Kev siv ntawm osmium
Vim nws qhov ntom ntom, osmium feem ntau yog alloyed nrog lwm cov hlau muaj nuj nqis los ua cov khoom xws li ntsuas pivots, phonograph koob, thiab hluav taws xob tiv tauj. Thaum ib txwm ua ke nrog iridium, nws yog siv hauv cov lus qhia tus cwj mem.
Ib yam li ntawd, nws raug nug, osmium siv rau dab tsi?
Nws yog qhov ntom ntawm tag nrho cov ntsiab lus thiab yog ob zaug tuab li txhuas. Osmium tsuas muaj ob peb siv xwb. Nws yog siv los tsim cov alloys nyuaj heev rau cov tswv yim cwj mem, ntsuas pivots, koob thiab hluav taws xob tiv tauj. Nws kuj yog siv nyob rau hauv kev lag luam tshuaj raws li ib tug catalyst.
Ib tug kuj nug, osmium puas tuaj yeem tua koj? Hmoov tsis zoo, Osmium tsim ib tug phem compound, Osmium tetroxide, thaum raug cua. Osmium Tetroxide yog tshuaj lom, volatile, dej soluble, thiab xav tau tiag tiag tua koj . Qhov ntom ntawm Osmium yog 23 grams per Cubic centimeter.
Tom qab, lo lus nug yog, yuav ua li cas txaus ntshai yog osmium?
Osmium tetroxide yog heev volatile thiab nkag mus rau daim tawv nqaij yooj yim, thiab yog heev lom los ntawm nqus tau , noj , thiab kev sib cuag ntawm daim tawv nqaij. Cov huab cua tsis tshua muaj siab ntawm osmium tetroxide vapor tuaj yeem ua rau mob ntsws thiab tawv nqaij lossis qhov muag puas, thiab yog li ntawd yuav tsum tau siv rau hauv lub hood fume.
Osmium nyob qhov twg?
Qhov chaw. Osmium tshwm sim hauv iridosule thiab hauv platinum-cov kabmob dej xuab zeb hauv Urals, North Asmeskas , thiab South America . Nws kuj tseem pom muaj nyob hauv nickel-cov kabmob ores ntawm Sudbury, Ontario cheeb tsam nrog rau lwm cov hlau platinum.

Vim li cas qhov piv txwv tseem ceeb hauv kev lag luam zaub mov?
Kev kuaj cov zaub mov yog txheej txheem siv los xyuas tias cov khoom noj muaj kev nyab xeeb thiab tsis muaj cov kab mob phem, lossis nws tsuas muaj cov tshuaj ntxiv uas tau tso cai ntawm qib uas tau txais, lossis tias nws muaj cov qib zoo ntawm cov khoom xyaw tseem ceeb thiab nws cov ntawv tshaj tawm yog raug, los yog kom paub cov qib ntawm cov as-ham tam sim no
Vim li cas nws tseem ceeb kom paub tias koj txhais li cas ntxiv?
Txhais qhov seem. Kev txhais cov lus tseem ceeb yog qhov tseem ceeb thaum koj faib ua lej vim tias koj tuaj yeem tau txais qhov teeb meem tsis raug yog tias koj tsis txhais cov seem kom raug. Piv txwv li, nyob rau hauv ib lo lus teeb meem koj yuav tsum tau faib thiab faib tawm rau koj nrog ib tug seem thiab koj yuav tsum tau muab sau tseg
Vim li cas qhov tseem ceeb ntawm qhov tseem ceeb?
Thaum koj pom tus nqi kiag li hauv qhov teeb meem lossis qhov sib npaug, nws txhais tau hais tias txhua yam nyob hauv tus nqi tiag tiag yog qhov zoo. Cov txiaj ntsig tsis zoo feem ntau siv rau hauv cov teeb meem cuam tshuam nrog kev nyob deb thiab qee zaum siv nrog qhov tsis sib xws. Qhov ntawd yog qhov tseem ceeb uas yuav tsum nco ntsoov nws zoo li qhov deb ntawm xoom
Vim li cas cov nuj nqis tseem ceeb tseem ceeb thaum qhia txog kev ntsuas?
Cov duab tseem ceeb yog qhov tseem ceeb los qhia qhov tseeb ntawm koj cov lus teb. Qhov no yog qhov tseem ceeb hauv kev tshawb fawb thiab engineering vim tias tsis muaj cov cuab yeej ntsuas tuaj yeem ua qhov ntsuas nrog 100% precision. Siv cov nuj nqis tseem ceeb tso cai rau tus kws tshawb fawb paub tias cov lus teb meej npaum li cas, lossis qhov tsis paub meej npaum li cas
Yuav ua li cas yog vim li cas tus qauv ntawm ib qho enzyme tseem ceeb heev rau nws txoj haujlwm hauv cov khoom muaj sia?
Enzymes ua kom cov tshuaj tiv thaiv uas tshwm sim hauv cov hlwb. Qhov kev ua haujlwm no cuam tshuam ncaj qha rau lawv cov qauv, nrog rau txhua qhov enzyme tau tshwj xeeb zoo li tus ua kom muaj zog rau ib qho tshuaj tiv thaiv. Kev poob ntawm cov qauv ua rau poob haujlwm. - Kub, pH, thiab kev tswj cov molecules tuaj yeem cuam tshuam rau kev ua haujlwm ntawm cov enzymes
