Solubility qhia qhov siab tshaj plaws tus nqi ntawm ib yam khoom uas yuav ua tau yaj hauv a kuab tshuaj ntawm qhov kub thiab txias. Xws li kev daws yog hu ua saturated. Faib qhov loj ntawm lub compound los ntawm qhov loj ntawm lub kuab tshuaj thiab ces muab 100 g rau xam solubility hauv g / 100g.
Dhau li ntawm no, koj ua li cas xam cov feem pua ntawm solubility?
Faib tus solute daim duab los ntawm lub cev hnyav. Hauv qhov piv txwv, koj yuav faib 10 los ntawm 60 thiab tau txais txiaj ntsig ntawm kwv yees li 0.167. Muab cov txiaj ntsig los ntawm Kauj Ruam 3 los ntawm 100 los txiav txim qhov solubility feem pua . Hauv qhov piv txwv, koj yuav muab 0.167 los ntawm 100 thiab tau 16.7.
Tsis tas li ntawd, koj ua li cas xam cov khoom solubility? xam tus solubility khoom . Qhov sib npaug yog: Rau txhua mole ntawm magnesium hydroxide uas yaj, koj yuav tau txais ib lub mole ntawm magnesium ions, tab sis ob zaug ntawm cov hydroxide ions. Tam sim no muab cov lej no tso rau hauv solubility khoom qhia thiab ua qhov sum.
Nyob rau hauv tas li ntawd, koj yuav nrhiav tau lub ntim ntawm ib tug hnyav npaum li cas?
Total mass - mass solute = mass kuab tshuaj . Hloov loj kuab tshuaj rau ntim los ntawm kev faib qhov loj ntawm cov ntxhiab los ntawm nws qhov ntom ntom.
Dab tsi yog units ntawm solubility?
Dej Solubility. Dej solubility yog ib qho kev ntsuas ntawm cov tshuaj lom neeg uas tuaj yeem yaj hauv dej ntawm qhov kub thiab txias. Chav tsev ntawm solubility feem ntau yog nyob rau hauv mg / L (milligrams per litre ) los yog ppm (qhov ib lab). Feem ntau koj tuaj yeem pom nws hauv ntu 9 ntawm daim ntawv qhia kev nyab xeeb (SDS).

Yuav ua li cas ntxiv tus inhibitor cuam tshuam tus nqi ntawm cov tshuaj tiv thaiv?
Kev piav qhia: Los ntawm txhais, inhibitors qeeb cov tshuaj tiv thaiv. Yog li ntawd, yog tias koj yuav tsum ntxiv ib qho inhibitor rau cov tshuaj tiv thaiv, koj yuav ua rau tus nqi ntawm cov tshuaj tiv thaiv txo. Cov tshuaj no ceev cov tshuaj tiv thaiv, yog li nce cov tshuaj tiv thaiv
Yam dab tsi tuaj yeem hloov pauv yog tias koj xav nce tus nqi ntawm cov tshuaj tiv thaiv tshuaj?
Cov yam ntxwv uas cuam tshuam rau cov tshuaj tiv thaiv yog: thaj tsam ntawm cov khoom reactant. concentration los yog siab ntawm ib tug reactant. kub. xwm ntawm cov reactants. muaj/tsis muaj catalyst
Yuav ua li cas koj thiaj nrhiav tau tus nqi ploj ntawm tus nqi tsim?
Tus nqi ntawm ib qho tshuaj tiv thaiv yog qhov kev hloov hauv kev concentration ntawm qhov kev hloov ntawm lub sijhawm. Cov tshuaj tiv thaiv tuaj yeem txhais tau li no: tus nqi ploj ntawm A tus nqi = −Δ [A] Δt. tus nqi ploj ntawm B tus nqi = − Δ [B] Δt. tus nqi tsim ntawm C tus nqi = Δ [C] Δt. tus nqi tsim ntawm D) tus nqi = Δ [D] Δt
Yuav ua li cas koj yuav soj ntsuam cov nyhuv ntawm lub teeb siv ntawm tus nqi ntawm photosynthesis?
Cov nyhuv ntawm lub teeb siv ntawm photosynthesis tuaj yeem tshawb xyuas hauv cov nroj tsuag dej. Qhov kev siv lub teeb yog proportional rau qhov kev ncua deb - nws yuav txo qis raws li qhov deb ntawm lub teeb nce - yog li lub teeb siv rau kev tshawb nrhiav tuaj yeem sib txawv los ntawm kev hloov qhov kev ncua deb ntawm lub teeb mus rau cov nroj tsuag
Yuav ua li cas cov khoom tsim tawm ib feeb cuam tshuam rau tus nqi ntawm cov tshuaj tiv thaiv enzyme catalyzed?
Rau ib qho enzyme catalyzed cov tshuaj tiv thaiv, tus nqi feem ntau yog qhia nyob rau hauv tus nqi ntawm cov khoom tsim tawm ib feeb. Thaum qhov kub thiab txias, qhov cua sov feem ntau nce tus nqi ntawm cov enzyme catalyzed cov tshuaj tiv thaiv vim tias cov reactants muaj zog ntau dua, thiab tuaj yeem ua tiav qhov ua kom muaj zog
