I-Permutation: Imiqondo Eyisisekelo kanye Nezicelo I-Permutation ingumqondo obalulekile kwizibalo, ikakhulukazi kuma-combinatorics. Kalula nje, i-permutation iwukuhlelwa kabusha kwezinto kusethi. Kulesi sihloko, sizohlola ngokujulile umqondo oyisisekelo we-permutation, amafomula ahlobene nawo, kanye nezinye zezinhlelo zokusebenza zayo empilweni yansuku zonke kanye nasemikhakheni eyahlukene yesayensi. Imiqondo Eyisisekelo… Funda kabanzi
Amandla Ama-Acid Nezisekelo: Ukuqonda Izisekelo Zekhemistri Ama-Acid nezisekelo kuyizigaba ezimbili zamakhemikhali ezibalulekile ekusabeleni okuningi kwamakhemikhali, kanye nasekuphileni kwansuku zonke. Kusukela kusisombululo se-asidi ebhethrini lemoto kuya esisekelweni esisensipheni, adlala indima ebalulekile engenakunakwa. Kodwa-ke, yini eyenza into ibe yi-asidi noma isisekelo, … Funda kabanzi
Imithetho Yokugcwalisa Isikhala Kuzibalo Imithetho yokugcwalisa isikhala, eyaziwa nangokuthi i-permutations kanye nokuhlanganiswa, iyimiqondo eyisisekelo kumathuba kanye nezibalo. Ivumela ukuthi sibale inani lezindlela ezahlukene zokuhlela noma ukukhetha iqoqo lezinto. Kulesi sihloko, sizohlola imiqondo eyisisekelo, izinhlelo zokusebenza, kanye nezibonelo zangempela zemithetho yokugcwalisa isikhala. … Funda kabanzi
Amandla Esisekelo Se-Acid kanye ne-pH Ama-acid kanye nezisekelo kuyimibono emibili eyisisekelo kumakhemikhali edlala indima ebalulekile ekuphenduleni kwamakhemikhali ahlukahlukene kanye nezinqubo zokuphila. Ukuqonda amandla e-acid kanye nesisekelo, kanye nokukala i-pH, kubalulekile kokubili ezimweni zelebhu kanye nokusetshenziswa kwansuku zonke. Lesi sihloko sizohlola amandla e-acid kanye nesisekelo ngokujulile, imiqondo… Funda kabanzi
I-Combinatorics: Isayensi Ethakazelisayo Yokubala Kwezibalo I-Combinatorics igatsha lezibalo elifunda ukuthi ungabala kanjani, uhlele, uhlele, futhi uhlanganise izinto ngokwemithetho ethile. I-Combinatorics inezinhlelo zokusebenza ezibanzi emikhakheni eyahlukene njengesayensi yekhompyutha, izibalo, ukwenza ngcono, ngisho nasempilweni yansuku zonke. Lesi sihloko sizogxila ezimisweni eziyisisekelo, izindlela, kanye nezinye… Funda kabanzi
Ama-Acids nama-Base kaLewis: Ithiyori, Ukusetshenziswa, kanye Nokubaluleka Kwekhemistri Isingeniso Kukhemistri, imiqondo yama-asidi nama-base ibilokhu yaziwa futhi isetshenziswa amakhulu eminyaka. Kuye kwathuthukiswa imibono eyahlukahlukene ukuchaza izakhiwo kanye nokuziphatha kwama-asidi nama-base. Enye ithiyori eye yaba nomthelela omkhulu futhi yasetshenziswa kabanzi yithiyori yesisekelo se-asidi sikaLewis. Lo mqondo awugcini nje ngokwandisa izincazelo zama-asidi nama-base, … Funda kabanzi
Ubudlelwano Phakathi Kobude Be-Arc kanye Nendawo Yesigaba: Ezibalweni, ikakhulukazi ku-plane geometry, kunemibono ebalulekile ehilela imibuthano. Imiqondo emibili ebalulekile okuxoxwa ngayo njalo ubude be-arc kanye nendawo yesigaba. Ukuqonda kahle le mibono emibili kusenza sikwazi ukubala izici ezahlukahlukene zemibuthano, kungaba ezifundweni ezijwayelekile zezibalo, izinhlelo zokusebenza zobuchwepheshe, noma empilweni yansuku zonke. … Funda kabanzi
Ama-Brønsted-Lowry Acids kanye Nezisekelo Isingeniso Ithiyori yesisekelo se-acid iyingxenye ebalulekile yekhemistri enikeza ukuqonda okujulile kokusabela okuhlukahlukene kwamakhemikhali kanye nezakhiwo zama-compounds. Enye yethiyori ethandwa kakhulu futhi eyamukelwa kabanzi kukhemistri yesimanje yithiyori yesisekelo se-acid se-Brønsted-Lowry, eyaphakanyiswa ngokuzimela nguJohannes Nicolaus Brønsted waseDenmark kanye noThomas Martin Lowry wase … Funda kabanzi
