Cov ntsiab lus ntawm cov tshuaj tuaj yeem qhia ntau ntau yam xws li molarity, mole fraction, thiab lwm yam. ntawm kev daws. Chav tsev ntawm molarity yog molar(M) los yog moles/L.
Peb txoj hauv kev uas qhov kev daws teeb meem tuaj yeem qhia tau yog dab tsi?
Chemists tuaj yeem nthuav qhia ntau yam hauv ntau txoj hauv kev suav nrog: Molarity (M), Qhov ib lab (ppm), % muaj pes tsawg leeg, lossis gram / Liter (g / L).
Yuav ua li cas yog qhov concentration ntawm cov tshuaj qhia hauv hoob 9?
Cov tshuaj uas muaj cov kuab tshuaj ntau yog hu ua Concentrated Solution. Qhov concentration ntawm cov tshuaj yog txhais raws li hnyav ntawm cov kua hauv grams tam sim no hauv 100 g ntawm cov tshuaj. … Saturated tov muaj ntau npaum li cas ntawm solute uas yuav yaj nyob rau hauv nws ntawm ib tug muab kub.
Vim li cas peb thiaj li yuav tsum tau nthuav tawm cov ntsiab lus ntawm kev daws teeb meem ntau?
Cov ntsiab lus concentrated thiab dilute tsuas yog cov lus txheeb ze. Ib qho tshuaj muaj zog muaj ntau dua nyob hauv nws dua li cov tshuaj dilute; Txawm li cas los xij, qhov no tsis qhia txog qhov tseeb npaum li cas ntawm solute tam sim no. Yog li ntawd, peb xav tau ntau qhov tseeb, ntau txoj hauv kev ntawm kev nthuav qhia concentration.
Chav tsev twg siv tau los qhia txog qhov kev daws teeb meem?
Txoj kev xav(M) qhia txog tus naj npawb ntawm moles ntawm cov kuab tshuaj ib liter ntawm kev daws (moles / Liter) thiab yog ib qho ntawm feem ntau units siv los ntsuas qhov concentration ntawm cov tshuaj. Molarity yuav siv tau los xam qhov ntim ntawm cov kuab tshuaj los yog tus nqi ntawm solute.

Qhov twg yog qhov kev txiav txim siab rau kev tsis lees paub thiab rau kev ua kom muaj kev tawm tsam ntawm kev tawm tsam?
Kev qhuab ntuas tau siv los ntawm cov thawj coj loj hauv cov tub rog Romanrau txim rau cov koom haum lossis pab pawg loj ua txhaum cai, xws li kev ua phem, kev tawm tsam, kev tawm tsam, thiab kev tsis ncaj ncees, thiab rau lub pacification ntawm rebellious legions.
Txhua qhov kev sib npaug plaub npaug tuaj yeem daws tau los ntawm kev tsim?
Tsis yog txhua qhov kev sib npaug plaub npaug tuaj yeem ua tiavlossis tuaj yeem daws tau hauv lawv daim ntawv qub uas siv cov cuab yeej square. Hauv cov xwm txheej no, peb tuaj yeem siv lwm txoj hauv kev los daws qhov sib npaug plaub npaug. Puas yog txhua qhov kev sib npaug plaub npaug tuaj yeem daws tau los ntawm cov qauv quadratic?
Cov ntaub ntawv ntau npaum li cas yog qhia los ntawm kev sib npaug tshuaj?
Cov ntaub ntawv ntau npaum li cas yog qhia los ntawm kev sib npaug tshuaj? Cov coefficients ntawm cov tshuaj tiv thaiv tshuaj qhia cov txheeb ze ntawm cov tshuaj reactants thiab cov khoom, cov txheeb ze ntawm cov reactants thiab cov khoom ntawm cov tshuaj tiv thaiv tuaj yeem txiav txim siab los ntawm cov tshuaj tiv thaiv coefficients, thiab rov qab rau cov tshuaj.
Qhov kev tshwm sim hauv lub neej tseem ceeb ntawm kev ntsuas kev ntsuas kev sib raug zoo twg muaj tus lej ntau tshaj?
Qhov kev tshwm sim ntawm qib siab tshaj yog tuag ntawm tus txij nkawm(nrog tus nqi nruab nrab ntawm 100), txheeb ze rau kev sib yuav, nrog tus nqi nruab nrab ntawm 50, thiab, piv txwv, kev tuag ntawm tus phooj ywg ze, uas tau qhab nia 37. Qhov xwm txheej tseem ceeb ntawm lub neej ntawm Kev Hloov Kho Kev Ntsuas Kev Ntsuas Qhov Ntsuas puas muaj cov lej hloov pauv lub neej ntau tshaj?
