Yam khoom sib npaug thaum muaj qhov sib npaug ntawm qhov loj ntawm ob sab ntawm qhov taw tes nws yog sib npaug ntawm. Lub ntiajteb txawj nqus rub lub khoom down vim qhov loj thiab vim muaj qhov sib npaug ntawm qhov loj ntawm ob sab, lub zog ntawm lub ntiajteb txawj nqus yog tib yam ntawm ob sab. Vim tias txhua yam muaj qhov nruab nrab ntawm lub ntiajteb txawj nqus.
Tsis tas li ntawd, txoj cai ntawm kev sib npaug yog dab tsi?
Cov txoj cai rau ib yam dab tsi los ua sib npaug hu ua lub hauv paus ntsiab lus ntawm lub sij hawm thiab sau raws li nram no: Lub hauv paus ntsiab lus ntawm lub sij hawm. Thaum ib yam khoom yog sib npaug (nyob rau hauv equilibrium) cov sum ntawm lub clockwise lub sij hawm yog sib npaug zos rau cov sum ntawm lub anticlockwise lub sij hawm.
Kuj Paub, qhov hnyav li cas cuam tshuam rau kev sib npaug physics? Lub ntiajteb txawj nqus yeej ib txwm ua downward rau txhua yam khoom nyob rau hauv lub ntiaj teb no. Lub ntiajteb txawj nqus multiplied los ntawm cov khoom pawg tsim lub zog hu ua hnyav . Txawm tias lub zog ntawm ib yam khoom hnyav ua downward rau txhua qhov ntawm cov khoom, nws yog feem ntau suav hais tias ua raws li ib tug quab yuam los ntawm nws tshuav nyiaj li cas point, los yog qhov chaw ntawm lub ntiajteb txawj nqus.
Ib sab saum toj, yog qhov sib npaug ntawm physics?
NYIAJ : Ib cev yog sib npaug thaum nws nyob ruaj ruaj. Qhov ntawd txhais tau hais tias yuav tsum tsis muaj net quab yuam lossis torque. Yog li ntawd, txhua lub zog thiab / lossis lub zog ntawm lub cev yuav tsum raug tshem tawm lossis sib npaug los ntawm kev tawm tsam rog thiab / lossis torques.
Balance physics yog dab tsi?
Yog hais tias ob lub zog ntawm tus kheej muaj qhov sib npaug thiab qhov sib txawv, ces cov rog tau hais tias yog sib npaug . Ib yam khoom raug hais kom ua los ntawm lub zog tsis sib npaug tsuas yog thaum muaj ib tus neeg lub zog uas tsis yog sib npaug los ntawm lub zog ntawm qhov sib npaug ntawm qhov sib npaug thiab nyob rau hauv qhov sib txawv.

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
