Thaum cov hluav taws xob tam sim no dhau los ntawm kev daws teeb meem ntawm sodium chloride ntsev ces hydrogen gas yuav raug ntsuas ntawm qhov tsis zoo electrode piv txwv li cathode, thiab cov roj chlorine yuav tsim ntawm qhov zoo electrode piv txwv li anode. Ntawm anode cov tshuaj tiv thaiv yog li: $2C{l^ - } to C{l_2} + 2{e^ - }$.
Qhov twg tshwm sim ntawm anode thaum lub sij hawm electrolysis ntawm fused NaCl?
Hint: Cov electrolysis ntawm fused NaCl yog siv rau kev tsim cov hlau Na. Oxidation tshwm sim ntawm anode thiab txo qis yuav tshwm sim ntawm cathode.
Nws yog tsim los ntawm electrolysis ntawm fused NaCl:-?
》Plag - Thaum lub sij hawm electrolysis ntawm fused sodium chloride, sodium uas tsim an Cation yog tso rau hauv Cathode thiab chlorine uas tsim cov anion tso ntawm anode. Yog li, los ntawm cov tshuaj tiv thaiv no, peb tuaj yeem hais tias Na yog hloov zuj zus ntawm Cathode.
Qhov twg tshwm sim ntawm anode thaum lub sij hawm electrolysis?
Cov tshuaj tiv thaiv ntawm lub anode yog oxidation thiab qhov ntawm cathode yog txo. Ntawm no, lub anode yog qhov zoo thiab cathode yog qhov tsis zoo electrode. Cov tshuaj tiv thaiv ntawm anode yog oxidation thiab hais tias ntawm cathode yog txo. Cov electrons yog muab los ntawm hom tau oxidized.
Nyob rau hauv cov txheej txheem twg fused NaCl yog Electrolysed?
Sodium hlau yog muab rho tawm los ntawm "Cov Txheej Txheem", ntawm kev lag luam. -Down tus txheej txheem yog raws li lub hauv paus ntsiab lus ntawm electrolysis ntawmfused los yog molten Sodium Chloride (NaCl). Down lub cell nyob rau hauv uas cov txheej txheem no tshwm sim, muaj ib lub thawv ntawm steel.

Cov tshuaj tiv thaiv dab tsi rau kev txhaj tshuaj tiv thaiv thib ob?
Cov tshuaj tiv thaiv COVID-19 thib ob yog dab tsi? Cov kev mob tshwm sim feem ntau tom qab koob thib ob yog qhov mob ntawm qhov chaw txhaj tshuaj (92.1% tshaj tawm tias nws kav ntev dua 2 teev); qaug zog (66.4%); mob lub cev lossis leeg nqaij (64.
Puas yog lub cev tiv thaiv kab mob hauv lub cev puas tsim cov tshuaj tiv thaiv?
Lub cev tiv thaiv kab mob tau txais, nrog kev pab los ntawm lub cev hauv lub cev, tsim cov hlwb (tshuaj tiv thaiv kab mob) los tiv thaiv koj lub cev los ntawm ib tus neeg invader tshwj xeeb. Cov tshuaj tiv thaiv no yog tsim los ntawm cov hlwb hu ua B lymphocytes tom qab lub cev tau raug rau cov neeg ua phem.
Thaum lub sijhawm tiv thaiv kev tiv thaiv kev nyab xeeb?
Yuav ua li cas tiv thaiv hypothermia Hnav khaub ncaws sov, ntau txheej nrog kev tiv thaiv tes thiab ko taw zoo (tsis txhob txwv lub dab teg ntau dhau, thom khwm, thiab khau). Hnub sov lub taub hau. … Yog ua tau, hloov khaub ncaws qhuav thaum twg khaub ncaws ntub.
Vim li cas cov tshuaj tiv thaiv combustion yog cov tshuaj tiv thaiv oxidation?
Kev sib xyaw ua ke ib txwm ua rau muaj oxygen lossis huab cua. … Hauv combustion cov tshuaj tiv thaiv oxygen yog ua ke nrog cov roj qhov chaw feem ntau carbon thiab hydrogen raws li ua rau carbon dioxide thiab dej thiab yog li qhov no yog cov tshuaj tiv thaiv oxidation.
Cov tshuaj twg yog cov tshuaj uas tsis yog tshuaj tiv thaiv inflammatory analgesic?
Txhua yam koj yuav tsum paub txog NSAIDs. Nonsteroidal anti-inflammatory tshuaj (NSAIDs) yog cov tshuaj uas txo qis lossis txo qhov mob. Cov piv txwv nrov tshaj plaws ntawm cov tshuaj hauv pawg no yog aspirin thiab ibuprofen. NSAIDs tuaj nyob rau hauv lub ntsiab lus dav ntawm non-opioid analgesics.
