Nuclear lwj . Radioactive lwj yog qhov txheej txheem ntawm ntau yam txheej txheem los ntawm qhov tsis ruaj khov atomic nucleusspontaneously emits subatomic hais. lwj yog hais tias tooccur nyob rau hauv niam txiv nucleus thiab tsim tawm ib tug ntxhais nucleus. Qhov feem ntau lwj hom yog alpha, beta, thiab gamma lwj.
Yog li ntawd, dab tsi yog tsim los ntawm nuclear lwj?
Radioactive lwj yog lub spontaneous tawg ntawman atomic nucleus ua rau kev tso tawm ntawm lub zog thiab teeb meem los ntawm lub nucleus. Nco ntsoov tias lub xov tooj cua isotope muaj unstablenuclei uas tsis muaj zog txaus los tuav lub nucleustogether.
Tsis tas li ntawd, lub zog dab tsi raug tso tawm thaum lub sijhawm hluav taws xob tawg? Cov lwj zog yog cov zog tso tawm bya radioactive lwj . Radioactive lwj yog cov txheej txheem uas tsis ruaj tsis khov atomic nucleus poob zog los ntawm emissionizing particles thiab hluav taws xob.
Hais txog qhov no, peb cov khoom ntawm cov khoom siv hluav taws xob puas yog dab tsi?
Ua ke, muaj peb hom loj ntawm nuclear lwj uas xov tooj cua Cov khoom tuaj yeem nkag mus: alpha, beta, lossis gamma lwj . Txhua hom emits ib particle los ntawm lub nucleus. Alpha hais yog high-zog helium nucleicontaining 2 protons thiab 2 neutrons.
Txoj kev lwj yog dab tsi?
Nuclear Cov txheej txheem lwj . Xov tooj cua lwj koom nrog cov emission ntawm ib tug particle thiab / los yog lub zog raws li ib tug atom hloov mus rau lwm yam. Feem ntau, lub atom hloov nws qhov chaw los ua ib lub caij tshiab.

Dab tsi yog cov hlau nplaum uas ua los ntawm qhov kev npaj ntawm electrons yog dab tsi?
Electrons yog teem rau hauv plhaub thiab orbitals nyob rau hauv ib tug atom. Yog hais tias lawv sau lub orbitals kom muaj ntau spin taw tes rau hauv qab (los yog vice versa), txhua atom yuav ua zoo li ib tug me me hlau nplaum. Thaum ib daim ntawm cov hlau tsis muaj hlau nplaum (lossis lwm yam khoom siv ferromagnetic) raug rau sab nraud magnetic teb, ob yam tshwm sim
Dab tsi yog qhov kev sib txuas ua haujlwm ntawm nucleolus nuclear pores thiab nuclear membrane?
Dab tsi yog qhov kev sib txuas ua haujlwm ntawm nucleolus, nuclear pores, thiab daim nyias nyias? A. Lub nucleolus muaj tus xa xov RNA (mRNA), uas hla lub hnab ntawv nuclear los ntawm lub qhov pores nuclear
Qhov kev sib npaug twg yog qhov tsim nyog los suav cov cua sov uas tsim los ntawm HCl NaOH cov tshuaj tiv thaiv?
Xam cov naj npawb ntawm moles ntawm lub hauv paus koj ntxiv los txiav txim siab molar tshav kub ntawm qhov nruab nrab, qhia siv qhov sib npaug Δ H = Q ÷ n, qhov twg 'n' yog tus naj npawb ntawm moles. Piv txwv li, xav tias koj ntxiv 25 mL ntawm 1.0 M NaOH rau koj HCl los ua kom muaj cua sov ntawm nruab nrab ntawm 447.78 Joules
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
Dab tsi yog txhais los ntawm lub sij hawm dissociation thiab dab tsi yog ib qho piv txwv ntawm cov khoom uas dissociates?
Dissociation, nyob rau hauv chemistry, sib cais ntawm ib yam khoom mus rau hauv atoms los yog ions. Thermal dissociation tshwm sim ntawm qhov kub thiab txias. Piv txwv li, hydrogen molecules (H 2) dissociate rau hauv atoms (H) ntawm kub heev; ntawm 5,000 ° K txog 95% ntawm cov molecules hauv cov qauv ntawm hydrogen yog dissociated rau hauv atoms
