Cov Nernst equation muab cov txheej txheem rau kev sib txuas. Txij li thaum 1996, lub AP Examination tau muab qhov no kev sib npaug Hauv seem "Oxidation-Reduction; Electrochemistry" ntawm cov lus muab. Obviously siv cov Nernst equation nrog nws cov kev txwv ntau muab ntau lub cib fim rau cov tub ntxhais kawm yuam kev.
Cov lus nug tseem yog, puas yog Arrhenius sib npaug ntawm AP Chem kev kuaj mob?
Arrhenius equation yog dhau ntawm qhov kev kawm no thiab cov AP Exam . Lub tswv yim ntawm cov Arrhenius equation thiab kev txhais cov duab yog ib feem ntawm cov chav kawm. Txawm li cas los xij, suav nrog kev suav algorithmic tsis tau pom tias yog txoj hauv kev zoo tshaj plaws kom nkag siab tob txog cov tswv yim loj.
Kuj Paub, puas yog nuclear chemistry ntawm kev xeem AP? Tsis muaj nuclear chemistry ntawm kev xeem.
Kuj tseem xav paub, koj puas yuav tsum nco txog lub sijhawm AP chemistry?
Cov Lub Sijhawm Sijhawm (P. 1) muab rau ntawm AP kev xeem ua TSIS TAU muaj element cov npe sau tawm, tsuas yog siv cov cim. Yog li ntawd, koj yuav tsum paub txog lawv cov npe thiaj li siv tau daim ntawv qhia hnub ua tau zoo.
Nernst equation hauv chemistry yog dab tsi?
Hauv electrochemistry, lub Nernst equation yog ib kev sib npaug uas hais txog qhov txo qhov peev xwm ntawm ib qho electrochemical tshuaj tiv thaiv (ib nrab cell los yog puv cell tshuaj tiv thaiv ) mus rau tus qauv electrode peev xwm, kub, thiab kev ua ub no (feem ntau approximated los ntawm concentrations) ntawm cov tshuaj hom kev txo qis thiab oxidation

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 Goode's interrupted Homolosine projection ib qho kev pom zoo lossis sib npaug ntawm thaj tsam sib npaug?
Qhov cuam tshuam Goode Homolosine qhov projection (Goode's) yog qhov cuam tshuam, pseudocylindrical, thaj tsam sib npaug, sib xyaw daim ntawv qhia kev kwv yees uas tuaj yeem nthuav tawm tag nrho lub ntiaj teb ntawm ib daim ntawv qhia. Cov av loj thoob ntiaj teb tau nthuav tawm nrog lawv cov cheeb tsam kom raug, nrog kev cuam tshuam tsawg, thiab kev cuam tshuam tsawg kawg nkaus
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
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
