Ua kom pom qhov no, vim li cas AlCl3 tsis yog txhuas trichloride?
Txawm li cas los xij, aluminium chloride , AlCl3 , yog qee zaum hu ua aluminium trichloride uas yog tsis yog Tsis yog nyob rau hauv cov ntaub ntawv no vim hais tias nws yeej yog ib tug molecular compound (nws muaj polar heev aluminium -chlorine covalent bonds) txawm tias nws zoo li nws yuav tsum yog ionic vim nws muaj cov hlau thiab cov hlau tsis muaj hlau uas raug ionic.
Dab tsi yog qhov molar loj rau aluminium chloride?
133.34 g / mol

Dab tsi yog qhov feem pua enantiomeric tshaj ntawm qhov sib tov uas muaj 86?
Enantiomeric tshaj (ee): Qhov ntau tshaj ntawm ib qho enantiomer tshaj qhov sib tov ntawm enantiomers. Qhia lej: enantiomeric tshaj = % ntawm cov enantiomer loj - % ntawm cov me me enantiomer. Piv txwv li: Ib qho kev sib xyaw ua ke ntawm 86% R enantiomer thiab 14% S enantiomer muaj 86% - 14% = 72% ee
