Ib dej daws yog ib qho tshuaj nyob rau hauv uas cov kuab tshuaj yog dej. Nws yog feem ntau qhia hauv tshuaj equations los ntawm appending (aq) rau qhov cuam tshuam tshuaj qauv. Ib qho piv txwv ntawm cov tshuaj hydrophilic yog sodium chloride. Acids thiab bases muaj dej kev daws teeb meem, raws li ib feem ntawm lawv cov ntsiab lus Arrhenius.
Yog li ntawd, lo lus aqueous sawv cev li cas?
Aqueous txhais Cov lus aqueous kuj tau siv los piav txog kev daws teeb meem lossis sib tov hauv cov dej twg yog cov kuab tshuaj. Thaum achemical hom muaj tau yaj hauv dej, qhov no yog denoted los ntawm kev sau ntawv (aq) tom qab lub npe tshuaj.
Tsis tas li ntawd, qhov sib txawv ntawm cov kua thiab aqueous yog dab tsi? Qhov tseem ceeb thiab yooj yim qhov sib txawv ntawm ib dej daws thiab kua yog a ua kua yog ib lub xeev ntawm cov teeb meem uas muaj ib co zoo yam ntxwv uas distinguishes nws los ntawm lwm lub xeev ntawm teeb meem, piv txwv li, solids andgases; hos ib dej kev daws yog ib qho kev daws qhov twg thesolvent yog dej, uas yog a ua kua , thiab ib co
Hauv qhov no, cov piv txwv ntawm cov tshuaj aqueous yog dab tsi?
Aqueous Solution Piv txwv Cola, ntsev, nag, kua qaub kev daws teeb meem , base kev daws teeb meem , thiab ntsev kev daws teeb meem yog piv txwv ntawm cov kev daws teeb meem . Piv txwv ntawm kev daws teeb meem uas tsis yog aqueous daws suav nrog cov kua uas tsis muaj dej.
Cov dej puas muaj dej?
H2O ( dej ) muaj nyob rau hauv peb theem sib txawv hauv qhov - khoom (ice), kua ( dej ), thiab gas ( dej vapor los yog vapor). Txhua yam khoom uas tau muab tso rau hauv dej hais tias nyob rau hauv ib qho dej xeev (nco ntsoov tias aqua txhais tau tias dej ). Yog li, rau dej bein ib dej lub xeev yog nyob rau hauv nws tus kheej, acontradiction.

Qhov feem pua txhais li cas hauv chemistry?
Cov feem pua ntau yog ib txoj hauv kev los sawv cev qhov concentration ntawm cov khoom hauv ib qho kev sib xyaw lossis cov khoom sib xyaw hauv cov khoom sib xyaw. Cov feem pua ntau yog xam raws li qhov loj ntawm ib feem faib los ntawm tag nrho cov loj ntawm qhov sib tov, muab 100%
Qhov ntau txhais li cas hauv chemistry?
'Bulk' txhais tau hais tias cov cuab yeej ntawm ib yam khoom uas muaj qhov loj thiab qhov no yog tib lub ntsiab lus uas yog siv rau hauv qhov chaw chemistry rau cov khoom siv-gas, khoom-kua, kua-gas thiab kua-kua, raws li lawv (khoom orliquid lossis gas) yog siv nyob rau hauv loj npaum li cas (piv txwv li nyob rau hauv tej) totudy txog cov sib txawv theem
Kev taw qhia txhais li cas hauv chemistry?
Kev taw qhia hauv chemistry txhais tau hais tias thaum lub sijhawm tshuaj tiv thaiv kev sib tsoo ntawm cov atoms. Cov reactant molecules yuav tsum sib tsoo nrog kev pom zoo. Txoj kev taw qhia tseeb yog qhov uas ua kom muaj kev sib cuag ncaj qha ntawm lub atom koom nrog hauv kev sib tsoo thiab kev sib koom ua ke
Lub thickness txhais li cas hauv chemistry?
Txhais ntawm thickness. 1: ntawm txheej epitaxial, qhov kev ncua deb ntawm qhov chaw ntawm lub wafer mus rau txheej-substrate interface. [
Dab tsi yog qhov sib npaug ionic rau cov tshuaj tiv thaiv ntawm aqueous lead II nitrate nrog aqueous sodium bromide?
Cov tshuaj tiv thaiv ntawm aqueous sodium bromide thiab aqueous lead (II) nitrate yog sawv cev los ntawm qhov sib npaug net ionic equation. 2Br−(aq)+Pb2+(aq) →PbBr2(s) 2 B r − (a q) + P b 2 + (a q) → P b B r 2 (s)
