Nyiaj yog lustrous, mos, heev ductile thiab malleable hlau. Nws muaj qhov siab tshaj plaws hluav taws xob conductivity ntawm tag nrho cov hlau, tab sis nws tsis yog dav siv rau hluav taws xob lub hom phiaj vim nws kim heev. Nyiaj tsis yog chemically active hlau; Txawm li cas los xij, nitric acid thiab kub concentrated sulfuric acid yuav ua rau nws.
Ntxiv rau qhov no, puas yog hluav taws xob ua khoom siv tshuaj?
Ib lub cev vaj tse ntawm cov khoom ntshiab yog txhua yam uas peb tuaj yeem soj ntsuam yam tsis hloov nws tus kheej. Hluav taws xob conductivity yog lub cev vaj tse . Ib txoj hlua tooj liab tseem yog tooj liab thaum nws yog ua hluav taws xob.
Tsis tas li ntawd, pH puas yog tshuaj lom neeg lossis lub cev? A chemical khoom yog ib tug yam ntxwv uas tsuas yog ntsuas los ntawm kev hloov ib yam khoom tshuaj tus kheej. A chemical khoom tsis tuaj yeem tsim los ntawm kev kov lossis saib cov khoom. Yuav tsum muaj ib tshuaj hloov mus pom nws! Qee qhov piv txwv yog: flammability, pH , thiab reactivity nrog dej los yog acid.
Tsis tas li ntawd, puas yog refractive index yog cov cuab yeej tshuaj?
Ib qho hnyav vaj tse yog bulk vaj tse , txhais tau hais tias nws yog lub cev vaj tse ntawm qhov system uas tsis nyob ntawm qhov system loj lossis cov khoom siv hauv qhov system. Piv txwv ntawm intensive khoom suav nrog kub, Refractive Index , ntom, thiab hardness ntawm ib yam khoom.
Puas yog Silver muaj cov khoom siv tshuaj lom neeg?
Ntshiab nyiaj yog ze li ntawm dawb, lustrous, mos, ductile heev, malleable, nws yog ib zoo heev conductor ntawm tshav kub thiab hluav taws xob. Nws tsis yog tshuaj lom neeg hlau, tab sis nws raug tawm tsam los ntawm nitric acid (ua cov nitrate) thiab kub concentrated sulfuric acid. Nyiaj yog ruaj khov nyob rau hauv dej.

Dab tsi yog cov yam ntxwv ua siab hloov hluav taws xob hloov hluav taws xob LET muaj thaum piv nrog LET hluav taws xob tsawg?
Dab tsi yog cov yam ntxwv ua kom muaj hluav taws xob hloov hluav taws xob siab (LET) hluav taws xob muaj thaum piv nrog cov hluav taws xob qis-LET? Cov huab hwm coj ntau ntxiv, txo qhov nkag mus. (Vim lawv cov nqi hluav taws xob thiab cov khoom loj heev, lawv ua rau ntau ionizations hauv cov ntaub so ntswg, sai sai poob lub zog
Cov cuab yeej hluav taws xob siv hluav taws xob ntau npaum li cas?
Tsis tas li ntawd, nco ntsoov txhua yam cuab yeej uas tuaj yeem xaim los khiav ntawm 240 volts es tsis yog tus qauv 120. Tus qauv amperage rau cov cuab yeej hluav taws xob me (sander, jigsaw, thiab lwm yam) yog 2 txog 8 amps. Rau cov cuab yeej hluav taws xob loj (router, ncig pom, tablesaw, tshuab dhos thiab lwm yam), 6 txog 16 amps yog qhov raug
Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms?
Tus nqi zoo attracts tus nqi tsis zoo thiab ua rau lwm tus nqi zoo. Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms? Cov nqi hluav taws xob yog cov cuab yeej ntawm tag nrho cov atoms
Dab tsi yog kauj ruam transformers siv hauv kev xa hluav taws xob hluav taws xob?
Cov hluav taws xob hluav taws xob tau xa mus rau qhov ntev ntawm qhov hluav taws xob siab. Yog li, cov kauj ruam nce transformers yog siv ntawm cov chaw nres tsheb fais fab kom nce qhov hluav taws xob ntawm lub zog whereas cov kauj ruam-down transformers yog siv los txo qhov voltage mus txog 220 V
Dab tsi yog qhov zoo ntawm kev siv lub tshuab hluav taws xob hloov hluav taws xob hauv atomic absorption?
Qhia qhov zoo thiab qhov tsis zoo ntawm lub cub tawg piv nrog kev siv cov nplaim taws hauv atomic absorption spectroscopy. Cov txiaj ntsig tseem ceeb yog ntau dua rhiab heev (concentration thiab tshwj xeeb tshaj yog loj). Lub ntsiab tsis zoo yog cov cuab yeej cuab tam ntau dua thiab cov nqi ntsuas
