kev sib npaug . Ib piv txwv ntawm kev sib npaug yog nyob rau hauv kev lag luam thaum muab khoom thiab kev thov sib npaug. Ib piv txwv ntawm kev sib npaug yog thaum koj nyob twj ywm thiab khov kho. Ib piv txwv ntawm kev sib npaug yog thaum huab cua kub thiab cua txias nkag mus rau hauv chav nyob rau tib lub sij hawm kom lub zuag qhia tag nrho kub ntawm chav tsev tsis hloov hlo li.
Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog ib qho piv txwv ntawm kev sib npaug hauv lub neej txhua hnub?
Muaj ntau piv txwv ntawm chemical kev sib npaug nyob ib ncig ntawm koj. Ib piv txwv yog ib lub raj mis ntawm fizzy cooldrink. Hauv lub raj mis muaj carbon dioxide (CO2) yaj hauv cov kua. Kuj tseem muaj CO2 roj nyob hauv qhov chaw nruab nrab ntawm cov kua thiab lub hau.
Tsis tas li ntawd, qhov sib npaug hauv physics thiab piv txwv yog dab tsi? Ib kev sib npaug tau hais kom ruaj khov yog tias me me, sab nraud cuam tshuam los ntawm lub xeev tsim cov rog uas zoo li tawm tsam qhov kev hloov pauv thiab xa rov qab lub cev lossis cov khoom mus rau lub cev. kev sib npaug xeev. Piv txwv suav nrog qhov hnyav raug tshem tawm los ntawm lub caij nplooj ntoo hlav lossis lub cib dag ntawm ib theem.
Ntawm no, 3 hom kev sib npaug yog dab tsi?
Muaj peb hom equilibrium : ruaj khov, tsis ruaj khov, thiab nruab nrab. Cov duab thoob plaws qhov module no qhia txog ntau yam piv txwv.
Qhov kev sib npaug sib npaug yog dab tsi?
Ib qho tshuaj 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 mus tom ntej thiab thim rov qab cov tshuaj tiv thaiv tshwm sim ntawm tus nqi sib npaug.

Dab tsi yog ib qho piv txwv ntawm cov khoom sib txuas ntawm kev sib npaug?
Kev rho tawm (Tsis yog Commutative) Tsis tas li ntawd, kev faib, kev sib xyaw ntawm cov dej num thiab cov lej sib npaug yog ob qho piv txwv zoo uas tsis yog kev sib txuas
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
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 qee qhov piv txwv ntawm qhov sib npaug ntawm kev txav mus los?
Kev sib npaug ntawm Kev Sib Tw Rau Cov Khaub Ncaws Kev Ua Si nrawm nrawm, tsav tsheb, thiab txawm tias tsuas yog taug kev yog txhua txhua hnub piv txwv ntawm kev txav. Kev sib raug zoo ntawm cov khoom no yog hu ua qhov sib npaug ntawm kev txav
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
