Mineral roj yog siv kho cem quav. Nws yog lub npe hu ua lubricant laxative. Nws ua haujlwm los ntawm kev khaws dej hauv cov quav thiab cov hnyuv. Qhov no yuav pab ua kom cov quav mos thiab tseem ua rau nws yooj yim dua rau cov quav mus rau hauv cov hnyuv.
Ntxiv mus, Nujol yog dab tsi hauv chemistry?
Kev txhais ntawm Nujol . Cov roj av kub npau npau feem ntau siv los ua cov kuab tshuaj rau IR spectroscopy vim nws tsis muaj IR absorption bands.
Tsis tas li ntawd, dab tsi Wavenumbers ua Nujol nqus? Infrared Spectroscopy (IR) Nws nqus ntawm wavelength li ntawm 3800 cm - 1 c m - 1 mus rau 400 cm - 1 c m - 1. Nws muaj ob thaj tsam xws li thaj tsam ua haujlwm pab pawg thiab cheeb tsam ntiv tes. Wavelength thiab tus lej wavenum yog inversely proportional rau ib leeg.
Tom qab ntawd, ib tus tuaj yeem nug, vim li cas Nujol siv hauv IR?
Rau cov qauv reactive heev, txheej ntawm Nujol tuaj yeem muab cov txheej txheem tiv thaiv, tiv thaiv cov qauv decomposition thaum tau txais cov IR spectrum.
Nujol yog dab tsi Nujol mull yog dab tsi?
A nuj mol yog tau los ntawm kev sib tsoo cov khoom thiab sib tov nrog cov ntxhia roj los ua ib qho kev ncua, uas muab tso rau hauv nruab nrab ntawm AgCl, NaCl, KBr lossis CsI daim hlau. (Nco ntsoov: Tau txais spectrum ntawm cov roj ntxhia ib yam nkaus). Lub compound yuav tsum tau zoo dispensed ntawm daim hlau kom tau ib tug zoo spectrum.

Dab tsi ntawm pipette yog volumetric thiab nws siv rau dab tsi?
Lub volumetric pipette, noob pipette, lossis lub plab pipette tso cai rau kev ntsuas qhov tseeb (rau plaub qhov tseem ceeb) ntawm qhov ntim ntawm cov tshuaj. Volumetric pipettes feem ntau yog siv rau hauv analytical chemistry los ua cov kev daws teeb meem los ntawm lub hauv paus Tshuag thiab npaj cov kev daws teeb meem rau titration
Dab tsi yog kev siv cov saw hlau nuclear siv rau?
Nuclear chain reaction. Nuclear chain reactions yog cov tshuaj tiv thaiv uas tau txais lub zog nuclear, feem ntau los ntawm nuclear fission. Cov kev cuam tshuam ntawm cov saw hlau no yog qhov muab cov chaw tsim hluav taws xob nuclear nrog lub zog uas tom qab ntawd hloov mus ua hluav taws xob siv los ntawm tib neeg
Dab tsi yog qhov sib npaug siv los xam tag nrho cov khoom siv hluav taws xob siv?
Cov mis uas txuas lub zog thiab lub zog yog: Zog = Lub Zog x Sijhawm. Chav tsev ntawm lub zog yog joule, lub zog ntawm lub zog yog watt, thiab chav tsev ntawm lub sijhawm yog qhov thib ob
Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
Dab tsi yog qhov txawv ntawm cov khoom siv organic thiab cov khoom siv organic?
Dab tsi yog qhov txawv ntawm cov khoom siv organic thiab organic teeb meem? Organic khoom yog txhua yam uas tseem muaj sia nyob thiab tam sim no nyob rau hauv lossis hauv av. Rau nws los ua cov organic teeb meem, nws yuav tsum tau decomposed rau hauv humus. Humus yog cov khoom siv organic uas tau hloov dua siab tshiab los ntawm cov kab mob mus rau lub xeev tsis muaj zog
