Ukuthuthukiswa kwamakhemikhali angokwemvelo kuyindaba ende ehlanganiswe nelukuluku, inhlanhla, kanye nokuphishekela isayensi okungapheli. … Funda kabanzi

Indlela Yokwenza Izixazululo Ze-Buffer: Umhlahlandlela Ophelele Izixazululo ze-buffer zidlala indima ebalulekile ekugcineni ibhalansi ye-pH yezinqubo ezahlukahlukene zebhayoloji, zamakhemikhali, nezezimboni. Ziyingxenye ebalulekile ekuhlolweni kwekhemistri kanye nebhayoloji, okuqinisekisa ukuthi i-pH ihlala ingaguquki naphezu kwama-asidi noma izisekelo ezengeziwe. Lesi sihloko sizohlinzeka ngomhlahlandlela ophelele wokuthi kanjani … Funda kabanzi

Ukusetshenziswa kwe-UV-Vis Spectrophotometer Isingeniso I-Ultraviolet-Visible (UV-Vis) spectrophotometry iyindlela yokuhlaziya eguquguqukayo esetshenziswa kabanzi ocwaningweni lwesayensi, izinhlelo zokusebenza zezimboni, kanye nokuhambisana nemithetho. Le ndlela isebenzisa ukumuncwa kokukhanya ezindaweni ze-ultraviolet (UV) kanye nezibonakalayo (Vis) ze-electromagnetic spectrum ngama-molecule nama-ion ukuze kunikezwe ulwazi oluningi nolusezingeni mayelana nesampula. … Funda kabanzi

Ukusabela Kwamakhemikhali Ku-Photosynthesis: Ukusebenzisa Ukukhanya Ukuze Kuphembelele Ukuphila I-Photosynthesis kungenzeka ukuthi ingenye yezinqubo zamakhemikhali ezibaluleke kakhulu zokuphila eMhlabeni. Ngochungechunge oluyinkimbinkimbi lokusabela, izitshalo, ulwelwe, namabhaktheriya athile aguqula amandla okukhanya abe amandla amakhemikhali, ondla cishe zonke izinhlobo zokuphila ngokuqondile noma ngokungaqondile. Lesi sihloko sigxila kumakhemikhali … Funda kabanzi

Kuyini Ukusabela Kwemvula? Isingeniso I-Chemistry, isifundo sezinto kanye nokusebenzisana kwazo, ihlanganisa izinhlobo eziningi zezehlakalo kanye nokusabela. Phakathi kwalezi zindlela zokusabela, ukusabela kwemvula kunendawo ebalulekile ngenxa yezicelo zazo ezisebenzayo kanye nokubaluleka okuyisisekelo ekuqondeni ukusebenzisana kwamakhemikhali. Ukusabela kwemvula kuyinqubo lapho izinto ezimbili ezincibilikayo zisabela khona … Funda kabanzi

Izakhiwo Zomzimba Nezamakhemikhali Zamagesi Ahloniphekile Amagesi ahloniphekile – i-helium (He), i-neon (Ne), i-argon (Ar), i-krypton (Kr), i-xenon (Xe), ne-radon (Rn) – ahlala eqenjini le-18 lethebula le-periodic. Lezi zinto ziphawuleka ngokuqina kwazo okumangalisayo kanye nokuntuleka kokusabela ngaphansi kwezimo ezijwayelekile. Lokhu kuziphatha okuyingqayizivele kungenxa ye-valence yazo ephelele … Funda kabanzi

Ukuqonda Ukumuncwa Nokusetshenziswa Kwako Ukumuncwa kuyinqubo ebalulekile yesayensi ehlanganisa izimboni nezinhlelo zokusebenza ezahlukahlukene. Kusukela ekuphathweni kwamanzi nasekulawulweni kokungcola kuya ekugcinweni kwegesi kanye nemithi, ukufinyelela kwayo kubanzi. Ukuqonda ukumuncwa kuhilela ukucwaninga ngezimiso, izinhlobo, kanye nezinhlelo zokusebenza zangempela. Kuyini Ukumuncwa? Ukumuncwa kuyinqubo lapho ama-molecule noma izinhlayiya zinamathela khona … Funda kabanzi

Indlela Yokunquma Ukuhleleka Kokusabela: Umhlahlandlela Ophelele I-kinetics yamakhemikhali, igatsha le-chemistry yemvelo, ihlola ngokucophelela amazinga okusabela kwamakhemikhali kanye nezici ezithinta wona. Okubalulekile kulolu cwaningo umqondo wokuhleleka kokusabela, okubalulekile ekuqondeni ubudlelwano phakathi kokuhlushwa kwe-reactant kanye nesilinganiso sokusabela. Ukunquma ukuhleleka kokusabela kunikeza ukuqonda … Funda kabanzi

Isihloko: Amasu e-Electrophoresis ku-Biochemistry Isingeniso I-Electrophoresis iyindlela eyisisekelo ku-biochemistry kanye ne-molecular biology, ebaluleke kakhulu ekuhlaziyweni nasekuhlukanisweni kwama-macromolecule, njenge-nucleic acid kanye namaprotheni. Le ndlela isebenzisa ukufuduka okuhlukile kwezinhlayiya ezishajiwe ngaphansi kwensimu kagesi, okuvumela ososayensi ukuthi bahlukanise izingxube eziyinkimbinkimbi zibe izingxenye zazo ngazinye. I-Electrophoresis … Funda kabanzi

Isihloko: Iyini Isixazululo se-Hypotonic? Emkhakheni wekhemistri kanye ne-biology, igama elithi “isixazululo se-hypotonic” libaluleke kakhulu, ikakhulukazi lapho kuxoxwa nge-physiology yeseli kanye nezinqubo ze-osmotic. Ukuqonda ukuthi iyini ikhambi le-hypotonic nokuthi lisebenzisana kanjani namaseli kubalulekile ekuqondeni imiqondo eyisisekelo yezinto eziphilayo kanye nezimo. Lesi sihloko sigxila ku… Funda kabanzi
