Ukusetshenziswa Kwama-Test Tubes Elabhorethri Ama-test tubes angenye yezingcezu zengilazi ezivame kakhulu ezitholakala emalabhorethri, kokubili esikoleni nasekhempasini, kanye nasemalabhorethri ocwaningo kanye nezimboni. Ukuma kwawo kulula: isilinda eside esinesisekelo esiyindilinga kanye ne-top evulekile. Nakuba kubonakala kungabalulekile, ama-test tubes adlala indima ebalulekile emisebenzini eyahlukene yelabhorethri kanye nokuhlaziya ngoba avumela... Funda kabanzi

Izinzuzo Nezingozi Zezibulala-zinambuzane Zamakhemikhali Izibulala-zinambuzane zamakhemikhali yizinto noma ingxube yamakhemikhali asetshenziselwa ukulawula izinto eziphilayo eziphazamisa izitshalo (i-OPT) njengezinambuzane, isikhunta, ukhula, amagundane, nezinye izinambuzane. Emikhubeni yezolimo yanamuhla, izibulala-zinambuzane zivame ukubhekwa "njengezisindisa impilo" ngoba zingavimbela ukulimala kwezitshalo ngokushesha. Kodwa-ke, ukusetshenziswa kwezibulala-zinambuzane zamakhemikhali nakho kunemiphumela... Funda kabanzi

Ukusabela Kwamakhemikhali Empilweni Yansuku Zonke Ukusabela kwamakhemikhali inqubo lapho into ishintsha ibe yinto entsha enezakhiwo ezahlukene. Lolu shintsho lwenzeka ngoba ama-athomu akha into ahlelwa kabusha: izibopho zamakhemikhali ezindala ziyaphulwa, bese kwakheka ezintsha. Nakuba igama elithi "ukusabela kwamakhemikhali" lizwakala lingokwesayensi, empeleni sibhekana nazo nsuku zonke—kusukela ekuphekeni kwasekuseni kuya ekuhlanzeni indlu kuya... Funda kabanzi

Umphumela we-pH Kumsebenzi We-Enzyme Ama-enzyme angama-molecule ezinto eziphilayo—ngokuvamile amaprotheni—asebenza njengezinto ezibangela ukusabela kwamakhemikhali ezintweni eziphilayo. Ngaphandle kwama-enzyme, ukusabela okuningi kwe-metabolic bekuzoqhubeka kancane kangangokuthi bekungeke kukwazi ukusekela impilo. Kodwa-ke, ikhono lama-enzyme lokusheshisa ukusabela alisebenzi ngendlela “engaxhomekeki ezimweni”. Umsebenzi we-enzyme uthonywa kakhulu yizici zemvelo, futhi… Funda kabanzi

Indima Yekhemistri Kwezolimo Ezolimo bezilokhu zingomunye wemikhakha ebaluleke kakhulu empilweni yomuntu kusukela ezikhathini zasendulo. Amandla abantu okukhulisa nokuvuna izitshalo ayisisekelo sempucuko kanye nentuthuko yomphakathi wanamuhla. Ekubhekaneni nezinselele zezolimo zanamuhla, njengokukhula kwabantu emhlabeni wonke, ukuguquka kwesimo sezulu, kanye nokulinganiselwa kwezinsizakusebenza, ikhemistri idlala indima ebalulekile ekusekeleni...

Indlela Yokubala Okuqukethwe Kwamanzi Esibonelweni Okuqukethwe komswakama kuyipharamitha ebalulekile okufanele uyiqonde ezimbonini ezahlukahlukene, kusukela kwezolimo nokudla kuya kwezemithi kanye nokwakha. Okuqukethwe komswakama kuthinta ngqo ikhwalithi, isikhathi sokuphelelwa yisikhathi, kanye nokusetshenziswa komkhiqizo noma izinto. Ngakho-ke, ukwazi nokulawula okuqukethwe komswakama kubalulekile.

Ayini Amaqembu Asebenzayo ku-Organic Chemistry? I-Organic chemistry iyigatsha le-chemistry elifunda isakhiwo, izakhiwo, ukwakheka, ukusabela, kanye nokuhlanganiswa kwamakhemikhali e-organic aqukethe ikhabhoni. Ku-organic chemistry, umqondo wamaqembu asebenzayo ubalulekile ekuqondeni umehluko wezakhiwo kanye nokusebenza kwamakhemikhali ahlukahlukene e-organic. Iqembu elisebenzayo yiqembu lama-athomu ngaphakathi kwe-molecule elinomthwalo wemfanelo… Funda kabanzi

Ukusabela Kwamakhemikhali Okwenzeka Emabhethrini Amabhethri abe ngenye yezinto ezintsha ezibaluleke kakhulu emlandweni wesintu, asebenzisa amadivayisi aqala emawashini kuya ezimotweni zikagesi. Isihluthulelo sokusebenza kwebhethri ukusabela kwamakhemikhali okwenzeka ngaphakathi kwalo. Lesi sihloko sizoxoxa ngokusabela kwamakhemikhali okuyisisekelo sokusebenza kwezinhlobo ezahlukene zamabhethri. Umlando Omfushane… Funda kabanzi

Ubudlelwano Phakathi Kokushisa Nokucindezela Kwegesi Isingeniso Imibono yokushisa nokucindezela yimibono emibili eyisisekelo yemvelo evame ukusetshenziswa esifundweni se-thermodynamics kanye ne-fluid mechanics. Ubudlelwano phakathi kokushisa kwegesi nokucindezela kuyisici esibalulekile okufanele siqondwe emikhakheni ehlukahlukene yesayensi nobuchwepheshe, okuhlanganisa ubunjiniyela bamakhemikhali, i-meteorology, kanye ne-physics. Lesi sihloko sizochaza… Funda kabanzi

Ukusetshenziswa kwe-Physical Chemistry embonini I-physical chemistry iyigatsha le-chemistry eligxile ekuqondeni izakhiwo kanye nokuziphatha kwezinto ngokusebenzisa imiqondo yemvelo kanye nezimiso eziyisisekelo ze-physics. Embonini, i-physical chemistry idlala indima ebalulekile ezinqubweni ezahlukene zokukhiqiza, ukusungula izinto ezintsha, kanye nokuthuthukiswa komkhiqizo. Lesi sihloko sizochaza okunye kokusetshenziswa okubalulekile kwe-physical chemistry embonini, kusukela... Funda kabanzi
