Isilinganiso Sedatha Eqoqwe: Umqondo, Ukubala, kanye Nokusetshenziswa Isingeniso Isilinganiso, noma lokho esivame ukukwazi njengesilinganiso, singenye yezindlela ezisetshenziswa kakhulu zokulinganisa ukuthambekela okuphakathi kwezibalo. Kudatha eqoqwe, ukubala isilinganiso akulula njengokubala isilinganiso samaphuzu edatha ngamanye ngoba kuhilela ukuhlanganisa idatha ngezigaba noma amakilasi athile. Lesi sihloko sizohlola ngokujulile… Funda kabanzi
Imibuzo Nengxoxo Yezibonelo: Ukuqonda i-Stoichiometry I-Stoichiometry iyigatsha lekhemistri elifunda ubuningi bezinto ezihilelekile ekuphenduleni kwamakhemikhali. Igama elithi 'stoichiometry' ngokwalo livela kwelesiGriki elithi "stoicheion," elisho i-element, kanye nelithi "metron," elisho isilinganiso. I-Stoichiometry igxile esilinganisweni sama-moles, isisindo, ivolumu, kanye nezinhlayiya ekusabela kwamakhemikhali. I-Stoichiometry ibalulekile kukhemistri ngoba... Funda kabanzi
Ukusebenzisa Izinga Lokuba Sesimeni Esiphakathi: Izinto Ezibalulekile kanye Nezicelo. Izinga lokuba sesimeni esiphakathi ziyimiqondo ebalulekile kuzibalo ezibhekisela kusethi yamanani abonisa phakathi kwesethi yedatha. Inhloso yazo ukunikeza umbono jikelele wamanani avame ukuvela noma isikhungo sokusatshalaliswa kwedatha. Izinga lokuba sesimeni esiphakathi zibalulekile ekuhlaziyweni kwedatha nasekucwaningweni ngoba zisivumela ukuthi sibone ukumelwa… Funda kabanzi
Imibuzo Eyisibonelo Nge-Stoichiometry: Ukuqonda Izisekelo Nokusetshenziswa Kwayo I-Stoichiometry iyigatsha le-chemistry elifunda izilinganiso zobuningi phakathi kwama-reactants nemikhiqizo ekusabeleni kwamakhemikhali. Empeleni, i-stoichiometry ihlobene eduze nomthetho wokulondolozwa kwesisindo, owaphakanyiswa okokuqala ngu-Antoine Lavoisier. Le sayensi yakha isisekelo semiqondo eminingi kumakhemikhali, kusukela… Funda kabanzi
Isilinganiso: Isilinganiso noma Isilinganiso Isilinganiso noma isilinganiso singenye yemiqondo eyisisekelo kakhulu kwizibalo. Sivame ukusetshenziswa emikhakheni ehlukahlukene, kusukela kwezemfundo nakwezomnotho kuya kwisayensi. Kulesi sihloko, sizoxoxa ngokujulile ukuthi iyini isilinganiso, ukuthi singabalwa kanjani, nokuthi sihunyushwa futhi sisetshenziswa kanjani empilweni yansuku zonke. Iyini i-mean? Isilinganiso yinani… Funda kabanzi
Imibuzo Nengxoxo Yesibonelo Sokubopha Phakathi Kwama-molecule Ukubopha phakathi kwamangqamuzana kuyisihloko esibalulekile kumakhemikhali, ikakhulukazi ekuqondeni izakhiwo zomzimba nezamakhemikhali zento ethile. Izibopho eziphakathi kwamangqamuzana zifaka phakathi amandla okusabalala kweLondon, amandla e-dipole-dipole, kanye nezibopho ze-hydrogen. Ukuqonda kahle uhlobo ngalunye lwalezi zibopho nokuthi zihlangana kanjani kubalulekile ekubikezeleni ukuziphatha kwezinto ngaphansi kwezimo ezahlukahlukene. … Funda kabanzi
Imodi kanye neMedian: Incazelo kanye Nokusetshenziswa kuzibalo Izibalo ziyigatsha lezibalo elibhekene nokuqoqwa, ukuhlaziywa, ukuchazwa, ukwethula, kanye nokuhlela idatha. Kuzibalo, kunezindlela ezahlukene zokulinganisa ukuhlakazeka kanye nezincazelo eziyinhloko zedatha ezisetshenziselwa ukuhlaziya nokuqonda idatha. Ezimbili eziyisisekelo nezibalulekile yimodi kanye neMedian. Lesi sihloko… Funda kabanzi
Imibuzo Eyisibonelo Exoxa Ngezimo Zama-Molecular Isingeniso I-Chemistry yisayensi efunda ukuziphatha kwezinto kanye nezinguquko ezidlula kuzo. Umqondo owodwa obalulekile ku-chemistry ukuqonda ukuma kwama-molecule. Ukuma kwama-molecule kuthonya izakhiwo zomzimba nezamakhemikhali zama-compounds, njengephuzu lokuncibilika, iphuzu lokubila, kanye nomfutho womusi. Ukuma kwama-molecule nakho kudlala indima ebalulekile ekunqumeni ukusabela kwamakhemikhali... Funda kabanzi
Izilinganiso Zokuba Sesimeni Esiphakathi: Ukubaluleka Kokuqonda Ekuhlaziyweni Kwedatha. Emikhakheni eyahlukene yesayensi, ukuqonda kahle idatha kuyisisekelo esibalulekile sokwenza izinqumo ezinembile nezinolwazi. Omunye wemibono ebalulekile ekuhlaziyweni kwedatha izilinganiso zokuba sesimeni esiphakathi. Izilinganiso zokuba sesimeni esiphakathi zinikeza umbono ojwayelekile wendawo ephakathi nendawo yokusatshalaliswa kwedatha. Lesi sihloko sizohlola… Funda kabanzi
