Cl), i-bromine (Br), i-iodine (I), i-astatine (At), kanye ne-tenesine (Ts) yakamuva. Njengezinto ezingezona ezensimbi, ama-halogens anezakhiwo zomzimba nezekhemikhali ezihlukile ezenza... Funda kabanzi
Inqubo Yokwenza Ipulasitiki Ngezinhlanganisela Zemvelo: Ipulasitiki ingenye yezinto ezisetshenziswa kakhulu ezimbonini ezahlukahlukene nasempilweni yansuku zonke. Izakhiwo zayo ezilula, eziguquguqukayo, ezingangeni manzi, neziguquguqukayo zenza kube ukukhetha okuyinhloko kwezicelo eziningi, kusukela ekupakishweni kokudla kuya ezingxenyeni zezimboni ezisindayo. Kulesi sihloko, sizohlola inqubo yokwenza ipulasitiki… Funda kabanzi
Kuyini Ukusabela Okungaguquki? Ukusabela kwamakhemikhali kuyizinqubo eziyisisekelo kumakhemikhali ezichaza indlela izinto ezisabela ngayo ekwakheni imikhiqizo emisha. Phakathi kwezinhlobo ezahlukene zokusabela kwamakhemikhali, ukusabela okungaguquki kuyathakazelisa kakhulu. Lesi sihloko sizoxoxa ngokujulile ngokusabela okungaguquki, izindlela zazo, izibonelo, kanye nokubaluleka kwazo ekusetshenzisweni okuhlukahlukene. Ukuqonda Ukusabela Okungaguquki… Funda kabanzi
Ubudlelwano Phakathi Kokucindezela Nomthamo Wegesi Isingeniso Igesi ingenye yezinhlobo ezintathu zezinto esivame ukuzithola ezisizungezile, kanye noketshezi nezinto eziqinile. Zombili zinezakhiwo nezici ezihlukile. Ukuze siqonde ukuziphatha kwamagesi, kumele sihlole ezinye zezimiso eziyisisekelo zefiziksi kanye nekhemistri ezisekela wona. Ubuhlobo obubodwa obubaluleke kakhulu ku… Funda kabanzi
Izinzuzo Nokungalungile Kwemodeli Ye-athomu KaRutherford Imodeli ye-athomu kaRutherford, eyaphakanyiswa ngu-Ernest Rutherford ngo-1911, yayiyingqophamlando ekuthuthukisweni kwekhemistri kanye nefiziksi. Le modeli yavela ekuhlolweni kokusabalala kwezinhlayiya ze-alpha, okwaphonsela inselelo imodeli ye-athomu kaThomson endala. Kulesi sihloko, sizohlola izinzuzo nokungalungi kwemodeli ye-athomu kaRutherford… Funda kabanzi
Indlela Yokuhlukanisa I-Chromatography Isingeniso I-Chromatography ingenye yezindlela ezisebenza kahle kakhulu neziguquguqukayo zokuhlukanisa izingxube zamakhemikhali, ezisetshenziswa emikhakheni ehlukahlukene yesayensi kanye nemboni. Igama elithi "chromatography" livela kumagama esiGreki athi "chroma," okusho umbala, kanye nelithi "graphein," okusho ukubhala. Nakuba le ndlela yayisetshenziswa ekuqaleni ukuhlukanisa ama-compounds anemibala, namuhla i-chromatography ingasetshenziswa ukuhlukanisa... Funda kabanzi
Isakhiwo kanye Nomsebenzi Wamaprotheni Isingeniso Amaprotheni angama-molecule amakhulu, ayinkimbinkimbi adlala indima ebalulekile cishe kuyo yonke inqubo yezinto eziphilayo emzimbeni womuntu nakwezinye izinto eziphilayo. Aqukethe amaketanga amade ama-amino acid ahlanganiswe abe yizimo ezithile ezinobukhulu obuthathu, okuwenza akwazi ukwenza imisebenzi eyahlukahlukene. Kulesi sihloko, sizohlola isakhiwo… Funda kabanzi
Ukuqonda Ukusabela Kwamakhemikhali Okuvela Emothermic Nase-Endothermic Ukusabela kwamakhemikhali kuyizinto ezibalulekile esivame ukuhlangana nazo ekuphileni kwansuku zonke. Ukusabela kwamakhemikhali kwenzeka hhayi kuphela emalabhorethri kodwa nasezinqubweni ezahlukahlukene ezenzeka eduze kwethu, njengokupheka, ukushisa, ukushisa uphethiloli, ngisho nangaphakathi emizimbeni yethu. Ukusabela kwamakhemikhali kungahlukaniswa ngokusekelwe ezintweni ezahlukahlukene... Funda kabanzi
Izinhlobo zama-Isomers kuKhemistri Ama-Isomers angama-compounds anefomula efanayo yama-molecule kodwa ahlukile ngesakhiwo noma ekuhleleni kwama-athomu. Lesi simo singenye yezici ezithakazelisa kakhulu ze-organic kanye ne-inorganic chemistry ngoba lokhu kuhlukahluka kwesakhiwo kungakhiqiza ama-compounds anezakhiwo zomzimba nezamakhemikhali ezihluke kakhulu. Kunezinhlobo ezahlukene zama-isomers ezingahlukaniswa ngezigaba… Funda kabanzi
