Equilibria . Qhov no GCSE Chemistry quiz yog txhua yam hais txog kev sib npaug . Lo lus kev sib npaug txhais tau hais tias ib yam dab tsi nyob rau hauv lub xeev ntawm kev sib npaug. Hauv chemistry , nws hais txog qhov xwm txheej uas qhov concentrations ntawm cov reactants thiab cov khoom yog tas li.
Tsis tas li ntawd, dab tsi yog txhais los ntawm equilibrium hauv chemistry?
A tshuaj tiv thaiv yog nyob rau hauv kev sib npaug thaum cov concentrations ntawm reactants thiab cov khoom yog tas li - lawv qhov ratio tsis txawv. Lwm txoj kev ntawm kev txhais kev sib npaug yog hais tias ib tug system nyob rau hauv kev sib npaug thaum cov kev tshwm sim pem hauv ntej thiab rov qab tshwm sim ntawm qhov sib npaug.
Kuj Paub, Equilibrium ua haujlwm li cas hauv chemistry? Chemical equilibrium yog lub xeev ntawm cov tshuaj tiv thaiv rov qab uas tus nqi ntawm cov tshuaj tiv thaiv rau pem hauv ntej sib npaug ntawm tus nqi ntawm cov tshuaj tiv thaiv rov qab. Thaum ib qho tshuaj tiv thaiv nyob rau hauv kev sib npaug qhov concentration ntawm cov reactants thiab cov khoom yog tas li.
Tsuas yog li ntawd, qhov sib npaug ntawm BBC Bitesize yog dab tsi?
Dynamic kev sib npaug . Qhov no yog hu ua kev sib npaug txoj hauj lwm. Ntawm kev sib npaug qhov concentration ntawm reactant thiab cov khoom tseem nyob tas li tab sis tsis tas yuav sib npaug. Equilibrium tsuas tuaj yeem tau txais nyob rau hauv lub kaw lus kaw qhov twg cov tshuaj tiv thaiv yog nqa tawm hauv lub thawv ntim thiab tsis muaj cov tshuaj reactants lossis cov khoom ploj.
Le Chatelier lub hauv paus ntsiab lus hauv chemistry yog dab tsi?
Le Chatelier txoj cai yog kev soj ntsuam txog tshuaj equilibria ntawm cov tshuaj tiv thaiv. Nws hais tias kev hloov pauv hauv qhov kub, siab, ntim, lossis qhov siab ntawm lub kaw lus yuav ua rau muaj kev kwv yees thiab tawm tsam kev hloov pauv hauv lub cev kom ua tiav lub xeev sib npaug tshiab.

Dab tsi yog qhov txawv ntawm cov chemistry thiab organic chemistry?
Organic chemistry yog suav tias yog ib qho kev qhia ntawm chemistry. Thaum lub sij hawm lub kaus dav dav 'chemistry' yog kev txhawj xeeb nrog kev sib xyaw thiab kev hloov pauv ntawm txhua yam teeb meem, cov khoom siv tshuaj lom neeg tsuas yog txwv rau kev kawm ntawm cov organic tebchaw xwb
Dab tsi yog qhov quab yuam ntawm ib qho khoom hauv qhov zoo li qub lossis dynamic equilibrium?
Thaum lub net quab yuam ntawm ib yam khoom sib npaug rau zerothen cov khoom no yog nyob rau ntawm so (staticequilibrium) los yog txav ntawm qhov nrawm nrawm (dynamicequilibrium)
Dab tsi yog qhov txawv ntawm qhov zoo li qub thiab dynamic equilibrium hauv pob ntseg?
Lub pob ntseg tuav ob qho tib si zoo li qub thiab dynamic equilibrium. Static equilibrium yog kev saib xyuas ntawm lub taub hau txoj hauj lwm kom zoo nyob rau hauv cov lus teb rau cov kev hloov hauv linear motion xws li taug kev. Dynamic equilibrium yog kev saib xyuas ntawm txoj hauj lwm lub taub hau kom zoo nyob rau hauv cov lus teb rau rotational zog xws li tig
Dab tsi yog punctuated equilibrium hauv biology?
Punctuated equilibrium (tseem hu ua punctuated equilibria) yog ib txoj kev xav nyob rau hauv evolutionary biology uas tawm tswv yim tias ib zaug ib hom tshwm sim nyob rau hauv cov ntaub ntawv fossil cov pej xeem yuav ruaj khov, qhia me ntsis evolutionary hloov rau feem ntau ntawm nws cov keeb kwm geological
Nws txhais li cas hais tias ib yam dab tsi nyob rau hauv mechanical equilibrium?
Nyob rau hauv classical mechanics, ib tug particle yog nyob rau hauv mechanicalequilibrium yog hais tias lub net quab yuam ntawm cov particle yog xoom. Byextension, lub cev lub cev ua los ntawm ntau qhov chaw yog inmechanical equilibrium yog hais tias lub net quab yuam ntawm txhua qhov ntawm nws tus kheej qhov chaw yog xoom
