Lesi sinyathelo sibalulekile… Funda kabanzi
Amasu e-Electrophoresis ku-Biochemistry I-Electrophoresis iyindlela yokuhlaziya enethonya elikhulu ku-biochemistry futhi idlale indima ebalulekile ezifundweni zesayensi ezahlukahlukene. Isebenzisa izimiso eziyisisekelo zokunyakaza kwama-molecule ensimini kagesi, i-electrophoresis ivumela ukuhlukaniswa, ukuhlonza, kanye nokuhlaziywa kwezinhlobo ezahlukene zama-biomolecule, kufaka phakathi amaprotheni, ama-nucleic acid, nama-carbohydrate. Lesi sihloko sizoxoxa ngezimiso eziyisisekelo ze-electrophoresis, … Funda kabanzi
Iyini Isixazululo se-Hypotonic? Ezweni lesayensi, ikakhulukazi ku-biology kanye ne-chemistry, igama elithi "isixazululo se-hypotonic" livame ukusetshenziswa. Kodwa-ke, siyini ngempela isisombululo se-hypotonic? Kulesi sihloko, sizohlola incazelo, izici, kanye nokusetshenziswa okusebenzayo kwezixazululo ze-hypotonic emikhakheni eyahlukene yesayensi. Ukuqonda Izixazululo ze-Hypotonic: Empeleni, ikhambi le-hypotonic liyikhambi… Funda kabanzi
Umsebenzi Wesithako Sokuhlanza Njenge-Emulsifier Isithako Sokuhlanza siyindlela yokuhlanza esiyisebenzisayo ekuphileni kwethu kwansuku zonke, kungaba ukuhlanza izingubo, ukuhlanza izitsha zokudla, noma ukunakekela ezinye izinto zasekhaya. Kodwa-ke, bewazi ukuthi omunye wemisebenzi yawo eyinhloko iwukuba yi-emulsifier? Kulesi sihloko, sizoxoxa ngokujulile ngendima kanye nendlela yokuhlanzwa njengesithako sokuhlanza njenge-emulsifier...

Umqondo we-Acid kanye ne-Base Hydrolysis I-Hydrolysis ingenye yezindlela eziningi ezibalulekile zamakhemikhali ezenzeka ezindaweni zasemanzini, idlala indima ebalulekile ezinqubweni ezahlukahlukene ze-biochemical, zezimboni, kanye nezendawo ezungezile. Ngokwesimo sama-acid kanye nezisekelo, i-hydrolysis ibhekisela ekusabeleni lapho ama-ion avela ku-asidi noma isisekelo ehlangana khona namanzi, okuholela ekushintsheni kwe-pH yesisombululo. Lesi sihloko… Funda kabanzi
Ukusetshenziswa Kwamakhemikhali Angaphili Amakhemikhali angaphili ayizinto zamakhemikhali ezingenawo amaketanga e-carbon-hydrogen ajwayelekile amakhemikhali e-organic. Ahlanganisa izigaba eziningi, okuhlanganisa amaminerali, izinsimbi, nosawoti. Amakhemikhali angaphili abelokhu esetshenziswa ezicini ezahlukene zokuphila kwabantu kusukela ezikhathini zasendulo, kusukela ezidingweni zansuku zonke kuya ekusetshenzisweni kwesayensi nobuchwepheshe obuthuthukisiwe.

Indima Yekhemistri Emvelweni Isingeniso Ikhemistri iyigatsha lesayensi elifunda izakhi, ama-compounds, izakhiwo, izakhiwo, kanye nezinguquko ezenzeka endabeni. Nakuba ngokuvamile kubhekwa njengokuyinkimbinkimbi futhi kunzima ukuyiqonda, ikhemistri idlala indima ebaluleke kakhulu empilweni yansuku zonke, ikakhulukazi esimweni semvelo. Ukuqonda okuyisisekelo kanye nokusetshenziswa kwekhemistri kungaba yisihluthulelo sokuxazulula izinkinga ezahlukahlukene zemvelo... Funda kabanzi
Ukuqonda i-Electrolysis kanye nezibonelo I-Electrolysis inqubo yamakhemikhali esebenzisa ugesi oqondile (DC) ukushayela ukusabela kwamakhemikhali okungahleliwe. Igama elithi "electrolysis" livela kumagama esiGreki athi "electro," okusho ugesi, kanye nelithi "lysis," okusho ukuhlukaniswa. Ngamanye amazwi, i-electrolysis inqubo yokuhlukanisa i-chemical compound ibe yizakhi zayo kusetshenziswa ugesi. … Funda kabanzi
Indlela Yokuhlukanisa Izingxube Ingxube iyinhlanganisela yezinto ezimbili noma ngaphezulu ezingahlanganiswanga ngamakhemikhali. Izingxube zingaba nezinto eziqinile, uketshezi, amagesi, noma inhlanganisela yazo ezintathu. Inqubo yokuhlukanisa izingxube ibalulekile emikhakheni ehlukahlukene, okuhlanganisa i-chemistry, imithi, amakhemikhali kaphethroli, kanye nokucubungula ukudla.
