Yttrium yog ib tug heev crystalline hlau-grey, tsis tshua muaj-lub ntiaj teb hlau. Yttrium yog ruaj khov nyob rau hauv huab cua, vim hais tias nws yog tiv thaiv los ntawm lub tsim los ntawm tsim ntawm cov yeeb yaj kiab oxide ruaj khov ntawm nws qhov chaw, tab sis oxidizes yooj yim thaum rhuab. Nws reacts nrog dej decomposing nws tso tawm hydrogen gas, thiab nws reacts nrog mineral acids.
Kuj tseem paub yog, yttrium ua li cas?
Yttrium hlau yog ua los ntawm kev txo yttrium fluoride nrog calcium hlau.
yttrium siv li cas hauv lub neej txhua hnub? Yttrium tuaj yeem yog siv raws li ib tug additive rau ntxiv dag zog rau cov hlau, xws li txhuas thiab magnesium alloys. Nws kuj yog siv los pab ua cov ntxaij lim dej microwave, kub-kub superconductors, oxygen sensors, dawb LED teeb, thiab hlau txiav lasers. Thaum ntxiv rau lub koob yees duab lo ntsiab muag, lub koob yees duab lo ntsiab muag ua rau kub thiab poob siab.
Yog li ntawd, lub npe yttrium los ntawm qhov twg?
Cov npe yog keeb kwm thiab los ntawm lub zos ntawm Ytterby, nyob rau hauv Sweden: nyob rau hauv 1787, tus naas ej chemist Arrhenius pom muaj ib tug tshiab mineral thiab hu ua nws ytterbite. Tom qab ntawd, Johan Gadolin nrhiav pom yttrium ua oxide nyob rau hauv Arrhenius tus qauv hauv xyoo 1789, thiab Ekeberg hu ua oxide tshiab ytria.
yttrium feem ntau pom nyob qhov twg?
Yttrium tsis yog pom nyob rau hauv qhov zoo li lub ntsiab dawb. Yttrium yog pom nyob rau hauv lub ores monazite xuab zeb [(Ce, La, etc.) PO4] and bastn°site [(Ce, La, etc.)(CO3F], ores uas muaj me me ntawm tag nrho cov tsis tshua muaj lub ntiaj teb hlau, nrog rau lwm yam ores.

Dab tsi yog qhov cuab yeej tsim nyog ua ntej kev tshawb xav ntawm tes yuav tsim tau?
Lub microscope yog tsim nyog ua ntej qhov kev xav ntawm tes yuav tsim. Peb tus kws tshawb fawb twg tau txais qhab nia rau cov pov thawj ncaj qha ua rau txoj kev xav ntawm tes? Matthias Schleiden, Theodor Schwann, thiab Rudolph Virchow peb yog txhua tus kws tshawb fawb uas tau pab txhawb txoj kev xav ntawm tes
Dab tsi yog qhov txawv ntawm kev xaiv khoom tsim thiab kev tsim noob caj noob ces?
Artificial xaiv xaiv rau cov yam ntxwv uas twb muaj nyob rau hauv ib hom, whereas genetic engineering tsim cov yam ntxwv tshiab. Hauv kev xaiv dag, cov kws tshawb fawb yug tsuas yog cov tib neeg uas xav tau qhov zoo. Los ntawm kev xaiv kev yug me nyuam, cov kws tshawb fawb muaj peev xwm hloov cov cwj pwm hauv cov neeg. Evolution tau tshwm sim
Qhov kev sib npaug twg yog qhov tsim nyog los suav cov cua sov uas tsim los ntawm HCl NaOH cov tshuaj tiv thaiv?
Xam cov naj npawb ntawm moles ntawm lub hauv paus koj ntxiv los txiav txim siab molar tshav kub ntawm qhov nruab nrab, qhia siv qhov sib npaug Δ H = Q ÷ n, qhov twg 'n' yog tus naj npawb ntawm moles. Piv txwv li, xav tias koj ntxiv 25 mL ntawm 1.0 M NaOH rau koj HCl los ua kom muaj cua sov ntawm nruab nrab ntawm 447.78 Joules
Lub chaw tsim hluav taws xob nuclear tsim tau li cas?
Nuclear fission tsim cua sov Reactors siv uranium rau nuclear roj. Cov uranium tau ua tiav rau hauv cov me me ceramic pellets thiab muab tso ua ke rau hauv cov raj hlau kaw hu ua roj rods. Lub tshav kub tsim los ntawm fission hloov cov dej mus rau hauv chav, uas tig lub turbine los tsim hluav taws xob tsis muaj carbon
Vim li cas thiaj nres thiab pib codons tsim nyog rau kev tsim cov protein?
Pib thiab nres codons yog ib qho tseem ceeb vim hais tias lawv qhia lub xov tooj ntawm tes machinery qhov twg yuav pib thiab xaus kev txhais lus, txheej txheem ntawm kev ua cov protein. Qhov pib codon cim qhov chaw ntawm qhov kev txhais lus rau hauv protein ntau pib. Qhov nres codon (los yog termination codon) cim lub vev xaib uas txhais lus xaus
