Cov kua qaub yog cov khoom uas thaum yaj hauv dej tso tawm hydrogen ions, H +(aq). Thaum twg yaj , bases tso tawm hydroxide ions, OH-(aq) rau hauv kev daws teeb meem. Dej yog cov product ib kua qaub thiab puag reacting. Chemists hais tias kua qaub thiab lub hauv paus tshem tawm lossis nruab nrab ib leeg, yog li cov tshuaj tiv thaiv hu ua "neutralisation".
Nyob rau hauv tas li ntawd, dab tsi yog ib tug acid thaum nws yaj nyob rau hauv dej?
Ib qho Arrhenius acid yog ib yam khoom uas ionizes thaum nws yaj hauv dej kom muab H+, los yog hydrogen , ib ion. Lub hauv paus Arrhenius yog ib yam khoom uas muab OH-, los yog hydroxide, ion thaum nws yaj hauv dej.
Qhov thib ob, puas tag nrho cov acids yaj hauv dej? Cov kua qaub thiab Bases hauv Dej . Cov kua qaub thiab bases yaj hauv dej thiab, vim hais tias lawv nce qhov concentration ntawm protons los yog hydroxide ions, lawv suppress dej tus kheej ionization. Rau ib qho twg kua qaub , Ka yog qhov equilibrium tas mus li kua qaub dissociation cov tshuaj tiv thaiv hauv dej.
Ua li no, thaum lub hauv paus yog yaj hauv dej dab tsi tawm?
1 Teb. Thaum pib yog yog yaj hauv dej dissociates tsim ib tug conjugate acid thiab conjugate puag . Lub conjugate puag thiab acid yog ions.
Lub hauv paus tshem tawm lossis lees txais dab tsi?
Hauv ntau qhov dav dav Brønsted-Lowry acid- puag txoj kev xav, a puag yog ib yam khoom uas muaj peev xwm txais hydrogen cations (H+)-lwm yam hu ua protons. Hauv Lewis qauv, a puag yog ib tug electron khub pub dawb.

Puas yog cua sov tso tawm thaum daim ntawv cog lus tsim?
Hauv txhua hom tshuaj tiv thaiv, daim ntawv cog lus tau tawg thiab rov ua dua los tsim cov khoom tshiab. Txawm li cas los xij, nyob rau hauv exothermic, endothermic, thiab tag nrho cov tshuaj tiv thaiv, nws yuav siv lub zog los rhuav tshem cov tshuaj uas twb muaj lawm thiab lub zog raug tso tawm thaum daim ntawv cog lus tshiab
Thaum tRNA tso nws cov amino acid dab tsi tshwm sim?
Thawj tRNA hloov nws cov amino acid mus rau cov amino acid ntawm lub tshiab tuaj txog tRNA, thiab ib tug tshuaj bond yog tsim los ntawm ob amino acids. Lub tRNA uas tau muab nws cov amino acid tso tawm. Tom qab ntawd nws tuaj yeem khi rau lwm cov molecule ntawm cov amino acid thiab siv dua tom qab hauv cov txheej txheem tsim cov protein
Dab tsi yog cov khoom ntawm phosphorous acid Dab tsi yog nws cov mis?
Phosphorous acid (H3PO3) tsim cov ntsev hu ua phosphites, kuj siv los txo cov neeg ua haujlwm. Nws yog npaj los ntawm dissolving tetraphosphorus hexoxide (P4O6) los yog phosphorus trichloride (PCl3) hauv dej
Dab tsi yog DNA zoo li cuam tshuam nws cov qauv tshuaj rau nws zoo li cas thaum muaj ntau ntawm nws yog clumped ua ke?
Hais txog nws cov qauv tshuaj rau nws zoo li cas thaum ntau nws yog clumped ua ke. DNA zoo li kab laug sab webs. DNA tau soluble hauv DNA extraction tsis yog li peb tsis pom nws. Thaum nws tau stirred rau hauv ethanol, nws clumped ua ke thiab tsim thicker thiab thicker strands loj txaus kom pom
Dab tsi yog qhov txawv ntawm cov tswv yim ua haujlwm thiab cov khoom tso tawm ua haujlwm?
Input ua hauj lwm yog ua hauj lwm ua nyob rau hauv ib tug machineas lub input quab yuam ua los ntawm lub input nrug.Qhov no yog nyob rau hauv sib piv rau cov zis ua hauj lwm uas yog ib tug quab yuam uas yog siv los ntawm lub cev los yog system rau lwm yam. Output work yog qhov ua haujlwm los ntawm lub tshuab ua haujlwm raws li cov zis tawm dag zog los ntawm qhov tso tawm qhov deb
