Reactants yog cov khoom uas pib cov tshuaj tiv thaiv tshuaj, thiab cov khoom yog cov tshuaj tsim tawm hauv cov tshuaj tiv thaiv. Cov tshuaj tiv thaiv tshuaj tuaj yeem sawv cev los ntawm cov tshuaj formula: Reactants → Khoom. Bonds tawg thiab hloov kho thaum muaj tshuaj lom neeg.
Puas reactants ib txwm tsim cov khoom?
Hauv cov tshuaj tiv thaiv tshuaj, cov atoms thiab molecules uas cuam tshuam nrog ib leeg hu ua reactants. Hauv cov tshuaj tiv thaiv, cov atoms thiab molecules tsim los ntawm cov tshuaj tiv thaiv yoghu ua cov khoom. Hauv cov tshuaj tiv thaiv tshuaj, tsuas yog cov atoms tam sim no hauv cov reactants tuaj yeem xaus rau hauv cov khoom.
Dab tsi yog reagents reactants thiab cov khoom?
Reactants thiab reagents yog cov tshuaj uas siv los coj cov tshuaj tiv thaiv Ib tug reactant yog ib yam khoom uas tau noj los yog siv thaum lub sij hawm cov tshuaj tiv thaiv. Cov tshuaj uas tsim los ntawm cov tshuaj tiv thaiv yog hu ua cov khoom. Kev Ruaj Ntseg. Tsis yog txhua qhov tshuaj tiv thaiv tshwm sim ntawm tus nqi tib yam.
Puas yog reagents reactants?
Thaum qee zaus siv sib hloov nrog lo lus "reactant", reagents thiab reactants txawv heev. Hauv cov tshuaj tiv thaiv tshuaj, ib reagent khi rau ib yam dab tsi thiab yog li ua rau cov tshuaj tiv thaiv… Txawm li cas los xij, ib qho reactant tau noj. Ib qho reactant yog ib qho substrate hauv cov tshuaj tiv thaiv, qhov reagent yog ib qho catalyst.
piv txwv ntawm cov tshuaj reagents yog dab tsi?
Piv txwv ntawm cov npe reagents suav nrog Grignard reagent, Tollens 'reagent, Fehling's reagent, Millon's reagent, Collins reagent, thiab Fenton's reagentTab sis, tsis yog txhua tus reagents muaj lo lus "reagent" hauv lawv lub npe. Cov kuab tshuaj, enzymes, thiab catalysts kuj yog piv txwv ntawm cov tshuaj reagents.

Puas yog cov khoom lag luam nyiaj txiag nce cov tswv lag luam kev ncaj ncees?
Tsev Nyiaj Txiag yog ib qho kev sib npaug ntawm tus account uas tau sau tseg rau hauv tus tswv cuab qhov sib npaug ntawm daim ntawv tshuav nyiaj. Vim tias cov khoom lag luam nyiaj txiag sawv cev rau tus naj npawb ntawm cov khoom lag luam rov qab los ntawm kev lag luam qhib, nws txo tus tswv lag luam kev ncaj ncees los ntawm tus nqi them rau cov Tshuag .
Ntawm qhov sib npaug ntawm qhov sib npaug ntawm cov reactants) thiab cov khoom) yog qhov tas li?
Nyob rau hauv ib qho tshuaj sib npaug, cov tshuaj tiv thaiv rau pem hauv ntej thiab thim rov qab Cov tshuaj tiv thaiv rov qab yog ib qho reaction uas hloov dua siab tshiab ntawm reactants rau cov khoom thiab hloov cov khoom rau reactants tshwm sim ib txhij … Hauv qhov rov qab cov tshuaj tiv thaiv, hydrogen iodide decomposes rov qab rau hauv hydrogen thiab iodine.
Puas yog cov khoom lag luam newell yog cov khoom lag luam zoo los yuav?
NWL tam sim no ntaus pob ncaws pob Zacks Qib ntawm 2 (Yuav), nrog rau tus nqi qib ntawm A. Cov Tshuag muaj Forward P / E piv ntawm 14.76. Qhov no piv rau nws qhov kev lag luam qhov nruab nrab Forward P / E ntawm 22.55. Tshaj li 52 lub lis piam dhau los, NWL's Forward P/E tau siab li 17.
Dab tsi yog cov txiaj ntsig cuam tshuam nrog kev lag luam dawb thiab kev lag luam thoob ntiaj teb?
Nws tsav kev lag luam loj hlob, txhim kho kev ua tau zoo, nce kev tsim kho tshiab, thiab kev ncaj ncees ntau dua uas ua raws li cov cai raws li txoj caiCov txiaj ntsig no nce ntxiv raws li tag nrho kev lag luam-exports thiab imports-nce. Kev lag luam pub dawb nce nkag mus rau cov khoom zoo dua, tus nqi qis dua .
Vim li cas cov tuam txhab lag luam tseem ceeb rau cov lag luam?
Kev ua lag luam tseem ceeb, vim nws muaj muaj peev xwm txhim kho cov qauv kev ua neej thiab tsim kev nplua nuj, tsis yog rau cov neeg ua lag luam nkaus xwb tab sis kuj rau cov lag luam cuam tshuam. Cov neeg lag luam kuj tseem pab txhawb kev hloov pauv nrog kev tsim kho tshiab, qhov twg cov khoom tshiab thiab txhim kho kom muaj kev lag luam tshiab tsim .
