Imibuzo Nengxoxo Yesibonelo Se-Lewis Acid-Base Isingeniso Ukusabela kwe-acid-base kuyisihloko esiyisisekelo kukhemistri, esisetshenziswa kabanzi emikhakheni eyahlukene kanye nasezimbonini. Izincazelo eziningana zama-acid kanye nezisekelo zisetshenziswa kukhemistri, kufaka phakathi izincazelo ze-Arrhenius, i-Bronsted-Lowry, kanye ne-Lewis. Lesi sihloko sizogxila emqondweni wama-acid kanye nezisekelo ze-Lewis kanye… Funda kabanzi
I-Integral I-Integral ingumqondo oyisisekelo ekubaleni, ohlobene kakhulu nomqondo we-derivative. Ngenkathi i-derivative ichaza ushintsho emthambekeni we-curve endaweni ethile, i-integral, ngakolunye uhlangothi, ihlanganisa yonke indawo ngaphansi kwe-curve ngaphakathi kwesikhawu esithile. I-Integrals ingamathuluzi abalulekile kwizibalo, i-physics, ubunjiniyela, kanye neminye imikhakha eminingi. Lesi sihloko sizoxoxa ngalo mqondo… Funda kabanzi
Isibonelo Senkinga Yesisekelo Se-Acid EsiseBrønsted-Lowry Ama-asidi nezisekelo kuyimibono ebalulekile kumakhemikhali eye yathuthukiswa futhi yahlungwa ososayensi abaningi eminyakeni edlule. Enye yezinkolelo-mbono ezithandwa kakhulu yithiyori kaBrønsted-Lowry, eyaphakanyiswa nguJohannes Nicolaus Brønsted noThomas Martin Lowry ngo-1923. Le thiyori inikeza umbono obanzi wokuthi kanjani… Funda kabanzi
Ukusetshenziswa Kwezinto Ezivela Kuwo Emikhakheni Ehlukahlukene Yesayensi I-derivative ingumqondo oyisisekelo ku-calculus, owethulwa nguSir Isaac Newton noGottfried Wilhelm Leibniz ngasekupheleni kwekhulu le-17. Kumathematika, i-derivative imele izinga lokushintsha komsebenzi maqondana nenye yeziguquguquko zawo. Lo mqondo awuyona nje isisekelo semathematika uqobo kodwa futhi unezinhlelo zokusebenza ezibanzi ku… Funda kabanzi
Imibuzo Nezingxoxo Zesibonelo Se-Arrhenius Acid-Base Ama-asidi nezisekelo kuyimibono eyisisekelo kumakhemikhali. Enye yemibono eyaziwayo kakhulu yokuchaza ukuziphatha kwama-asidi nezisekelo ithiyori ye-Arrhenius. Ngokusho kwe-Arrhenius, i-asidi iyinhlanganisela ethi, uma incibilikiswa emanzini, ikhiqize ama-ion e-H⁺ (noma i-H₃O⁺), kuyilapho isisekelo siyinhlanganisela ethi, uma incibilikiswa emanzini, ikhiqize… Funda kabanzi
Amaphuzu Aphezulu Okubuyiselwa Okuncane Nokukhulu Kuzibalo kanye nokuhlaziywa, umqondo wamaphuzu aphakeme ubalulekile, kokubili emikhakheni eyahlukene yesayensi kanye nasekusetshenzisweni kwansuku zonke okusebenzayo. Amaphuzu aphakeme, abhekisela kumaphuzu akugrafu yomsebenzi lapho umsebenzi ufinyelela khona inani lawo eliphansi noma eliphezulu, adlala indima ebalulekile ekuboneni izici ezibalulekile ze… Funda kabanzi
Imibuzo Eyisibonelo Exoxa Ngezakhiwo Nemiqondo Yama-Acid Nezisekelo Izakhiwo nemibono yama-asidi nezisekelo ziyizihloko ezibalulekile kukhemistri, kanye nokusetshenziswa okubanzi emikhakheni eyahlukahlukene, okuhlanganisa imboni, ikhemisi, kanye ne-biochemistry. Ukuqonda imiqondo eyisisekelo kanye nokusetshenziswa kwezakhiwo ze-asid-base kubalulekile kubafundi nakubacwaningi. Lesi sihloko sizoxoxa ngemibuzo eminingana eyisibonelo mayelana... Funda kabanzi
Imisebenzi Ekhulayo, Imisebenzi Encishisiwe, kanye Nemisebenzi Emiyo: Ukuhlaziywa Nokusetshenziswa Kwezibalo, ikakhulukazi ekubaleni nasekuhlaziyeni, umqondo womsebenzi uyisisekelo esibalulekile esisivumela ukuthi sichaze futhi siqonde izici ezahlukahlukene zezehlakalo zemvelo nezishintshashintshayo. Isihloko esisodwa esithakazelisayo okufanele sixoxe ngaso ukwandisa imisebenzi, imisebenzi encishisiwe, kanye nemisebenzi emiyo. Lezi… Funda kabanzi
Izixazululo nama-Colloids: Izibonelo Nezingxoxo Izixazululo nama-colloids yizihloko ezimbili ezibalulekile kukhemistri ezibaluleke kakhulu ezicini eziningi zokuphila kwansuku zonke kanye nezicelo ezahlukahlukene zezimboni nezesayensi. Ikhono lokuqonda nokuhlaziya izixazululo nama-colloids liyikhono elibalulekile elidingekayo emikhakheni eminingi yokufunda. Kulesi sihloko, sizoxoxa ngezibonelo ezahlukahlukene… Funda kabanzi
Isilinganiso Somugqa Oqondile Esigoqweni Esibalweni, isibalo somugqa oqondile esigoqweni sidlala indima ebalulekile ekuqondeni izimo ezahlukahlukene, kokubili kwisayensi nobunjiniyela, kanye nasekusetshenzisweni kwansuku zonke.
