Nruam spectrum :ib spectrum uas muaj tag nrho cov wavelengths uas tsis muaj qhov sib txawv ntawm qhov dav. Emission spectrum : Thaum ib qho hluav taws xob hauv lub xeev zoo siab txav mus rau qib qis zog, nws tso tawm ib qho ntawm lub zog li photons. Cov spectrum rau qhov kev hloov no muaj cov kab vim hais tias cov qib zog yog quantized.
Hauv qhov no, lub atomic emission spectra txawv li cas ntawm lub teeb pom kev txuas ntxiv?
Nruam spectrum ntawm dawb teeb tsuas yog deals nrog frequencies thiab wavelengths ntawm cov xim txuam nrog zaj sawv. Atomic emission spectrum deals nrog cov xim, frequencies, thiab wavelengths uas tso tawm los ntawm ib qho tshwj xeeb atom.
Ib yam li ntawd, koj yuav ua li cas sib txawv ntawm qhov txuas ntxiv thiab kab spectrum? Lub ntsiab qhov sib txawv ntawm qhov nruam spectrum thiab kab spectrum yog tias kab spectra tuaj yeem pom tias yog cais tawm emission kab los yog nqus kab , nrog loj qhov khoob nruab nrab lawv, hos nruam spectrum tsis muaj qhov khoob thiab tuaj yeem tsim los ntawm superimposing tso pa tawm thiab nqus tau spectrum ntawm tib yam
Yog li ntawd, qhov txawv ntawm qhov nruam thiab discrete spectra yog dab tsi?
Feem ntau ib tug tuaj yeem soj ntsuam ob chav kawm txawv ntawm spectrum : txuas ntxiv thiab tsis paub meej . Rau ib nruam spectrum , lub teeb yog tsim los ntawm qhov dav, tsis tu ncua ntau yam xim (lub zog). Nrog discrete spectra , ib tug pom tsuas ci los yog tsaus kab ntawm txawv heev thiab sharply-txhais xim (lub zog).
Peb hom spectra yog dab tsi?
Feem ntau cov teeb pom kev zoo tuaj yeem muab faib ua peb hom: txuas ntxiv, nqus, thiab emission. Ib yam khoom kub, opaque, zoo li cov filament hauv ib qho incandescent teeb lub teeb , emits ib tug nruam spectrum, muaj lub teeb ntawm tag nrho cov wavelengths.

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
Yuav ua li cas yog lub sum ntawm cov atomic masses ntawm tag nrho cov atoms nyob rau hauv ib tug qauv rau ib tug compound?
Cov mis loj ntawm ib yam khoom yog qhov sib npaug ntawm qhov nruab nrab atomic masses ntawm txhua lub atom sawv cev hauv cov tshuaj formula thiab qhia nyob rau hauv atomic mass units. Cov mis loj ntawm covalent compound tseem hu ua molecular mass
Yuav ua li cas ib tug crystal ntawm alum txawv ntawm ib tug crystal ntawm poov tshuaj sulfate?
A) Teb yog: potassium aluminium sulfate yog siv lead ua nrog cubic qauv, potassium aluminium sulfate dodecahydrate (alum) yog hydrate (muaj dej los yog nws cov ntsiab lus)
Yuav ua li cas yog ib tug piv txwv ntawm ib tug rational naj npawb uas tsis yog ib tug tag nrho?
Tus lej "rational" yog qhov piv ntawm ob tus lej. Piv txwv li, cov hauv qab no yog cov lej rational, thiab tsis muaj leej twg yog tus lej: 1 / 2. 2 / 3
Yuav ua li cas ib tug geologist yuav qhia tau hais tias ib tug quav yog ib tug syncline thiab anti-line?
Geologic Structures (Part 5) Anticlines yog folds nyob rau hauv uas txhua ib nrab ntawm cov quav dips deb ntawm lub crest. Synclines yog folds nyob rau hauv uas txhua ib nrab ntawm cov quav dips mus rau lub trough ntawm lub quav. Koj tuaj yeem nco qab qhov sib txawv los ntawm kev ceeb toom tias anticlines tsim "A" zoo, thiab synclines tsim hauv qab ntawm "S."
