Uyini Umthetho KaRaoult KuKhemistri? Kukhemistri, ikakhulukazi ekufundweni kwezixazululo kanye nezakhiwo zomzimba zezingxube, kunomqondo obalulekile ovame ukusetshenziswa ukuchaza ukuthi ingcindezi yomhwamuko wento ishintsha kanjani uma ixutshwa nenye into. Lo mqondo waziwa ngokuthi uMthetho KaRaoult. Lo mthetho uyisisekelo sokuqonda izenzakalo ezahlukahlukene zansuku zonke kanye nezinqubo zezimboni,... Funda kabanzi
Ukuqonda Ukusabela Kwenuzi Nezibonelo Ukusabela kwenuzi kungenye yezinto ezibaluleke kakhulu kwifiziksi yesimanje ngoba kuhilela izinguquko ezenzeka ku-nucleus ye-athomu. Ngokungafani nokusabela kwamakhemikhali, okubandakanya ukudluliselwa noma ukuhlanganiswa kwama-electron ngaphakathi kwegobolondo le-athomu, ukusabela kwenuzi kwenzeka ngqo ku-nucleus ye-athomu, eyakhiwa ama-proton nama-neutron. Ngenxa yalokho, ukusabela kwenuzi kunga... Funda kabanzi
Amasu E-Thin Layer Chromatography Ekhemisi Isingeniso I-Thin Layer Chromatography (TLC) iyindlela yokuhlaziya evame kakhulu esetshenziswa emkhakheni wezokwelapha. Le ndlela yaziwa ngokulula kwayo, isivinini, kanye nokungabizi kakhulu, kanye nekhono layo lokunikeza ulwazi olubalulekile mayelana nokwakheka kwesampula. Emalabhorethri ezokwelapha, i-TLC ivame ukusetshenziswa kukho konke kusukela... Funda kabanzi
Umsebenzi Wamakhemikhali E-Carbohydrate Emzimbeni Ama-carbohydrate ayizinhlanganisela eziphilayo ezibalulekile empilweni yomuntu. Ekudleni, ama-carbohydrate afakiwe eqenjini lezakhamzimba ezinkulu, kanye namaprotheni namafutha, ngoba adingeka ngobuningi obukhulu ukusekela imisebenzi yomzimba. Ama-carbohydrate avame ukuhlotshaniswa "nemithombo yamandla," kodwa indima yawo empeleni ingaphezulu kakhulu... Funda kabanzi
Ukusetshenziswa Kwe-Centrifuge Emalabhorethri Ama-Centrifuge angamathuluzi abalulekile emalabhorethri ahlukahlukene, kusukela emalabhorethri emitholampilo, emalabhorethri ebhayoloji, kanye namalabhorethri ekhemistri kuya ezimbonini zemithi nezokudla. Asebenza ngesimiso samandla e-centrifugal, amandla akhiqizwa ukujikeleza okusheshayo okuhlukanisa izinhlayiya kusampula ngokusekelwe ekwehlukeni kobukhulu nobukhulu. … Funda kabanzi
Izinzuzo Nezingozi Zama-Formalin Compounds I-Formalin iyisisombululo esiqukethe i-formaldehyde emanzini, ngokuvamile equkethe cishe i-formaldehyde engu-37%, ngokuvamile enenani elincane le-methanol elengeziwe ukuvimbela i-polymerization. Emphakathini, igama elithi "formalin" livame ukusetshenziswa ukubhekisela esilondolozini sezidumbu noma uketshezi olunephunga elinamandla. Ngakolunye uhlangothi, i-formalin nayo idlala indima ebalulekile emikhakheni eyahlukene yezimboni... Funda kabanzi
Indlela Yokunquma Amafomula E-Empirical kanye Nama-Molecular Ku-chemistry, ukuqonda ukwakheka kwe-compound kuyisinyathelo esiyisisekelo sokuqaphela izakhiwo zayo, ukusabela kwayo, ngisho nokulungiswa kwayo. Imiqondo emibili ebalulekile evame ukuvela ezifundweni ze-chemistry amafomula e-empirical kanye namafomula e-molecule. Nakuba womabili "amafomula" e-compound, anezincazelo ezahlukene. Ifomula ye-empirical ikhombisa isilinganiso esilula kakhulu senani lama-athomu ayingxenye,... Funda kabanzi
Ukusabela Kwamakhemikhali Kumaseli E-Electrolytic Iseli le-electrolytic liyithuluzi elisebenzisa amandla kagesi ukuphoqa ukusabela kwamakhemikhali okungavamile ukwenzeka ngokuzenzekelayo. Ngokungafani namaseli e-galvanic (amaseli e-voltaic), akhiqiza ugesi kusuka ekuphenduleni kwe-redox okuzenzakalelayo, amaseli e-electrolytic "asebenzisa" ugesi ukuguqula izinto zibe ezinye izinhlobo ngezinqubo ze-oxidation kanye nokunciphisa. Lobu buchwepheshe bubalulekile… Funda kabanzi
Ukuqonda Nokusebenza Kwama-Chemical Reactors: Ama-chemical reactor ayisisekelo sezinqubo ezahlukahlukene zezimboni, akhiqiza imikhiqizo ebalulekile empilweni yansuku zonke, kusukela kumafutha kanye nomanyolo kuya kwemithi kanye nepulasitiki kuya kuma-ejenti okuhlanza. Ngaphakathi kwe-reactor, izinto zokusetshenziswa (ama-reactants) ziguqulwa ngamakhemikhali zibe imikhiqizo ngokusebenzisa ukusabela okulawulwayo. Ngenxa yokuthi ukusabela kwamakhemikhali kungaqhubeka ngokushesha noma kancane, kukhiqiza ukushisa... Funda kabanzi
Indima Yama-Catalyst Embonini Yamakhemikhali Imboni yamakhemikhali yanamuhla ayihlukani nokuba khona kwama-catalyst. Cishe yonke imikhiqizo yamakhemikhali ebalulekile—kusukela kumafutha kanye nomanyolo kuya kumapulasitiki kanye nemithi kuya kuma-agent okuhlanza—ikhiqizwa ngokusebenzisa ukusabela kwamakhemikhali okudinga izimo ezithile ukuze kuqhubeke ngokushesha nangokusebenza kahle. Yilapho ama-catalyst edlala khona indima ebalulekile: ukusheshisa amazinga okusabela, ukwandisa ukukhetha emikhiqizweni oyifunayo, kanye… Funda kabanzi
