Ithiyori KaLewis Ene-Acid-Base: Ukuqonda Okubanzi Nokuvamile Isingeniso U-Isaac Newton wake wathi wayekwazi ukubona okungaphezulu ngoba wayemi emahlombe eziqhwaga, futhi kumakhemikhali, izimiso eziningi eziyisisekelo esizamukelayo namuhla zimi nasemsebenzini onzima wososayensi bangaphambili. Intuthuko eyodwa ebalulekile … Funda kabanzi
Umsebenzi Wezixazululo Ze-Buffer Empilweni Isingeniso Izixazululo ze-buffer, ezaziwa nangokuthi izixazululo ze-buffering, ziyizixazululo ezigcina i-pH engaguquki ngisho noma kufakwe i-asidi noma isisekelo. Lesi simo sibalulekile ezinqubweni eziningi zebhayoloji, zamakhemikhali, kanye nezezimboni. Empilweni yansuku zonke, imisebenzi yezixazululo ze-buffer ibalulekile futhi iyahlukahluka, kusukela ekusekeleni... Funda kabanzi
# Izinhlobo Zokusabela Kwamakhemikhali Nezibonelo I-Chemistry iyigatsha lesayensi elifunda ukwakheka, isakhiwo, izakhiwo, kanye nezinguquko zezinto. Isici esibalulekile se-chemistry ukusabela kwamakhemikhali. Ukusabela kwamakhemikhali inqubo lapho into eyodwa noma ngaphezulu (ama-reactant) iguqulwa ibe yinto eyodwa noma ngaphezulu (imikhiqizo). Kulesi sihloko, sizoxoxa ngezinhlobonhlobo... Funda kabanzi
### Umlando Wokuthuthukiswa Kwethiyori Ye-Athomu #### Isingeniso Ithiyori ye-athomu ingenye yezinsika ezibalulekile zekhemistri nefiziksi, esisiza siqonde isakhiwo kanye nezakhiwo zezinto. Umlando wokuthuthukiswa kwethiyori ye-athomu ubonisa uhambo olude lwesayensi, kusukela ekuqageleni kwefilosofi yasendulo kuya ekuhlolweni kwesayensi yesimanje. Lesi sihloko sizochaza ukuthuthukiswa komqondo we-athomu kusukela esikhathini samaGreki… Funda kabanzi
# Indlela Yokubala Ama-Moles kuKhemistri I-mole iyiyunithi eyisisekelo kukhemistri esetshenziselwa ukuveza inani elikhulu kakhulu lezinhlayiya, njenge-athomu, ama-molecule, noma ama-ion. I-mole eyodwa ilingana nezinhlayiya ze-\(6,022 \times 10^{23}\), inombolo eyaziwa ngokuthi i-Avogadro's Constant. Ukuqonda kanye nekhono lokubala ama-moles kubalulekile ezinhlobonhlobo zezicelo zamakhemikhali, kusukela ekwakheni izibalo zamakhemikhali kuya... Funda kabanzi
Iyini Ithebula Lezinto Eziphilayo KuKhemistri? Ithebula lezinto eziphilayo lingenye yamathuluzi abaluleke kakhulu kukhemistri, linikeza umbono ohlelekile wezakhi ezakha yonke into endaweni yonke. Eyethulwa okokuqala nguDmitri Mendeleev ngo-1869, isibe yindawo okufanele ibe nayo yososayensi, abafundisi, kanye nabafundi emhlabeni jikelele. Ku… Funda kabanzi
