Hais txog qhov no, koj ua li cas sib npaug ntawm cov 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.
Qhov thib ob, qhov kev sib npaug yog dab tsi? A sib npaug equation yog ib qho kev sib npaug rau cov tshuaj tshuaj tiv thaiv nyob rau hauv uas tus naj npawb ntawm atoms rau txhua lub hauv paus tshuaj tiv thaiv thiab tag nrho cov nqi yog tib yam rau ob qho tib si reactants thiab cov khoom. Kuj Paub Raws li: Sib npaug qhov sib npaug, sib npaug tus tshuaj tiv thaiv , kev txuag nqi thiab huab hwm coj.
Tsis tas li ntawd kom paub yog, dab tsi yog cov cai rau ntsuas cov tshuaj sib npaug?
Ntsuas qhov sib npaug
- Siv txoj cai lij choj ntawm kev txuag ntawm pawg kom tau txais tib tus naj npawb ntawm atoms ntawm txhua lub ntsiab ntawm txhua sab ntawm qhov sib npaug.
- Thaum ib lub ntsiab lus sib npaug, mus rau qhov sib npaug, thiab lwm qhov, kom txog thaum tag nrho cov ntsiab lus sib npaug.
- Muab cov qauv tshuaj sib npaug los ntawm kev tso cov coefficients ua ntej lawv.
Cov tshuaj tiv thaiv kab mob sib txawv yog dab tsi?
Lub ntsiab plaub hom ntawm cov tshuaj tiv thaiv yog kev sib txuas ncaj qha, tsom xam tshuaj tiv thaiv , ib qho kev hloov pauv, thiab kev hloov pauv ob zaug. Yog koj raug nug tsib lub ntsiab hom ntawm cov tshuaj tiv thaiv , nws yog plaub thiab ces yog acid-base los yog redox (nyob ntawm seb leej twg koj nug).

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
Yuav ua li cas koj daws cov kab zauv sib npaug los ntawm graphical method?
Ib qho kev daws teeb meem tuaj yeem ua tau los ntawm tes (ntawm daim ntawv duab), lossis nrog kev siv lub tshuab xam zauv. Graphing ib qhov system ntawm linear equations yog yooj yim li graphing ob kab ncaj. Thaum cov kab yog graphed, qhov kev daws yuav yog tus (x, y) xaj khub uas ob kab sib tshuam (hla)
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
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
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
