Chain Reactions Piv txwv
Cov tshuaj tshuaj tiv thaiv nruab nrab ntawm cov pa roj hydrogen thiab cov pa oxygen los ua dej yog lwm qhov piv txwv ntawm a chainreaction . Hauv tshuaj tiv thaiv , ib hydrogen atom yog hloov los ntawm lwm tus nrog rau ob OH radicals. Propagation ntawm cov tshuaj tiv thaiv tuaj yeem ua rau muaj kev tawg.
Tsis tas li ntawd, cov tshuaj tiv thaiv kab mob yog dab tsi?
chain reaction . Nyob rau hauv chemistry thiab physics, aself-sustaining series ntawm cov tshuaj tiv thaiv . Hauv ib chainreaction nyob rau hauv uranium-based nuclear reactor, piv txwv li, ib leeg neutron ua rau lub nucleus ntawm uranium atom toundergo fission. Nyob rau hauv tus txheej txheem, ob los yog peb ntxiv neutrons raug tso tawm.
Tsis tas li ntawd, kev tswj cov saw hlau li cas? Hauv kev ua haujlwm ntawm a nuclear reactor, fuelassemblies muab tso rau hauv qhov chaw thiab tom qab ntawd cov tswj rods maj mam nqa mus txog rau thaum a chain reaction tuaj yeem txhawb nqa. Raws li tshuaj tiv thaiv nce, tus naj npawb ntawm uranium-235 nucleidecreases thiab fission by-products uas nqus neutrons buildup.
Tsis tas li ntawd, dab tsi yog cov lus nug cov lus nug cov lus nug?
Nuclear Chain Reactions . -Nws yog thaum nqus cov neutron ua rau cov nucleus tawg. ~ ntau zog tso tawm. ~ tso tawm neutrons tuaj yeem nqus los ntawm lwm cov nuclei.
Yuav ua li cas koj nres ib tug chain reaction?
Tib txoj kev los tswj lossis nres ib tug nuclear chainreaction yog to nres cov neutrons los ntawm splitting moreatoms. Tswj cov pas nrig ua los ntawm cov khoom siv neutron-absorbing xws li asboron txo tus naj npawb ntawm cov neutrons dawb thiab coj lawv tawm ntawm tshuaj tiv thaiv.

Ib qho piv txwv ntawm cov tshuaj muaj zog hauv cov hluav taws xob tam sim no yog electroplating. Hauv cov txheej txheem no, muaj cov kua dej uas muaj hluav taws xob dhau mus. qhov no yog ib qho piv txwv ntawm kev siv tshuaj lom neeg hauv hluav taws xob tam sim no
Vim li cas cov tshuaj tiv thaiv kev zom zaub mov hu ua hydrolysis cov tshuaj tiv thaiv?
Thaum lub sij hawm zom mov, piv txwv li, decompositionreactions zom cov zaub mov loj rau hauv cov me me los ntawm kev ntxiv cov dej molecules. Hom tshuaj no hu ua hydrolysis. Raws li dej absorbs heatenergy, qee lub zog yog siv los rhuav tshem hydrogenbonds
Cov tshuaj tua kab mob twg thaiv cov kab mob protein ntau?
Tetracyclins yog ib hom tshuaj tua kab mob uas suav nrog cov thawj tetracycline nrog rau doxycycline thiab minocycline. Cov tshuaj tua kab mob no khi rau A qhov chaw ntawm 30s ribosome, tiv thaiv tRNA los ntawm kev nqa cov amino acids tshiab. Yog tias tRNA tsis tuaj yeem txuas mus rau ribosome, ces tsis muaj cov proteins tshiab tuaj yeem ua tau
Cov tshuaj tiv thaiv dab tsi yog qhov tshuaj tiv thaiv neutralization?
Neutralization yog ib hom tshuaj tiv thaiv nyob rau hauv uas muaj zog acid thiab muaj zog puag react nrog ib leeg los tsim dej thiab ntsev
Dab tsi yog tshuaj lom neeg cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv lub cev?
Qhov sib txawv ntawm cov tshuaj tiv thaiv lub cev thiab cov tshuaj tiv thaiv tshuaj yog muaj pes tsawg leeg. Hauv cov tshuaj tiv thaiv tshuaj, muaj kev hloov pauv ntawm cov tshuaj hauv nqe lus nug; nyob rau hauv ib qho kev hloov ntawm lub cev muaj qhov sib txawv ntawm qhov tsos, tsis hnov tsw, los yog cov duab yooj yim ntawm cov qauv ntawm cov teeb meem yam tsis muaj kev hloov pauv hauv cov ntsiab lus
