Yuav xam cov loj defect : ntxiv cov pawg ntawm txhua tus proton thiab ntawm txhua lub neutron uas tsim cov nucleus, rho tawm qhov tseeb pawg ntawm cov nucleus los ntawm kev sib xyaw pawg ntawm cov khoom kom tau txais cov loj defect.
Kuj kom paub yog, dab tsi yog qhov loj tsis xws luag?
Cov loj defect tuaj yeem suav nrog kev sib npaug Δm = [Z(mp + me) + (A - Z)m]-matom, qhov twg: Δm = loj defect [atomic pawg unit (amu)]; mp = pawg ntawm ib tug proton (1.007277 amu); m = pawg ntawm ib tug neutron (1.008665 amu); me = pawg ntawm ib tug electron (0.000548597 amu); matom = pawg ntawm nuclide X Z A (amu); Z = tus lej atomic
Ib yam li ntawd, puas yog qhov teeb meem loj tsis zoo lossis qhov zoo? Nuclear loj defect yog a tsis zoo tus nqi thiab muaj tib lub cim rau tag nrho cov ntsiab lus thiab yog li ntawd binding energies raws li lub zog uas ua kom lub nucleus ua ke yuav tag nrho cov muaj ib yam kos npe rau raws li xav. Ntawm qhov tod tes, tshuaj loj defect yog zoo rau ib txhia thiab tsis zoo rau lwm tus.
Tsuas yog li ntawd, dab tsi ua rau muaj qhov tsis xws luag?
A loj defect yog qhov txawv ntawm ib qho atom pawg thiab qhov sum ntawm cov pawg ntawm nws cov protons, neutrons, thiab electrons. Cov vim li cas qhov tseeb pawg yog txawv ntawm cov pawg ntawm cov khoom yog vim qee qhov pawg raug tso tawm raws li lub zog thaum protons thiab neutrons khi hauv atomic nucleus.
Vim li cas qhov tsis xws luag yog qhov tseem ceeb?
Loj Defect yog tus nqi ntawm cov teeb meem hloov mus rau lub zog ntawm kev tsim cov atomic nucleus. Ua rau yog ua kom muaj kev ruaj ntseg ntau dua nuclear teeb tsa.

Qhov loj ntawm daim teb hauv Millikan qhov kev sim roj poob tau txiav txim siab li cas?
Millikan roj-poob sim, thawj qhov ncaj qha thiab kev ntsuas ntawm cov nqi hluav taws xob ntawm ib qho hluav taws xob. Millikan tau ntsuas ob qho tib si ntawm qhov hluav taws xob quab yuam thiab qhov loj ntawm qhov hluav taws xob ntawm qhov me me ntawm cov roj tso tawm thiab los ntawm cov ntaub ntawv txiav txim siab qhov loj ntawm tus nqi nws tus kheej
Yuav ua li cas koj txiav txim siab npaum li cas ntawm cov kua qaub uas yuav tsum tau neutralize lub hauv paus?
Kev daws qhov teeb meem Acid-Base Neutralization Kauj Ruam 1: Muab xam cov moles ntawm OH-. Molarity = moles / ntim. moles = Molarity x Volume. moles OH- = 0.02 M/100 milliliters. Kauj ruam 2: Xam qhov ntim ntawm HCl xav tau. Molarity = moles / ntim. Volume = moles/molarity. Volume = moles H+/0.075 Molarity
Dab tsi txiav txim siab yooj yim npaum li cas magma ntws?
Ob qhov kub thiab ntxhia cov ntsiab lus ntawm magma cuam tshuam nws yooj yim npaum li cas. Lub viscosity (thickness) ntawm magma uas tawg los ntawm lub roob hluav taws cuam tshuam rau cov duab ntawm lub roob hluav taws. Lub roob hluav taws uas muaj qhov chaw siab tshaj yuav tsim los ntawm cov nplaum nplaum magma, thaum lub volcanoes flatter tsim los ntawm magma uas ntws yooj yim
Lub siab coefficient ntawm kev txiav txim siab txhais li cas?
Lub ntsiab lus ntawm Coefficient ntawm Kev Txiav Txim Nws muab koj lub tswv yim ntawm pes tsawg cov ntaub ntawv cov ntsiab lus poob rau hauv cov txiaj ntsig ntawm kab tsim los ntawm kev sib npaug regression. Qhov siab dua qhov coefficient, qhov feem pua ntawm cov ntsiab lus ntau dua cov kab dhau los thaum cov ntaub ntawv cov ntsiab lus thiab kab tau npaj
Yuav ua li cas koj txiav txim siab uas yog tus nqi txiav txim kauj ruam?
Tus nqi txiav txim siab kauj ruam yog kauj ruam qeeb tshaj plaws ntawm cov tshuaj tiv thaiv tshuaj uas txiav txim siab qhov nrawm (tus nqi) uas tag nrho cov tshuaj tiv thaiv ua tiav. Teb Tus nqi txiav txim kauj ruam yog kauj ruam thib ob vim nws yog kauj ruam qeeb. 2NO + 2H2 → N2 + 2H2O. Cov intermediates hauv cov tshuaj tiv thaiv no yog N2O2 thiab N2O
