Photochemical smog yog sib tov ntawm cov pa phem uas yog tsim thaum nitrogen oxides thiab volatile organic tebchaw (VOCs) hnov mob rau lub hnub ci, tsim kom muaj xim av daj ntseg saum lub nroog. Nws feem ntau tshwm sim nyob rau lub caij ntuj sov, vim hais tias yog thaum peb muaj hnub ci tshaj plaws. Cov pa phem thawj.
Hauv qhov no, smog yog dab tsi thiab nws tsim li cas?
Atmospheric pollutants los yog gases uas ua smog raug tso tawm hauv huab cua thaum cov roj hlawv. Thaum lub hnub ci thiab nws cov cua sov ua rau cov pa roj thiab cov khoom zoo hauv cov cua, smog yog tsim . Nws yog purely tshwm sim los ntawm huab cua paug.
Ib sab saum toj, txhais li cas los ntawm photochemical smog? Photochemical smog yog hom smog tsim thaum lub teeb ultraviolet los ntawm lub hnub reacts nrog nitrogen oxides nyob rau hauv qhov chaw.
Kuj tseem paub, dab tsi yog qhov ua rau photochemical smog?
Ib qho tshuaj tiv thaiv ntawm lub hnub ci ultraviolet hluav taws xob thiab qhov chaw muaj kuab paug nrog hydrocarbons thiab oxides ntawm nitrogen ua rau photochemical smog . Qhov no tshwj xeeb tshaj yog tshwm sim los ntawm lub tsheb tso pa tawm. Smog tuaj yeem tshwm sim thaum nruab hnub thiab hmo ntuj, tab sis photochemical smog tsuas yog tshwm sim nyob rau hauv lub xub ntiag ntawm tshav ntuj.
Photochemical smog yog dab tsi?
Photochemical smog yog ib qho kev sib xyaw ntawm cov pa phem uas tau hloov kho rau hauv cov tshuaj lom neeg ntxiv los ntawm kev raug tshav ntuj. Lub ntsiab Cheebtsam ntawm photochemical smog yog nitrogen oxides, Volatile Organic Compounds (VOCs), tropospheric ozone, thiab PAN (peroxyacytyl nitrate).

Dab tsi yog daim ntawv cog lus ionic thiab nws tsim li cas?
Ionic daim ntawv cog lus, tseem hu ua electrovalent bond, hom kev sib txuas tsim los ntawm electrostatic attraction ntawm oppositely them ions nyob rau hauv ib tug tshuaj compound. Xws li daim ntawv cog lus thaum lub valence (sab nrauv) electrons ntawm ib lub atom raug xa mus tas li mus rau lwm lub atom
Kame yog dab tsi thiab nws tsim li cas?
Kames yog mounds ntawm sediment uas tso rau pem hauv ntej ntawm ib tug maj mam yaj los yog nyob twj ywm glacier / daim ntawv dej khov. Cov sediment muaj cov xuab zeb thiab gravels, thiab tsim mus rau hauv mounds raws li cov dej khov yaj thiab ntau cov sediment tso rau saum cov khib nyiab qub
Dab tsi yog DNA zoo li cuam tshuam nws cov qauv tshuaj rau nws zoo li cas thaum muaj ntau ntawm nws yog clumped ua ke?
Hais txog nws cov qauv tshuaj rau nws zoo li cas thaum ntau nws yog clumped ua ke. DNA zoo li kab laug sab webs. DNA tau soluble hauv DNA extraction tsis yog li peb tsis pom nws. Thaum nws tau stirred rau hauv ethanol, nws clumped ua ke thiab tsim thicker thiab thicker strands loj txaus kom pom
Dab tsi yog photochemical smog ua los ntawm?
Qhov sib xyaw ntawm cov tshuaj phem no hu ua photochemical smog. Cov tshuaj hauv photochemical smog muaj xws li nitrogen oxides, Volatile Organic Compounds (VOCs), ozone, thiab PAN (peroxyacytyl nitrate). Nitrogen oxides feem ntau yog los ntawm lub cav ntawm lub tsheb thiab cov tsheb thauj khoom
Dab tsi yog ib qho dot thiab kab kos duab thiab nws tsim li cas?
Dot thiab cross diagrams Cov electrons los ntawm ib lub atom yog qhia raws li cov dots, thiab cov electrons los ntawm lwm lub atom yog qhia raws li crosses. Piv txwv li, thaum sodium reacts nrog chlorine, electrons hloov ntawm sodium atoms mus rau chlorine atoms. Daim duab qhia ob txoj hauv kev los sawv cev rau qhov kev hloov hluav taws xob no
