Kodi Lamulo la Raoult mu Chemistry Ndi Chiyani? Mu chemistry, makamaka pophunzira mayankho ndi mawonekedwe a zosakaniza, pali lingaliro lofunika lomwe nthawi zambiri limagwiritsidwa ntchito pofotokoza momwe mphamvu ya nthunzi ya chinthu imasinthira ikasakanizidwa ndi chinthu china. Lingaliroli limadziwika kuti Lamulo la Raoult. Lamuloli ndi lofunikira pakumvetsetsa zochitika zosiyanasiyana za tsiku ndi tsiku ndi njira zamafakitale,... Werengani zambiri

Kumvetsetsa Zotsatira za Nyukiliya ndi Zitsanzo Zotsatira za nyukiliya ndi chimodzi mwa zinthu zofunika kwambiri mu sayansi ya masiku ano chifukwa zimakhudza kusintha komwe kumachitika mu nyukiliya. Mosiyana ndi zotsatira za mankhwala, zomwe zimaphatikizapo kusamutsa kapena kuphatikiza ma elekitironi mkati mwa chipolopolo cha atomu, zotsatira za nyukiliya zimachitika mwachindunji mu nyukiliya ya atomu, yomwe imapangidwa ndi ma proton ndi ma neutron. Zotsatira zake, zotsatira za nyukiliya zimatha... Werengani zambiri

Njira Zogwiritsira Ntchito Chromatography Yopyapyala mu Mankhwala Chiyambi Chromatography Yopyapyala (TLC) ndi njira yodziwika bwino yowunikira yomwe imagwiritsidwa ntchito m'munda wa mankhwala. Njirayi imadziwika chifukwa cha kuphweka kwake, liwiro lake, komanso mtengo wake, komanso kuthekera kwake kupereka chidziwitso chofunikira chokhudza kapangidwe ka chitsanzo. Mu ma laboratories a mankhwala, TLC imagwiritsidwa ntchito nthawi zambiri pazinthu zonse kuyambira... Werengani zambiri

Ntchito ya Ma carbohydrate mu Thupi Ma carbohydrate ndi ma organic omwe ndi ofunikira pa moyo wa munthu. Mu zakudya, ma carbohydrate amaphatikizidwa mu gulu la macronutrients, pamodzi ndi mapuloteni ndi mafuta, chifukwa amafunikira kwambiri kuti athandizire ntchito za thupi. Ma carbohydrate nthawi zambiri amagwirizanitsidwa ndi "magwero a mphamvu," koma ntchito yawo kwenikweni ndi yochulukirapo... Werengani zambiri

Kugwiritsa Ntchito Ma Centrifuge mu Ma Laboratories Ma Centrifuge ndi zida zofunika kwambiri m'ma laboratories osiyanasiyana, kuyambira ma labotale azachipatala, ma labotale a biology, ndi ma labotale a chemistry mpaka mafakitale azamankhwala ndi chakudya. Amagwira ntchito motsatira mfundo ya mphamvu ya centrifugal, mphamvu yopangidwa ndi kuzungulira mwachangu komwe kumalekanitsa tinthu tating'onoting'ono mu chitsanzo kutengera kusiyana kwa kuchuluka ndi kukula. … Werengani zambiri

Ubwino ndi Kuopsa kwa Ma Formalin Compounds Formalin ndi yankho lomwe lili ndi formaldehyde m'madzi, nthawi zambiri limakhala ndi 37% formaldehyde, nthawi zambiri limaphatikizidwa ndi methanol yochepa kuti lipewe kusungunuka kwa polymer. M'gulu la anthu, mawu oti "formalin" nthawi zambiri amagwiritsidwa ntchito kutanthauza chosungira cha mitembo kapena madzi onunkhira bwino. Kumbali ina, formalin imagwiranso ntchito yofunika kwambiri m'magawo osiyanasiyana amafakitale... Werengani zambiri

Momwe Mungadziwire Mafomula Olimbitsa Thupi ndi Ma Molekyu Mu chemistry, kumvetsetsa kapangidwe ka chinthu ndi gawo lofunikira kwambiri pozindikira mawonekedwe ake, reactivity, komanso kukonzekera kwake. Malingaliro awiri ofunikira omwe amapezeka nthawi zambiri m'maphunziro a chemistry ndi ma fomula olimbitsa thupi ndi ma fomula a ma molekyulu. Ngakhale onsewa ndi "ma fomula" a chinthu, ali ndi matanthauzo osiyanasiyana. Fomula yolimbitsa thupi imasonyeza chiŵerengero chosavuta cha chiwerengero cha ma atomu omwe ali m'gulu,...
