Yog hais tias cov tshuaj sib npaug tsis sib npaug Tom qab ntawd nws ua txhaum txoj cai lij choj ntawm Kev Tiv Thaiv MASS uas tau muab los ntawm Antoine Lavoiser, nws hais tias tus naj npawb ntawm cov atoms nyob rau sab reactant yuav sib npaug rau cov lej ntawm cov atoms hauv cov khoom ntawm tib lub ntsiab lossis peb tuaj yeem hais tias cov atoms tsis tuaj yeem ua tsis tau. raug puas tsuaj los tsis tau
Yog li ntawd, tag nrho cov tshuaj sib npaug sib npaug?
Yuav siv tau, tshuaj sib npaug yuav tsum yog ib txwm sib npaug . Sib npaug tshuaj sib npaug muaj tib tus lej thiab hom ntawm txhua lub atom ntawm ob sab ntawm lub kev sib npaug . Cov coefficients hauv a kev sib npaug yuav tsum yog qhov yooj yim tag nrho tus lej piv. Mass yeej ib txwm khaws cia rau hauv tshuaj cov tshuaj tiv thaiv.
Ib yam li ntawd, kuv yuav ua li cas sib npaug tshuaj sib npaug? Rau tshuav nyiaj li cas a tshuaj sib npaug , pib los ntawm kev sau cov naj npawb ntawm cov atoms hauv txhua lub caij, uas tau teev nyob rau hauv subscript ntawm txhua lub atom. Tom qab ntawd, ntxiv coefficients rau cov atoms ntawm txhua sab ntawm lub kev sib npaug rau tshuav nyiaj li cas lawv nrog tib lub atoms ntawm lwm sab.
Ib yam li ntawd, tib neeg nug, vim li cas cov tshuaj sib npaug yuav tsum sib npaug?
A chemical equation yuav tsum sib npaug vim txoj cai tswj kev ruaj ntseg yuav tsum tuav zoo thaum lub sij hawm ib tshuaj sib npaug . Sib npaug ntawm kev sib npaug yog tsim nyog vim hais tias atoms tsis yog tsim los yog puas thaum lub sij hawm ib tshuaj sib npaug.
Tus lej nyob rau pem hauv ntej ntawm cov tshuaj formula hu ua dab tsi?
Coefficients yog cov tus lej hauv pem hauv ntej ntawm cov qauv . Ua ntej: cov coefficients muab cov tus lej ntawm molecules (los yog atoms) koom nrog cov tshuaj tiv thaiv. Hauv qhov piv txwv cov tshuaj tiv thaiv, ob lub molecules ntawm hydrogen react nrog ib molecule ntawm oxygen thiab tsim ob molecules ntawm dej.

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
Vim li cas peb thiaj li hais txog kev txwv tsis pub muaj kev hais tawm thiab thaum twg peb yuav hais cov kev txwv?
Peb hais txog kev txwv vim nws yuav ua rau qhov sib npaug tsis tau txhais hauv qee qhov txiaj ntsig ntawm x. Qhov kev txwv ntau tshaj plaws rau cov lus qhia muaj nuj nqis yog N / 0. Qhov no txhais tau tias txhua tus lej muab faib los ntawm xoom tsis tau txhais. Piv txwv li, rau txoj haujlwm f(x) = 6/x², thaum koj hloov x = 0, nws yuav ua rau 6/0 uas tsis tau txhais
Yuav ua li cas koj paub yog hais tias ib yam khoom tshiab yog tsim nyob rau hauv ib tug tshuaj sib npaug?
Muaj cov cim qhia tias muaj tshuaj lom neeg tshwm sim. Npuas daim ntawv, ib tug roj yog muab tawm, thiab lub beaker tau kub heev. Lub cim tseem ceeb tshaj plaws uas muaj tshuaj lom neeg tshwm sim yog kev tsim cov tshuaj tshiab. Cov khoom tshiab yog cov pa roj carbon, lub nkig dub, thiab dej vapor, roj tsis muaj xim
Yog vim li cas sodium poov tshuaj twj tso kua mis suav hais tias yog ib qho kev thauj mus los uas cov kev taw qhia yog cov sodium thiab poov tshuaj tau pumped?
Sodium-Potassium Pump. Kev thauj mus los yog lub zog xav tau cov txheej txheem ntawm kev siv cov molecules thiab ions hla daim nyias nyias 'nce toj' - tiv thaiv kev sib tw gradient. Txhawm rau txav cov molecules tawm tsam lawv cov concentration gradient, yuav tsum muaj cov khoom siv protein
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
