Neon kuj tseem siv los ua cov ntsuas hluav taws xob siab thiab hloov cov iav, cov khoom siv hluav taws xob, cov khoom siv dhia dej thiab lasers. Liquid neon yog ib qho tseem ceeb ntawm cov tub yees txias. Nws muaj ntau tshaj 40 npaug ntau dua lub tub yees rau ib chav tsev ntim tshaj li kua helium, thiab ntau dua 3 npaug ntawm cov kua dej.
Raws li, dab tsi yog cov khoom ntawm neon?
Cov khoom tseem ceeb ntawm neon muaj xws li hauv qab no:
- Nws yog ib qho xim tsis muaj xim, tsis muaj ntxhiab tsw ntxhiab inert gas.
- Nws hloov mus rau xim liab-txiv kab ntxwv hauv lub tshuab nqus tsev.
- Nws yog chemically inactive.
- Nws muaj cov kua dej qis tshaj plaws ntawm txhua lub caij.
Ib yam li ntawd, dab tsi yog 5 qhov tseeb nthuav txog Neon? Neon (Ne) yog cov xim tsis muaj xim, tsis yog xim hlau, cov pa roj heev uas muaj cov atomic naj npawb ntawm kaum. Cov tswv cuab ntawm noblegas kev faib tawm glows reddish txiv kab ntxwv nyob rau hauv lub tshuab nqus tsev raj. Nthuav Neon Qhov Tseeb : Thaum sim ua kua dej, Sir William Ramsay thiab Morris Travers nrhiav pom neon hauv 1898.
Ntxiv mus, dab tsi yog 5 siv rau neon?
Neon: siv
- siv los ua neon advertising kos npe, uas tso nyiaj rau nws siv loj tshaj plaws.
- siv los ua cov ntsuas hluav taws xob siab, cov khoom siv hluav taws xob, cov raj wavemeter, thiab cov raj TV.
- neon thiab helium yog siv los ua cov roj lasers.
- kua neon yog ib qho kev lag luam cryogenic refrigerant.
Peb siv neon nyob qhov twg?
Feem ntau Siv ntawm Neon Txawm li cas los xij, neon teeb los ntawm lwm cov pa roj thiab tsis tas yuav tsum tau neon . Lub ntsiab tseem yog siv inhelium neon lasers, TV tubes thiab yoj meter tubes. Nws kuj yog siv nyob rau hauv xob laim ntes. Qhov no yog siv tiv thaiv cov khoom siv hluav taws xob los ntawm xob laim.

Dab tsi yog cov khoom lag luam hauv kev sib npaug molecular rau kev ua tiav cov tshuaj tiv thaiv ntawm aqueous barium hydroxide thiab nitric acid?
Ba(OH)2 + 2HNO3 → Ba(NO3)2 + 2H2O. Barium hydroxide react nrog nitric acid los tsim barium nitrate thiab dej
Cov khoom twg yog cov piv txwv ntawm cov khoom siv tshuaj xyuas txhua yam uas siv?
Piv txwv ntawm cov khoom siv tshuaj muaj xws li flammability, toxicity, acidity, reactivity (ntau hom), thiab kub ntawm combustion. Hlau, piv txwv li, ua ke nrog oxygen nyob rau hauv lub xub ntiag ntawm dej los ua xeb; chromium tsis oxidize (Daim duab 2)
Yuav ua li cas cov khoom siv caj ces hauv txhua lub xov tooj tshiab tsim los ntawm kev faib tawm ntawm tes sib piv nrog cov khoom siv caj ces hauv lub xov tooj qub?
Mitosis tshwm sim nyob rau hauv ob lub nuclei uas zoo tib yam rau thawj nucleus. Yog li, ob lub hlwb tshiab tsim tom qab kev faib tawm ntawm tes muaj tib yam khoom siv caj ces. Thaum lub sij hawm mitosis, chromosomes condense los ntawm chromatin. Thaum saib nrog lub microscope, chromosomes pom nyob rau hauv lub nucleus
Dab tsi yog qhov txawv ntawm cov khoom siv organic thiab cov khoom siv organic?
Dab tsi yog qhov txawv ntawm cov khoom siv organic thiab organic teeb meem? Organic khoom yog txhua yam uas tseem muaj sia nyob thiab tam sim no nyob rau hauv lossis hauv av. Rau nws los ua cov organic teeb meem, nws yuav tsum tau decomposed rau hauv humus. Humus yog cov khoom siv organic uas tau hloov dua siab tshiab los ntawm cov kab mob mus rau lub xeev tsis muaj zog
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
