Mphalandi chitsulo cholemera. Zitsulo zolemera zimatchula zitsulo zokhala ndi mphamvu yokoka yoposa 4 mpaka 5, ndipo kulimba kwa barium kuli pafupifupi 7 kapena 8, kotero barium ndi chitsulo cholemera. Barium mankhwala amagwiritsidwa ntchito kupanga mtundu wobiriwira mu zozinga moto, ndipo barium itha kugwiritsidwa ntchito ngati wogulitsa machubu a machubu a vacuum ndi casholitsani wopanga zitsulo zoyenga.
1 ndi barium chitsulo cholemera?Barium ndi chitsulo cholemera. Chifukwa: Zitsulo zolemera zimatchula zitsulo zokhala ndi mphamvu yayitali kuposa 4 mpaka 5, ndipo kulimba kwa barium kuli pafupifupi 7 kapena 8, kotero barium ndi chitsulo cholemera. Mafala Akutoma Nawo Barium ndi gawo logwira ntchito mu ma zitsulo padziko lapansi. Ndi chitsulo chofewa cha alkaline chofewa chokhala ndi lilevery yoyera. Mankhwala amagwira ntchito kwambiri, ndipo barum sanapezekenso mwachilengedwe. Minerals yodziwika kwambiri ya barium mu chilengedwe ndi barfate ndi barbote ndi ma carbonate, omwe ndi okhazikika m'madzi. Kugwiritsa Ntchito Barium: Ma Birailla Omwe Amagwiritsidwa Ntchito Kupanga Zobiriwira pamoto, ndipobarbium chitsuloItha kugwiritsidwa ntchito ngati wothandizira wogulitsa kuti achotse mpweya wa machubu a machubu a vacuum ndi cashopu thabu machubu, ndi wothandizitsa wazitsulo zoyenga bwino.
2 Kodi mabiramu ndi otani? Mphalandi gawo la mankhwala omwe ali ndi zilembo za keke. Barium ali ndi ntchito zambiri, ndipo zotsatirazi ndi zina mwazomwe zimagwiritsidwa ntchito:
1. Ma barium ndi zinthu zopangira ndi zowonjezera m'makampani. Mwachitsanzo, ma barium ndi omwe angagwiritsidwe ntchito kupanga mafoni opepuka, alawi a Flame, owonjezera ndi othandizira.
2. Barium ingagwiritsidwe ntchito kupanga machubu a X-ray, omwe amagwiritsidwa ntchito kwambiri m'minda yamankhwala ndi mafakitale. Chubu cha X-ray ndi chipangizo chomwe chimatulutsa X-ray for matenda owerengera komanso kuzindikira mapulogalamu.
3. Galasi lotsogolera la baruum limagwiritsidwa ntchito poyerekeza ndi galasi lamagalimoto, nthawi zambiri limakonda kupanga zida zowoneka bwino, matelescopes, ndi microscopic, etc.
4. Barium imagwiritsidwa ntchito ngati gawo lowonjezera komanso la alooy mu kapangidwe ka batire. Zimatha kusintha magwiridwe antchito ndi sitolo.
5. Barium mankhwala amagwiritsidwanso ntchito kupanga zinthu monga mankhwala ophera tizilombo, ma ceramic, ndi matepi amphamvu.
6. Ma barium mafuta amathanso kugwiritsidwa ntchito kuwongolera tizirombo ndi namsongole m'mawu ndi zipatso.
3 Kodi barium ion umakhala chiyani?Barium ion iyoni ndi iyoyo ya carbonate, sosungunuke ma ions, ndi ma iyofite. Barium ndi chinthu chachitsulo chapadziko lapansi, chimodzi mwa magawo asanu ndi chimodzi a gulu la Iia mu tebulo la nthawi yayitali, ndi chitsulo cham'dziko lapansi chofewa kwambiri, komanso chitsulo chofewa kwambiri. Minerals yodziwika kwambiri ya barium mu chilengedwe muli birite (barium sulfate) ndi Wifolite (Barium Carbonate), zonse zomwe zimakhazikika m'madzi. Barium was confirmed as a new element in 1774, but it was not classified as a metallic element until shortly after the invention of electrolysis in 1808. 4 Properties of barium Barium is a metallic element, silvery white, and emits a yellow-green flame when burning. Barrium mchere umagwiritsidwa ntchito ngati utoto wodekha kwambiri. Barium yachitsulo ndiyabwino kwambiri pakuyenga kwa mkuwa: Chakudya (njira yodziwira matenda ena a esophate, x-ray fluorcopy kapena mafinya amagwiritsidwa ntchito). Kachulukidwe ka 3.51 g / cm3. Malo osungunuka 725 ℃. Owiritsa 1640 ℃. Valence +2. Inozation Grance 5.212 Entrakron Volts. Mankhwala amakambitsidwa kwambiri ndipo amatha kuchitira ndi zitsulo zambiri. Kuwotcha kutentha kwambiri komanso kwa mpweya kumatulutsa barium peroxide. Amakhala oxidized osavuta ndipo amatha kuchitira ndi madzi kuti apange hydroxide ndi hydrogen. Imasungunuka mu acid kupanga mchere. Barrium mchere ndi poizoni kupatula barfate sulfate. Dongosolo lazitsulo ndi pakati pa potaziyamu ndi sodium.
