Standard Kub thiab Siab. Standard kub yog sib npaug mus rau 0 ° C, uas yog 273.15 K. Standard Pressure yog 1 Atm, 101.3kPa los yog 760 mmHg los yog torr. STP yog qhov "standard" tej yam kev mob feem ntau siv rau kev ntsuas roj ceev thiab ntim. Ntawm STP , 1 mole ntawm cov roj occupies 22.4L.
Cov lus nug tseem yog, STP tus nqi yog dab tsi?
STP nyob rau hauv chemistry yog cov ntawv luv rau Standard Temperature thiab Pressure. STP Feem ntau yog siv thaum ua kev suav ntawm cov pa roj, xws li cov roj ntom ntom. Tus qauv ntsuas kub yog 273 K (0 ° C lossis 32 ° Fahrenheit) thiab tus qauv siab yog 1 atm siab.
Ib yam li ntawd, yog STP 25 lossis 0? Ob leeg STP thiab cov xwm txheej hauv lub xeev feem ntau yog siv rau kev suav kev tshawb fawb. STP stands rau Standard Temperature thiab Pressure. Nws txhais tau tias yog 273 K ( 0 degrees Celsius) thiab 1 atm siab (los yog 105 Pa). Kub tsis tau teev tseg, txawm hais tias feem ntau cov ntxhuav suav sau cov ntaub ntawv ntawm 25 degrees C (298 K).
Hais txog qhov no, koj yuav suav li cas STP?
Yog tias koj muaj qhov loj ntawm cov pa, koj tuaj yeem faib cov huab hwm coj los ntawm qhov hnyav molecular ntawm cov roj molecules kom tau txais cov lej ntawm moles. Tom qab ntawd muab qhov no los ntawm 22.4 Litres / mole kom tau txais qhov ntim.
Puas yog STP thiab NTP tib yam?
STP stands rau Standard Temperature thiab Pressure. NTP stands rau Normal Temperature thiab Pressure. STP yog teem los ntawm IUPAC li 0 ° C thiab 100 kPa lossis 1 bar. NTP yog teem rau ntawm 101.325 kPa tab sis siv 20 ° C raws li qhov kub thiab txias.

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
Koj tuaj yeem qhia tau li cas yog tias ob qhov sib npaug sib npaug?
Peb tuaj yeem txiav txim siab los ntawm lawv qhov sib npaug seb puas yog ob kab sib npaug los ntawm kev sib piv lawv cov nqes hav. Yog hais tias cov slopes yog tib yam thiab cov y-intercepts txawv, cov kab yog parallel. Yog tias txoj kab nqes sib txawv, cov kab tsis sib npaug. Tsis zoo li cov kab sib luag, cov kab perpendicular sib tshuam
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
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
