A reagent tswj yog a reagent ua rau tib formulation raws li ib pawg ntshav reagent tab sis tsis muaj cov ntshav tshwj xeeb antibody reactivity. Qhov tshwj xeeb ntawm kev sib raug zoo rau cov lus qhia no yog ib lo lus uas txhais tau tias muaj peev xwm ntawm a reagent los yog kuaj qhov system kom hnov lus xaiv.
Yog li ntawd, lub hom phiaj ntawm reagents yog dab tsi?
Reagent feem ntau hu ua cov khoom siv hauv cov tshuaj tiv thaiv tshuaj los kuaj xyuas, ntsuas, tshuaj xyuas lossis tsim lwm yam tshuaj. Vim yog cov tshuaj tiv thaiv nws ua rau, reagents Feem ntau yog siv nyob rau hauv kev tsom xam thiab synthesis. A reagent yog ib qho kev sib xyaw uas ntxiv rau hauv qhov system kom ua rau muaj tshuaj lom neeg.
Qhov thib ob, dab tsi yog cov reagents siv hauv chav kuaj? Reagent Piv txwv Nyob rau hauv cov organic chemistry, feem ntau yog cov organic molecules me me los yog inorganic compounds. Piv txwv ntawm reagents suav nrog Grignard reagent , Tollens' reagent , Fehling tus reagent , Collins reagent , thiab Fenton's reagent . Txawm li cas los xij, ib qho khoom yuav yog siv as a reagent tsis muaj lo lus " reagent "hauv nws lub npe.
Hais txog qhov no, dab tsi yog reagent hauv biology?
d??nt/ yog ib yam khoom lossis cov khoom sib txuas ntxiv rau hauv lub cev kom ua rau muaj tshuaj lom neeg, lossis ntxiv rau kev sim yog tias muaj cov tshuaj tiv thaiv tshwm sim. Cov ntsiab lus reactant thiab reagent feem ntau siv interchangeably-txawm li cas los xij, a reactant yog tshwj xeeb tshaj yog ib yam khoom noj nyob rau hauv cov chav kawm ntawm ib tug tshuaj tiv thaiv.
Kev npaj reagent yog dab tsi?
Abstract. Zoo li txhua txoj kev tshuaj ntsuam uas cuam tshuam nrog ntub chemistry pib nrog npaj reagent kev daws teeb meem. Qhov no feem ntau yog dissolving cov tebchaw nyob rau hauv cov kua los yog diluting los ntawm cov kev daws teeb meem. Npaj reagents ntawm qhov tseeb concentrations yog qhov tseem ceeb rau kev siv tau thiab rov ua dua ntawm txhua txoj kev tshuaj ntsuam.

Dab tsi yog tswj qhov muaj peev xwm coulometry?
Tswj muaj peev xwm coulometry: daim ntawv thov thib ob cov tshuaj tiv thaiv rau kev txiav txim siab ntawm plutonium thiab uranium ntawm cov khoom electrode. Kev txiav txim siab yog ua los ntawm kev sib xyaw ntawm sulfuric thiab nitric acids, thiab Ti (III) yog siv los txo plutonium thiab uranium rau Pu (III) thiab U (IV) ua ntej electrolysis
Dab tsi yog qhov tseem ceeb tshaj plaws reagent nyob rau hauv txoj kev Gram stain?
Lub ntsiab stain ntawm Gram txoj kev yog siv lead ua violet. Crystal violet qee zaum hloov nrog methylene xiav, uas zoo sib xws. Cov kab mob uas khaws cia cov siv lead ua violet-iodine complex tshwm ntshav xim av nyob rau hauv kev tshuaj xyuas microscopic
Dab tsi yog tus qauv rau lub limiting reagent?
Nrhiav qhov limiting reagent los ntawm saib cov lej ntawm moles ntawm txhua reactant. Txiav txim siab qhov sib npaug ntawm cov tshuaj sib npaug rau cov tshuaj tiv thaiv. Hloov cov ntaub ntawv allgiven rau hauv moles (feem ntau yuav, los ntawm kev siv molarmass ua qhov hloov pauv). Xam cov mole piv los ntawm cov ntaub ntawv muab
Dab tsi yog kev tswj zoo thiab kev tswj tsis zoo hauv gel electrophoresis?
Kev tswj qhov zoo thiab qhov tsis zoo yog cov qauv uas tau siv los lees paub qhov siv tau ntawm gel electrophoresis sim. Cov kev tswj tau zoo yog cov qauv uas muaj cov cim paub txog DNA lossis cov protein thiab yuav txav mus rau ib txoj hauv kev tshwj xeeb ntawm cov gel. Kev tswj tsis zoo yog cov qauv uas tsis muaj DNA lossis cov protein
Cov cai tswj kev tswj hwm yog dab tsi?
Kev hloov pauv hauv lub dav hlau sib koom tes feem ntau yog sawv cev los ntawm 'coordinate rules' ntawm daim ntawv (x, y) --> (x', y'). Qhov no txhais tau hais tias ib lub ntsiab lus uas nws cov kev tswj hwm yog (x, y) tau kos npe rau lwm lub ntsiab lus uas nws cov kev tswj hwm yog (x', y')
