Ib yam li ntawd, koj tuaj yeem ua dab tsi nrog bismuth?
Bismuth Cov tebchaw yog siv los ua catalysts hauv kev tsim cov khoom siv hluavtaws thiab roj hmab. Thaum twg bismuth yog ua ke nrog lwm cov hlau xws li txhuas, tin, hlau thiab cadmium, nws ua cov alloys uas tsis tshua muaj melting cov ntsiab lus uas ua tau yuav siv tau nyob rau hauv hluav taws detectors thiab extinguishers.
Tsis tas li ntawd, cov ntsiab lus dab tsi bismuth txuas nrog? Bismuth reacts nyob rau hauv kev tswj tej yam kev mob nrog halogens fluorine, F2, chlorine, Cl2, bromine, ib2, thiab iodine, I2, los tsim cov trihalides bismuth (III) fluoride, BiF3, bismuth (III) chloride, BiCl3, bismuth (III) bromide, IB3, thiab bismuth (III) iodide, IB3.
Ib yam li ntawd, koj tuaj yeem nug, puas yog bismuth txaus ntshai los daws?
Bismuth hlau tsis suav nrog tshuaj lom andposes yam tsawg kawg nkaus kev hem thawj rau ib puag ncig. Bismuth compoundsgeneralally muaj tsawg heev solubility tab sis lawv yuav tsum yog tuav nrog kev saib xyuas, vim tias tsuas muaj cov ntaub ntawv txwv ntawm lawv cov teebmeem thiab txoj hmoo hauv ib puag ncig.
Puas yog bismuth yog cov khoom ruaj khov?
Bismuth tau ntev xav txog qhov keeb nrog lub siab tshaj plaws atomic mass uas yog ruaj khov , tab sis nyob rau xyoo 2003 nws tau pom tias muaj cov xov tooj cua tsis tshua muaj zog: nws tsuas yog cov isotope primordial, bismuth -209, decays ntawm alpha lwj nrog ib nrab-lub neej ntau tshaj li ib billion lub sij hawm kwv yees lub hnub nyoog ntawm lub ntiaj teb no.

Dab tsi yog cov xim muaj nyob rau hauv daim ntawv qhia kev phom sij rau kev noj qab haus huv hauv NFPA 704?
NFPA 704 pob zeb diamond kos npe siv los tso saib cov ntaub ntawv no muaj plaub ntu xim: xiav, liab, daj, thiab dawb. Txhua ntu yog siv los txheeb xyuas ib pawg sib txawv ntawm qhov muaj peev xwm txaus ntshai. Ntu xiav ntawm NFPA xim code cim qhia txog kev phom sij rau kev noj qab haus huv
Dab tsi yog lwm lub npe rau alpha particle uas tawm thaum lub sij hawm alpha lwj?
Alpha hais, tseem hu ua alpha rays los yog alpha hluav taws xob, muaj ob protons thiab ob neutrons khi ua ke rau hauv ib tug particle zoo ib yam li helium-4 nucleus. Lawv feem ntau tsim nyob rau hauv tus txheej txheem ntawm alpha lwj, tab sis kuj yuav raug tsim nyob rau hauv lwm txoj kev
Dab tsi yog alpha lwj hauv chemistry?
Alpha decay los yog α-decay yog ib hom ntawm radioactive decay nyob rau hauv uas ib tug atomic nucleus emits ib tug alpha particle (helium nucleus) thiab yog li transforms los yog 'decays' mus rau ib tug txawv atomic nucleus, nrog ib tug loj tus naj npawb uas yog txo los ntawm plaub thiab ib tug atomic nucleus. tus lej uas txo los ntawm ob
Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
Dab tsi yog cov ions nyob rau hauv siab tshaj plaws concentration nyob rau hauv lub extracellular kua?
Cov tshuaj no nyob rau hauv cov kua dej extracellular thiab intracellular. Nyob rau hauv cov kua dej extracellular, cov cation loj yog sodium thiab cov anion loj yog chloride. Qhov loj cation nyob rau hauv cov kua dej intracellular yog poov tshuaj. Cov electrolytes no ua lub luag haujlwm tseem ceeb hauv kev tswj hwm homeostasis
