Imikhakha Yendilinga: Umqondo, Ifomula, kanye Nokusetshenziswa Empilweni Yansuku Zonke Imikhakha yendilinga ingumqondo obalulekile ku-geometry futhi idlala indima ebalulekile ekusetshenzisweni okuhlukahlukene kwansuku zonke kanye nesayensi. Igama elithi "umkhakha" livela kwelesiJava, elisho umkhakha noma isigaba. Ngakho-ke, umkhakha wendilinga ungachazwa njengengxenye yendilinga eboshwe ngama-radii amabili... Funda kabanzi
Ama-Arrhenius Acids kanye Nezisekelo: Ukwembula Izisekelo Zekhemistri Ezweni lekhemistri, imiqondo yama-acids kanye nezisekelo iyizisekelo ezibalulekile ezisenza sikwazi ukuqonda ukusabela okuhlukahlukene kwamakhemikhali, kokubili ezindaweni zelebhu kanye nasempilweni yansuku zonke. Enye yezinkolelo-mbono zokuqala neziyisisekelo zokuhlukanisa ama-acids kanye nezisekelo yasungulwa nguSvante Arrhenius ngasekupheleni kwekhulu le-19. Le nkolelo-mbono, e… Funda kabanzi
Umbuthano: Ukwembula Imfihlakalo Nobuhle BeJiyomethri Umbuthano ungomunye wemilo yejiyomethri ejwayeleke kakhulu futhi uvame ukubhekwa njengophelele kakhulu. Ama-spinning disc, amasondo ajikelezayo, ngisho nemizila ecishe ibe sezingeni eliphezulu yamaplanethi konke kubonisa ukuba khona kwezindilinga. Kodwa-ke, kukhona into eyodwa yendilinga evame ukungatholi ukunakwa okwanele: i-arc… Funda kabanzi
Izakhiwo Nemiqondo Yama-Acid Nezisekelo Umqondo wama-acid nezisekelo ube yingxenye ebalulekile yekhemistri kusukela ezikhathini zasendulo. Lo mqondo awubalulekile nje kuphela ezifundweni zekhemistri zesikole kodwa futhi ubalulekile ezinhlotsheni ezahlukene zezimboni, ezolimo, ezokwelapha, kanye nezicelo zansuku zonke. Lesi sihloko sizohlola ngokugcwele izakhiwo nemibono yama-acid nezisekelo nge... Funda kabanzi
Ukuhlanganiswa Kokuguqulwa Komsebenzi Ezibalweni, ikakhulukazi ekufundweni kwemisebenzi, ukuguqulwa kuvame ukusetshenziselwa ukuguqula amagrafu kusuka kwesinye isimo kuya kwesinye. Lokhu kungenziwa ngokusebenzisa izindlela ezahlukene zokushintsha njengokushintsha (ukuhumusha), ukuzindla, ukwelula noma ukucindezela (ukulinganisa), kanye nokujikeleza. Lapho ukuguqulwa okuningi kusetshenziswa ngesikhathi esisodwa noma ngokulandelana, sikubiza ngokuthi inhlanganisela yokuguqulwa. Kulesi sihloko, sizo… Funda kabanzi
Izixazululo nama-Colloid: Ukubuka Okujulile Izinto Ezimbili Ezithakazelisayo Zamakhemikhali Kumakhemikhali, izixazululo nama-colloid kuyimiqondo emibili eyisisekelo evame ukuba yizihloko eziyinhloko ocwaningweni nasekusetshenzisweni okuhlukahlukene. Zombili zinezici ezihlukile kanye nezimo ezibalulekile ezimweni ezahlukene zesayensi nezisebenzayo. Lesi sihloko sifuna ukujula ezixazululweni kanye… Funda kabanzi
Ukujikeleza Kwezibalo: Ukuletha Ukuqonda Okuguquguqukayo KuJiyomethri Isingeniso Kuzibalo, ukujikeleza kungenye yezinguquko eziyisisekelo nezibaluleke kakhulu, ikakhulukazi kujiyomethri. Ukujikeleza akugcini nje ngokuba nezicelo kuzibalo ezihlanzekile kodwa futhi kunemiphumela ejulile kwisayensi nobunjiniyela. Lesi sihloko sihlose ukuhlola umqondo wokujikeleza kwezibalo, ukuthi kusebenza kanjani, nokuthi ungasetshenziswa kanjani.
Imibuzo Eyisibonelo Exoxa Ngokulingana Kwamakhemikhali Embonini Ukulingana kwamakhemikhali kuwumqondo obalulekile kumakhemikhali futhi kusebenza kakhulu emikhakheni eyahlukene yezimboni. Ekuphenduleni kwamakhemikhali, ukulingana kwenzeka lapho izinga lokusabela phambili lilingana nezinga lokusabela okuphambene, ukuze ukugxila kwama-reactants nemikhiqizo kuhlale kungaguquki ngokuhamba kwesikhathi. Izimboni eziningi, njengezemithi, amakhemikhali kaphethroli, kanye nokucubungula... Funda kabanzi
Ukwanda Kwezibalo: Ukushintsha Usayizi Ngaphandle Kokushintsha Isimo Isingeniso Ezibalweni, umqondo wokwanda udlala indima ebalulekile, ikakhulukazi ku-geometry. Ukwanda, noma ukuguqulwa okulinganayo, inqubo yokukhulisa noma ukunciphisa into ngaphandle kokushintsha isimo sayo sokuqala. Le nqubo ihilela ukusebenzisa isikali esithile ukukhulisa noma ukunciphisa yonke into ngokulinganayo. Lesi sihloko sizoxoxa ngomqondo, ukusetshenziswa, kanye nezibonelo… Funda kabanzi
Imibuzo Eyisibonelo kanye Nengxoxo Ngokushintsha Kokulingana Ukushintsha kokulingana kuyisihloko esibalulekile kumakhemikhali, ikakhulukazi ocwaningweni lokulingana kwamakhemikhali. Isimiso esiyinhloko esichaza ukushintsha kokulingana yiSimiso sikaLe Chatelier, esithi: "Uma uhlelo olusesimweni sokulingana lubhekana noshintsho (ukucindezeleka), uhlelo luzolungisa ukuze lunciphise umphumela woshintsho futhi lufinyelele esimweni...
