Ama-hydrocarbon angahlukaniswa ngokusekelwe... Funda kabanzi
Ukuhlukile kwe-Athomu Yekhabhoni I-athomu yekhabhoni ingenye yezinto ezivelele kakhulu kuthebula le-periodic, ikhombisa ukuhlukile okuphawulekayo ekhonweni layo lokwakha izakhiwo zama-molecule ezahlukahlukene eziyinkimbinkimbi nezizinzile. I-Carbon (C) iyisici esinenombolo ye-athomu 6, okusho ukuthi inama-proton ayisithupha ku-nucleus yayo ye-athomu. Ngaphezu kwalokho, ikhabhoni inama-electron ayisithupha, asatshalaliswa… Funda kabanzi
Ama-hydrocarbon: Isisekelo Se-Chemistry Yanamuhla Isingeniso Ama-hydrocarbon ayizinto eziphilayo ezakhiwe ngama-athomu e-carbon (C) kanye ne-hydrogen (H). Njengezingxenye eziyinhloko zamafutha asetshenziswayo kanye nezinto zokugcoba, ama-hydrocarbon adlala indima ebalulekile empilweni yanamuhla. Lesi sihloko sizochaza izici ezahlukene zama-hydrocarbon, kusukela esakhiweni sawo kanye nezinhlobo zawo kuya ekusetshenzisweni kwawo kwezimboni kanye nomthelela emvelweni. … Funda kabanzi
Ukuhlanzeka Kwamaphesenti: Ukubaluleka Kwawo kanye Nendlela Yokubala Ukuhlanzeka kwamaphesenti kuwumqondo obalulekile emikhakheni ehlukahlukene yesayensi, kusukela kumakhemikhali okuhlaziya kuya embonini yezemithi. Ukuqonda ukuthi kuyini ukuhlanzeka kwamaphesenti nokuthi ungakubala kanjani kuyikhono eliyisisekelo elivame ukuba libalulekile ekusebenzeni kwelabhorethri, ekukhiqizweni kwamakhemikhali, nasekulawulweni kwekhwalithi. Lesi sihloko sizochaza ngokujulile… Funda kabanzi
Amaphesenti Okukhiqiza: Ukubaluleka Kokulinganisa Ukusebenza Kahle Nokukhiqiza Amaphesenti okukhiqiza ngokuvamile ayisibonakaliso esibalulekile emikhakheni eyahlukahlukene, kusukela ekukhiqizeni kuya emfundweni, ezempilo, kanye nasebhizinisini. Ukuchaza amaphesenti okukhiqiza njengendlela yokulinganisa ukusebenza kahle kanye nokukhiqiza akugcini nje ngokunikeza ukuqonda ngokusebenza kwamanje kodwa futhi kwenza kube nokuthuthuka okuqhubekayo ezinqubweni nasemisebenzini. Lesi sihloko sizochaza umqondo… Funda kabanzi
I-Limitting Reagent: Indima Yayo Ebalulekile Ekuphenduleni Kwamakhemikhali Ezweni le-chemistry, ukuqonda umqondo we-limiting reagent kubalulekile, kokubili kubafundi nabacwaningi abasebenza nge-chemical reactions elabhorethri. I-limiting reagent idlala indima ebalulekile ekunqumeni inani lomkhiqizo ongakhiqizwa ekusabela kwamakhemikhali. Lesi sihloko sizoxoxa ngokuningiliziwe ukuthi iyini i-limiting reagent...

Amafomula Ama-Molecular kanye Namafomula Aqanjiwe: Izisekelo kanye Nokusetshenziswa Kwe-Chemistry I-Chemistry, njengesayensi efunda izakhiwo, isakhiwo, kanye nokwakheka kwezinto, ixhumene ngokungenakuhlukaniswa nemibono eyisisekelo efana namafomula ama-molecule kanye namafomula aqanjiwe. Zombili zisebenza njengezindlela zokuveza ulwazi lwamakhemikhali ngokufushane nangokucacile. Kodwa ayini ngempela amafomula ama-molecule kanye namafomula aqanjiwe? Futhi… Funda kabanzi
Umqondo We-Mole: Isisekelo Esiyisisekelo Se-Chemistry Emhlabeni we-chemistry, kunemibono eminingi ebalulekile esisiza siqonde ukusabela kanye nokusebenzisana phakathi kwezinto zamakhemikhali. Omunye wemibono eyisisekelo nebalulekile kakhulu umqondo we-mole. Kulesi sihloko, sizochaza ngokuningiliziwe ukuthi iyini i-mole, isetshenziswa kanjani, nokuthi kungani ibaluleke kangaka ku-chemistry. Funda kabanzi
Ukuqonda i-Stoichiometry I-Stoichiometry igatsha le-chemistry elibhekene nokubalwa kwenani lama-reactants kanye nemikhiqizo ekuphenduleni kwamakhemikhali. Igama elithi 'stoichiometry' livela emagameni esiGreki athi 'stoicheion' (isici) kanye nelithi 'metron' (isilinganiso), okusho ngokwezwi nezwi ukulinganiswa kwezinto. Izimiso eziyisisekelo ze-stoichiometry zihilela imithetho eyisisekelo ye-chemistry, njengoMthetho Wokulondolozwa Kwesisindo, othi isisindo esiphelele sento ethile kuvolumu ethile silingana nesisindo esiphelele sento ethile kuvolumu ethile.
