Cov tshuaj sib npaug yuav tsum tau sib npaug kom nws ua raws li txoj cai ntawm kev txuag ntawm huab hwm coj. A balanced tshuaj sib npaug tshwm sim thaum tus naj npawb ntawm cov atoms sib txawv ntawm cov khoom nyob rau hauv lub reactants sab yog sib npaug ntawm cov khoom sab. Sib npaug tshuaj sib npaug yog ib txoj kev sim thiab ua yuam kev.
Nyob rau hauv txoj kev no, qhov sib npaug ntawm cov tshuaj sib npaug yog dab tsi?
A kev sib npaug yog ib kev sib npaug rau a 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 tus kev sib npaug , sib npaug tus tshuaj tiv thaiv , kev txuag nqi thiab huab hwm coj.
Ib sab saum toj no, yuav ua li cas yog tias qhov sib npaug ntawm cov tshuaj tsis sib npaug? Tshuaj cov tshuaj tiv thaiv yuav tsum yog sib npaug , los yog nyob rau hauv lwm yam lus, yuav tsum muaj tib tus naj npawb ntawm ntau yam atoms nyob rau hauv cov khoom xws li nyob rau hauv cov reactants. Yog tias cov tshuaj tiv thaiv tsis sib npaug , tsis muaj ntaub ntawv hais txog kev sib raug zoo ntawm cov khoom thiab cov reactants tuaj yeem muab tau.
Hais txog qhov no, dab tsi yog cov kauj ruam hauv kev ntsuas tshuaj sib npaug?
Cov kauj ruam
- Sau koj qhov kev sib npaug. Rau qhov piv txwv no, koj yuav siv:
- Sau tus naj npawb ntawm atoms rau ib lub caij.
- Txuag hydrogen thiab oxygen rau qhov kawg, vim lawv feem ntau ntawm ob sab.
- Pib nrog ib lub ntsiab lus.
- Siv cov coefficient kom sib npaug ntawm ib qho carbon atom.
- Ntsuas cov hydrogen atoms tom ntej.
- Ntsuas cov pa oxygen atoms.
Vim li cas peb thiaj li yuav tsum sib npaug ntawm cov tshuaj sib npaug?
A chemical equation yuav tsum ua 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 atoms tsis yog tsim los yog puas thaum lub sij hawm ib tshuaj sib npaug.

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 txhua qhov sib npaug sib npaug sib npaug?
Thawj qhov sib npaug sib npaug yog qhov tseeb yog tias nws muaj kev txuag kom muaj nuj nqis. Piv txwv li, qhov sib npaug sib cais yeej ib txwm muaj tseeb, txij li lub ntsiab lus lawv yog ntawm daim ntawv: M(y) + N(t) = 0, yog li ϕ(t, y) = A(y) + B(t) yog a khaws cia kom muaj nuj nqis
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
Koj ua li cas sib npaug tshuaj sib npaug nrog cov lej oxidation?
Hauv txoj kev oxidation naj npawb, koj txiav txim siab oxidation tooj ntawm tag nrho cov atoms. Tom qab ntawd koj muab cov atoms uas tau hloov los ntawm cov lej me me. Koj tab tom ua tag nrho cov poob ntawm electrons sib npaug rau tag nrho qhov nce ntawm electrons. Tom qab ntawd koj sib npaug ntawm cov atoms
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
