First: lub coefficients muab tus naj npawb ntawm cov molecules (los yog atoms) koom nrog hauv tshuaj tiv thaiv . Hauv qhov piv txwv tshuaj tiv thaiv , ob molecules ntawm hydrogen react nrog ib molecule ntawm oxygen thiab tsim ob molecules dej. Thib ob: lub coefficients muab tus naj npawb ntawm moles ntawm txhua yam khoom koom nrog hauv tshuaj tiv thaiv.
Ib yam li ntawd, dab tsi yog qhov tseem ceeb ntawm cov coefficients hauv kev sib npaug tshuaj sib npaug?
coefficients yog tseem ceeb los ua pov thawj txoj cai ntawm kev txuag ntawm pawg. Cov coefficients nyob rau hauv ib tug balanced tshuaj sib npaug qhia tus txheeb ze ntawm moles ntawm reactants thiab cov khoom.
Dhau li ntawm saum toj no, dab tsi yog qhov sib npaug ntawm cov coefficients? Hauv kev nthuav dav ntawm, yog tias yog qhov tsis tu ncua, ces qhov tseeb coefficient ntawm lub sij hawm yuav yog cov khoom ntawm thiab cov binomial coefficient rau lub sij hawm ntawd. CEEB TOOM: Cov sum ntawm cov coefficients ntawm yuav yog vim tag nrho cov hwj chim ntawm yuav ua rau ib tug - ua tus binomial coefficients thiab tiag coefficients sib npaug.
Tom qab ntawd, dab tsi yog sawv cev los ntawm cov lej coefficients uas tau muab tso rau hauv pem hauv ntej ntawm cov qauv hauv kev sib npaug sib npaug?
Cov cov lej muab tso rau pem hauv ntej ntawm cov qauv rau kev sib npaug hu ua coefficients , thiab lawv muab tag nrho cov atoms hauv a qauv . Yog li, lub cim "2 NaHCO3" qhia ob chav ntawm sodium bicarbonate, uas muaj 2 Na atoms, 2 H atoms, 2 C atoms, thiab 6 O atoms (2 X 3 = 6, the coefficient lub sij hawm subscript rau O).
Coefficients yog dab tsi?
Hauv lej, a coefficient yog ib qho kev sib txuam hauv qee lub sij hawm ntawm polynomial, series, lossis ib qho kev qhia; nws feem ntau yog tus lej, tab sis tej zaum yuav yog ib qho kev qhia. Piv txwv li, yog tias y raug suav hais tias yog ib qho parameter hauv cov lus hais saum toj no, tus coefficient ntawm x yog −3y, thiab qhov tsis tu ncua coefficient yog 1.5 + y.

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
Koj tuaj yeem qhia tau li cas yog tias ob qhov sib npaug sib npaug?
Peb tuaj yeem txiav txim siab los ntawm lawv qhov sib npaug seb puas yog ob kab sib npaug los ntawm kev sib piv lawv cov nqes hav. Yog hais tias cov slopes yog tib yam thiab cov y-intercepts txawv, cov kab yog parallel. Yog tias txoj kab nqes sib txawv, cov kab tsis sib npaug. Tsis zoo li cov kab sib luag, cov kab perpendicular sib tshuam
Dab tsi yog qhov tseem ceeb ntawm cov coefficients hauv kev sib npaug sib npaug?
Coefficients yog ib qho tseem ceeb los ua pov thawj txoj cai ntawm kev txuag ntawm huab hwm coj. Cov coefficients nyob rau hauv ib qho kev sib npaug ntawm cov tshuaj sib npaug qhia cov txheeb ze ntawm moles ofreactants thiab cov khoom. Los ntawm cov ntaub ntawv no, lub Cheebtsam ntawm reactants thiab cov khoom yuav raug xam. Koj tuaj yeem txiav txim seb tus lej ntawm moles ntawm cov khoom
Cov coefficients hauv kev sib npaug tshuaj sib npaug qhia koj li cas txog cov reactants thiab cov khoom?
Cov coefficients ntawm kev sib npaug chemicalequation qhia peb cov txheeb ze ntawm moles ntawm reactants thiab cov khoom. Hauv kev daws teeb meem stoichiometric, kev hloov pauv ntawm moles ntawm reactants rau moles ntawm cov khoom raug siv. Hauv kev suav loj, cov molar loj yog xav tau los hloov cov huab hwm coj mus rau moles
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
