Isingeniso Amakhemikhali e-organic ahlukene kakhulu futhi anezindlela eziningi zokusetshenziswa emikhakheni eyahlukene. Amakilasi amabili abalulekile amakhemikhali e-organic yi-aldehydes nama-ketone. Womabili angama-carbonyl derivatives, okusho ukuthi aqukethe iqembu elisebenzayo le-carbonyl (C=O). Leli qembu lisabela kakhulu futhi lidlala indima ebalulekile ekwelashweni kwamakhemikhali ahlukahlukene. Lesi sihloko sizoxoxa ngokusetshenziswa kwama-aldehydes nama-ketones… Funda kabanzi

Ithiyori Yesisekelo Se-Bronsted-Lowry Acid: Ukuqonda Okujulile Ama-acid kanye nezisekelo kuyimibono emibili eyisisekelo kumakhemikhali edlala indima ebalulekile ekuphenduleni kwamakhemikhali ahlukahlukene kanye nezinqubo zezinto eziphilayo. Eminyakeni edlule, kuye kwaphakanyiswa imibono ehlukahlukene ukuchaza izakhiwo kanye nokuziphatha kwama-acid kanye nezisekelo. Enye yezinkolelo-mbono ezinethonya kakhulu yithiyori yesisekelo se-Bronsted-Lowry acid, eyethulwa… Funda kabanzi

Izinzuzo Zezinhlanganisela Zotshwala Utshwala luyinhlanganisela yamakhemikhali ephilayo equkethe iqembu le-hydroxyl (-OH) elihlanganiswe ne-athomu yekhabhoni. Njengoba ulwazi lwe-chemistry ephilayo luye lwathuthuka, utshwala butholakale bunezinzuzo ezahlukahlukene empilweni yomuntu, okuhlanganisa kwezokwelapha, embonini, ezimonyweni, nasempilweni yansuku zonke. Lesi sihloko sizoxoxa ngezinzuzo ezahlukahlukene zezinhlanganisela zotshwala ezicini ezahlukene zokuphila kwethu. … Funda kabanzi

Indlela Imitha ye-pH Esebenza Ngayo: Ukulinganisa i-pH kubalulekile emikhakheni eyahlukene, okuhlanganisa ikhemistri, i-biology, ubunjiniyela, kanye nezokwelapha. Ithuluzi elisetshenziswa ukukala i-pH yesisombululo libizwa ngokuthi imitha ye-pH. Lesi sihloko sizochaza ngokujulile isimiso sokusebenza semitha ye-pH, izingxenye zayo, kanye nokusetshenziswa kwayo emikhakheni eyahlukene. Isingeniso: I-pH iyisilinganiso se-logarithmic esisetshenziswa… Funda kabanzi

Umlando Wokuthuthukiswa Kwe-Organic Chemistry Isingeniso I-organic chemistry iyigatsha le-chemistry elifunda ama-carbon compounds kanye nokusabela kwawo. Nakuba kungase kuzwakale kuncane, leli gatsha empeleni libanzi kakhulu, lihlanganisa konke kusukela kuma-biomolecules ezintweni eziphilayo kuya ezintweni zokwenziwa ezifana nepulasitiki kanye nemithi. Ukuthuthukiswa kwe-organic chemistry kubonisa uhambo olude ekuqondeni komuntu izinto ezisizungezile kanye... Funda kabanzi

Indlela Yokwenza Isixazululo Se-Buffer Isingeniso Isixazululo se-buffer yisisombululo samakhemikhali esigcina i-pH engaguquki ngisho noma kufakwe inani elincane le-asidi noma isisekelo. Izixazululo ze-buffer zibalulekile emikhakheni eyahlukahlukene, kufaka phakathi i-biochemistry, ikhemisi, kanye nama-laboratory ocwaningo. Lesi sihloko sizokhuluma ngendlela yokwenza isixazululo se-buffer, kufaka phakathi ukuqonda okuyisisekelo kokuthi izixazululo ze-buffer zisebenza kanjani, izingxenye ze-buffer, nokuthi zisetshenziswa kanjani.

Ukusetshenziswa kwama-UV-Vis Spectrophotometer ekuHlaziyweni Kwamakhemikhali I-UV-Vis (Ultraviolet-Visible) spectrophotometry iyindlela yokuhlaziya elinganiselayo nekhwalithi esebenzisa izimiso zokusebenzisana phakathi kokukhanya nezinto eziku-UV (200-400 nm) kanye nama-wavelengths abonakalayo (400-800 nm). Le ndlela isibe ithuluzi elibalulekile emikhakheni eyahlukene yesayensi, okuhlanganisa ikhemistri, i-biology, ikhemisi, isayensi yezemvelo, kanye nesayensi yezinto. Izimiso Eziyisisekelo ze-UV-Vis Spectrophotometry… Funda kabanzi

Ukusabela Kwamakhemikhali Ku-Photosynthesis I-Photosynthesis ingenye yezinqubo ezibaluleke kakhulu ze-biochemical ezenzeka eMhlabeni. Ngale nqubo, izitshalo eziluhlaza nezinye izinto eziphilayo ziyakwazi ukuguqula amandla elanga abe amandla amakhemikhali angasetshenziswa ukusekela imisebenzi ehlukahlukene yokuphila. I-Photosynthesis ayibalulekile ezitshalweni ngokwazo kuphela, kodwa futhi nasekuphileni kwezinye izinto eziphilayo, okuhlanganisa… Funda kabanzi

Kuyini Ukusabela Kwemvula? Ukusabela kwemvula uhlobo lokusabela kwamakhemikhali okwenzeka njalo empilweni yansuku zonke kanye nasezinqubweni ezahlukahlukene zezimboni. Kulokhu kusabela, izixazululo ezimbili eziqukethe ama-ion ancibilikayo ziyaxubana, zikhiqize okuqinile okungancibiliki endaweni. Lokhu okuqinile kubizwa ngokuthi i-precipitate.

Izakhiwo Zomzimba Nezamakhemikhali Zamagesi Ahloniphekile Amagesi ahloniphekile ayiqembu lezinto zamakhemikhali ezitholakala kuQembu 18 lethebula lezinto eziphindaphindwayo. Amalungu aleli qembu afaka phakathi i-helium (He), i-neon (Ne), i-argon (Ar), i-krypton (Kr), i-xenon (Xe), kanye ne-radon (Rn). Lawa magesi anezakhiwo zomzimba nezekhemikhali ezihlukile, okwenza kube mnandi ukuwafunda nokusebenzisa ezinhlobonhlobo... Funda kabanzi
