Feem ntau nyob rau hauv lub xeev molten, nws yog a zoo conductor ntawm hluav taws xob . Calcium chloride yog phem tus thawj coj ntawm tshav kub. Nws qhov kub hnyiab yog siab li 1935 ° C. Nws ishygroscopic nyob rau hauv cov xwm thiab absorbs noo noo los ntawm huab cua.
Kuj nug, vim li cas cov tshuaj calcium chloride ua hluav taws xob?
Calcium looses 2 electrons thiab 2 tshuaj chloride ions txais cov electrons los tsim cov ionic compound. Aquaous andmolten calcium chloride muaj mobile ions thiab qhov no yog dab tsi yog lub luag hauj lwm rau lub hluav taws xob conductivity. Qhov feem ntau ntawm cov ionic compound ua hluav taws xob thaum nyob hauv lub xeev themolten.
Ib tug kuj yuav nug, yog vim li cas sodium chloride yog ib tug zoo conductor ntawm hluav taws xob? Raws li nrog sodium chloride , ntau cov cua sov yuav tsum tau los kov yeej cov kev nyiam ntawm cov ions (vim cov lattice enthalpy siab ntawm cov compound), yog li cov ntsiab lus thermal thiab boiling kuj siab. Khoom magnesium tshuaj chloride yog tsis yog- conductor ntawm hluav taws xob vim cov ions raug txwv.
Tsis tas li ntawd, vim li cas NaCl yog cov khoom siv ntau dua li CaCl2?
Vim NaCl muaj ob ions, CaCl 2 muaj 3 ions, thiab AlCl3 muaj 4 ions, AlCl3 yuav yog feem ntau concentrated nrog lub siab tshaj plaws conductivity thiab NaCl yuav yog qhov tsawg tshaj plaws concentrated nrog qis tshaj conductivity . Vim peb tab tom soj ntsuam nrog acids thiab bases, lub feem ntau conductive molecule yuav yog HCl vim nws muaj zog acid.
Cov khoom ntawm CaCl2 yog dab tsi?
Lub cev khoom : Calcium chloride yog pom zoo li cov hmoov dawb tsis muaj ntxhiab, granules lossis flakes. Nws muaj adensity ntawm 2.15 g / mL, melting point ntawm 782 ° C thiab high boiling point tshaj 1600 ° C.

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 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
Kev sib raug zoo ntawm hluav taws xob thiab hluav taws xob teb yog dab tsi?
Electric teb yog txhais raws li lub zog hluav taws xob ib chav tsev nqi. Cov kev taw qhia ntawm lub teb yog coj mus rau qhov kev taw qhia ntawm lub zog nws yuav ua rau ib tug zoo kuaj nqi. Cov hluav taws xob hluav taws xob yog radially sab nraud los ntawm tus nqi zoo thiab radially mus rau qhov tsis zoo ntawm tus nqi
