Ib lub tswv yim yooj yim heev thaum cuam tshuam nrog zog yog lub tswv yim ntawm kev sib npaug los yog tshuav nyiaj li cas. Yog qhov loj thiab kev taw qhia ntawm lub zog ua yeeb yam ntawm ib yam khoom yog qhov sib npaug, ces tsis muaj net zog ua yeeb yam ntawm cov khoom thiab cov khoom yog hais tias nyob rau hauv kev sib npaug.
Tsis tas li ntawd, koj yuav nrhiav tau lub zog sib npaug li cas?
Yog qhov khoom nyob ntawm kev sib npaug , ces net zog ua raws li qhov khoom yuav tsum yog 0 Newton. Yog li, yog tag nrho cov zog yog ntxiv ua ke ua vectors, ces tus resultant zog (tus vector sum) yuav tsum yog 0 Newton.
Cov xwm txheej rau equilibrium yog dab tsi? Ib yam khoom nyob hauv kev sib npaug yog; Lub resultant quab yuam ua rau cov khoom yog xoom. Tus lej ntawm lub sijhawm ua haujlwm ntawm ib qho khoom yuav tsum yog xoom.
Yog li ntawd, txoj cai sib npaug hais li cas txog lub zog?
yog li cov khoom uas muaj qhov nrawm nrawm kuj muaj xoom net sab nraud zog . Qhov no txhais tau tias tag nrho cov zog ua ntawm cov khoom yog sib npaug - uas yog hais , lawv nyob hauv kev sib npaug . Qhov no txoj cai kuj tseem siv tau rau kev txav mus rau hauv ib qho kev taw qhia tshwj xeeb. Xav txog ib qho khoom txav raws li x-axis.
3 hom equilibrium yog dab tsi?
Muaj peb hom equilibrium : ruaj khov, tsis ruaj khov, thiab nruab nrab. Cov duab thoob plaws qhov module no qhia txog ntau yam piv txwv.

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
Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Qhov sib npaug sib npaug rau qhov nruab nrab ntawm h2so4 los ntawm Koh yog dab tsi?
Hauv daim vis dis aus no peb yuav sib npaug ntawm qhov sib npaug KOH + H2SO4 = K2SO4 + H2O thiab muab cov coefficients raug rau txhua qhov sib xyaw. Txhawm rau sib npaug KOH + H2SO4 = K2SO4 + H2O koj yuav tsum nco ntsoov suav tag nrho cov atoms ntawm txhua sab ntawm cov tshuaj sib npaug
Dab tsi yog qhov sib txawv ntawm qhov sib txawv ntawm cov kab sib txuas thiab ntau qhov sib piv?
6. (2 lub cim) Qhov sib txawv ntawm cov kab sib txuas (kev sib piv) thiab ntau qhov sib piv yog dab tsi? Cov kab sib xyaw ua ke yog npaj sib piv; uas yog, tshwj xeeb txhais tau tias yog ua ke nyob rau hauv ntau txoj kev thiab contrasted nrog rau lwm yam kev sib txuas ntawm txhais tau tias
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
