Qhov no ib txwm tshwm sim thaum muaj kev cuam tshuam ncav cuag equilibrium . Tsis yog, tsis yog teeb meem los ntawm qhov kev taw qhia tus equilibrium txoj hauj lwm mus txog . Ob qho kev sim yuav muab tib yam equilibrium txoj hauj lwm vim tias ob qho kev sim pib nrog stoichiometric tus nqi ntawm cov reactants lossis cov khoom.
Ua raws li qhov no hauv kev txiav txim siab, txoj haujlwm sib npaug ntawm cov tshuaj tiv thaiv no cuam tshuam li cas?
Hauv kev sib npaug tshuaj tshuaj tiv thaiv Thaum tshav kub kub yog nyob rau sab reactants. Yog li, kev hloov pauv hauv qhov kub thiab txias coj qhov hloov pauv hauv qhov txoj hauj lwm ntawm kev sib npaug . Thaum qhov ntsuas kub qis dua, yuav muaj qhov tsis txaus ntawm cov cua sov uas yuav tsum tau ua tshuaj tiv thaiv . Yog li, cov kev sib npaug hloov mus rau sab laug kom offset cov nyhuv.
Tsis tas li ntawd, nyob rau hauv cov kev taw qhia twg yuav qhov sib npaug hloov yog NaOH ntxiv? sab laug
Tsis tas li ntawd, qhov kev taw qhia twg yuav ua rau muaj kev sib npaug?
Yog Q = Kua eq, cov tshuaj tiv thaiv yog nyob rau hauv equilibrium. Yog tias Q <Kua eq, cov tshuaj tiv thaiv yuav txav mus rau sab xis (hauv pem hauv ntej kev taw qhia) kom ncav cuag qhov sib npaug. Yog tias Q> Kua eq, cov tshuaj tiv thaiv yuav txav mus rau sab laug (nyob rau hauv qhov rov qab kev taw qhia) thiaj li mus txog equilibrium.
Qhov kub nce mus rau qhov sib npaug li cas?
Kev nce ntxiv tus kub txo tus nqi ntawm cov kev sib npaug tas li. Qhov twg cov tshuaj tiv thaiv pem hauv ntej yog endothermic, nce tus kub nce tus nqi ntawm cov kev sib npaug tas li. Txoj hauj lwm ntawm kev sib npaug kuj hloov yog koj hloov tus kub.

Dab tsi yog qhov txiaj ntsig tseem ceeb ntawm kev taw qhia ntawm tes los ntawm kev sib cuag lub cev ncaj qha?
Kev taw qhia kuj tshwm sim ntawm cov hlwb uas yog kev sib cuag ntawm lub cev. Kev sib cuam tshuam ntawm cov proteins ntawm qhov chaw ntawm cov hlwb tuaj yeem ua rau muaj kev hloov pauv hauv cov cwj pwm ntawm tes. Piv txwv li, cov proteins nyob rau saum npoo ntawm T-cells thiab antigen nthuav tawm cov hlwb sib cuam tshuam los ua kom muaj kev taw qhia hauv T-cells
Yuav daws qhov tsis sib npaug ntawm cov kab sib npaug thiab cov kab sib npaug sib npaug li cas?
Kev daws qhov tsis sib npaug ntawm qhov sib npaug yog zoo ib yam li kev daws cov kab sib npaug. Qhov sib txawv tseem ceeb yog koj tig lub cim tsis sib xws thaum faib lossis muab faib los ntawm tus lej tsis zoo. Graphing linear inequalities muaj ob peb qhov sib txawv ntxiv. Qhov uas yog qhov ntxoov ntxoo muaj xws li qhov tseem ceeb uas qhov kev tsis sib xws ntawm cov kab tawm muaj tseeb
Nws puas yuav ua rau pom qhov sib npaug ntawm kab sib npaug mus rau ib kab thiab los ntawm ib qho taw tes ntawm kab?
Qhov sib npaug ntawm ib kab uas yog parallel lossis perpendicular rau ib kab? Cov lus teb tau: Cov nqes hav ntawm cov kab sib npaug sib npaug. Hloov txoj kab nqes paub thiab cov kev sib koom ua ke ntawm ib qho taw tes ntawm lwm txoj kab rau hauv daim ntawv point-slope kom pom qhov sib npaug ntawm kab sib npaug
Puas yog nws ua tau rau ib qho kev sib npaug ntawm ob txoj kab sib npaug kom tsis muaj kev daws teeb meem piav qhia koj qhov laj thawj?
Cov kab ke ntawm kab sib npaug tuaj yeem tsuas muaj 0, 1, lossis ib qho kev daws teeb meem tsis kawg. Ob kab no tsis tuaj yeem hla ob zaug. Cov lus teb raug yog tias qhov system muaj ib qho kev daws teeb meem. Total Number of Points Number of 2-Point Baskets Number of 3-Point Baskets 17 4 (8 ntsiab lus) 3 (9 points) 17 1 (2 points) 5 (15 points)
Dab tsi yog qhov sib txawv ntawm cov kab lus sib npaug thiab qhov sib npaug sib npaug?
Cov kab lus sib npaug muaj qhov muaj txiaj ntsig zoo ib yam tab sis tau nthuav tawm nyob rau hauv ib hom ntawv sib txawv uas siv cov khoom ntawm cov lej xws li ax + bx = (a + b) x yog cov kab lus sib npaug. nruj me ntsis, lawv tsis yog 'sib npaug', yog li peb yuav tsum siv 3 kab sib luag hauv 'sib npaug' es tsis yog 2 raws li qhia ntawm no
