Sodium cyanide yog siv ua lag luam rau fumigation, electroplating, extracting kub thiab nyiaj los ntawm ores, thiab tshuaj manufacturing.
Hais txog qhov no, dab tsi yog sodium cyanide siv rau hauv kev lag luam mining?
A sodium cyanide kev daws yog feem ntau siv mus leach kub los ntawm ore. Heap leaching: Hauv qhov qhib, cyanide kev daws yog sprayed tshaj loj heaps ntawm crushed ore kis atop loj sau pads. Cov cyanide dissolves kub los ntawm cov ore mus rau hauv cov tshuaj raws li nws trickles los ntawm lub heap.
Ib sab saum toj no, qhov txawv ntawm sodium cyanide thiab potassium cyanide yog dab tsi? Sodium thiab poov tshuaj cyanide yog ntsev, uas yog khov. Zyklon B yog lub ntiaj teb diatomaceous permeanted nrog hydrogen cyanide . Cov tshuaj lom ib feem ntawm cyanide yog cov cyanide anion. Dab tsi cov anion txuas nrog tsis yog qhov tseem ceeb yog toxicity.
Ib sab saum toj no, sodium cyanide ua li cas?
Ntau lawm thiab cov khoom siv tshuaj lom neeg Sodium cyanide yog ua los ntawm kev kho hydrogen cyanide nrog sodium hydroxide: HCN + NaOH → NaCN + H2O. Sodium cyanide reacts sai nrog muaj zog acids kom tso hydrogen cyanide . Cov txheej txheem txaus ntshai no sawv cev rau kev pheej hmoo tseem ceeb cuam tshuam nrog cyanide ntsev.
Dab tsi yog cov ntsiab lus hauv sodium cyanide?
Formula thiab qauv: Cov tshuaj formula ntawm sodium cyanide yog NaCN, thiab nws cov molar loj yog 49.01 g / mol. Nws yog ib qho ionic compound tsim los ntawm cov sodium kev (Na+) thiab cyanide anion (CN-), nyob rau hauv uas cov carbon muaj ib tug triple daim ntawv cog lus nrog cov nitrogen atom.

Dab tsi yog kev siv cov saw hlau nuclear siv rau?
Nuclear chain reaction. Nuclear chain reactions yog cov tshuaj tiv thaiv uas tau txais lub zog nuclear, feem ntau los ntawm nuclear fission. Cov kev cuam tshuam ntawm cov saw hlau no yog qhov muab cov chaw tsim hluav taws xob nuclear nrog lub zog uas tom qab ntawd hloov mus ua hluav taws xob siv los ntawm tib neeg
Dab tsi yog qhov teeb meem loj tshaj plaws ntawm kev siv cov kev tshawb fawb txog kev sib raug zoo?
Tej yam tsis zoo los yog kev tshawb fawb txog kev sib raug zoo muaj xws li: a. Lawv tsis tuaj yeem siv los tsim kom muaj kev sib raug zoo-thiab-tshuaj los yog kev coj ntawm kev cuam tshuam
Yog vim li cas sodium poov tshuaj twj tso kua mis suav hais tias yog ib qho kev thauj mus los uas cov kev taw qhia yog cov sodium thiab poov tshuaj tau pumped?
Sodium-Potassium Pump. Kev thauj mus los yog lub zog xav tau cov txheej txheem ntawm kev siv cov molecules thiab ions hla daim nyias nyias 'nce toj' - tiv thaiv kev sib tw gradient. Txhawm rau txav cov molecules tawm tsam lawv cov concentration gradient, yuav tsum muaj cov khoom siv protein
Dab tsi yog qhov sib npaug siv los xam tag nrho cov khoom siv hluav taws xob siv?
Cov mis uas txuas lub zog thiab lub zog yog: Zog = Lub Zog x Sijhawm. Chav tsev ntawm lub zog yog joule, lub zog ntawm lub zog yog watt, thiab chav tsev ntawm lub sijhawm yog qhov thib ob
Thaum sodium reacts nrog chlorine los tsim sodium chloride electrons poob los ntawm dab tsi?
Thaum sodium reacts nrog chlorine, nws hloov nws ib sab ntawm electron mus rau chlorine atom. Los ntawm kev poob ib qho hluav taws xob, sodium atom tsim cov sodium ion (Na +) thiab los ntawm kev txais ib qho hluav taws xob, cov tshuaj chlorine atom tsim cov tshuaj chloride (Cl-)
