Hāora allotropic whakarerekē: uara āhuatanga whakatairite me te

Ngota o tetahi ahua e taea e wahi o matū rerekē. Hoki te huānga denoted e te tohu «e» (lat. Taitara Oxygenium), e rua nuitia mohiotia i roto i te taonga ohie āhua. Ko te tātai o tetahi o ratou - e _2, te tuarua - e _3. tenei whakarerekētanga allotropic hāora (ngā pū-). He He iti pūmau (e, e _4, me te ₈₎ ētahi atu _pūhui. Hei mahino te rerekētanga i waenganui i enei momo e pai rāpoi rite me ngā āhuatanga o ngā matū.

He aha te mea allotropic whakarerekētanga?

Ka taea e maha ngā āhuatanga matū tīariari i roto i rua, e toru, neke atu rānei ngā puka. Ia o enei whakarerekētanga i hanga te o tetahi ngota ahua. Scientist J. Bertsellius i 1841 tuatahi fakamatala'i te allotropism āhuatanga. tauira Open tuatahi tono anake ki tohu te hanganga rāpoi o matū. Hei tauira, e rua mohiotia whakarerekē allotropic o te hāora, e ngota hanga te rāpoi ngota. I muri mai, ka kitea kairangahau kia whakarerekētanga i roto i te tioata. E ai ki ngā ariā hou, ko tetahi o nga take o te polymorphism allotropy. Ko te rerekētanga i waenganui i ngā puka tikanga meinga e te hanganga o here matū i roto i ngā rāpoi ngota me tioata. Tenei faaiteiteraa āhuatanga waiwai huānga 13-16 o te Taka Pūmotu.

Kia pehea te rerekē huinga o ngota kitea i roto i te āhuatanga o te mea?

whakarerekētanga Allotropic o te hāora, me te pekerangi e hanga e ngota huānga ki tau raupapa 8 me te taua maha o ngā irahiko. Ko e rerekē i roto i te hanganga ratou, hua i roto i te rerekētanga nui i roto i te āhuatanga.

Whakatau i runga i nga hua o te whakarite: te hāora allotropic kore whakarerekētanga e rerekē i roto i te hanganga kounga. pānga hanganga rāpoi nga āhuatanga ōkiko me te matū o te matū.

Ahakoa te nui o te hāora, me te pekerangi i roto i te āhua o te taua?

Taonga, tona tātai e ₂ puta i roto i te huru, te wai ōnuku, kirinuku me kaiao ora. Mō 20% o te kōhauhau i hanga rāpoi diatomic o te hāora. I roto i te kōhaupapa i te teitei o e pā ana ki 12-50 km i mata o te whenua ko te apa i huaina "whakangungu rakau pekerangi". whakaata Ko tōna hanganga te e tātai _3. Pekerangi tiaki to tatou paraneta, puai ngongo hihi katinga kino o te ra, me te tūāwhiorangi whero. Kei te rerekē haere tonu taonga kukū, me tona uara toharite he iti - 0,001%. Ko te kupu, e te _2, me te O ₃ - allotropic whakarerekē hāora he rerekētanga nui i roto i te tohatoha i te natura.

Me pēhea te ki te tiki i te hāora me te pekerangi?

hāora rāpoi - te taonga ohie tino nui i runga i te whenua. Kei te hanga e te reira i roto i te wahi matomato o ngā tipu ki te marama i roto i te tukanga o te ahotakakame. A, no te tukunga hiko o te take mai tūturu horihori ranei hāora diatomic pakaru rāpoi ngota. Ko te pāmahana i ai haamata te tukanga, ko e pā ana ki 2000 ° C. Radicals wāhanga puta hono ano ki te hanga i te hāora. huru ētahi momo kaha ki rāpoi diatomic o te hāora. I roto i tenei tauhohenga, kua whiwhi pekerangi, e tauhohe hoki ki te hāora Radicals free. Ko te kupu i reira he rāpoi diatomic. hua tauhohe Reversible i e te kukū o te pekerangi kōhauhau huri tonu. I roto i te apa kōhaupapa hanganga titoa o te e ₃ rāpoi tika ki radiation hihi katinga i te ra. Te kore tenei whakangungu rakau paruru taea e hihi mōrearea tae te mata o te whenua, me te whakangaro i ngā puka ora katoa.

Allotropic akatuke'anga hāora me te whanariki

E huānga Chemical e (Oxygenium) ko S (pūngāwhā) whakaritea i roto i te rōpū kotahi o te taka pūmotu, kua āhuatanga ratou i te hanganga o te puka allotropic. Rāpoi ngota ki tau rerekē o ngota whanariki (2, 4, 6, 8) i raro i ngā āhuatanga tikanga, te tino pūmau - S8, e rite i roto i te āhua i te karauna. Ko te whanariki orthorhombic me monoclinic hangaia o taua rāpoi 8-ngota.

I te pāmahana o 119 ° C puka monoclinic kōwhai parauri puka papatipu Kaore - whakarerekētanga Paku. He nui i roto i te matū ariā me ngā mahi ā te ako o akatuke'anga allotropic o whanariki, me te hāora.

I roto i te tauine ahumahi whakamahi āhuatanga oxidative puka rerekē. Kei te whakamahia te Ozone mō te disinfection o te rangi, me te wai. Otiia i nohanga i runga 0,16 mg / m3, he kino ki te tangata, me te kararehe i tenei hau. hiahiatia hāora rāpoi te mo te respiration, e whakamahia ana e ia i roto i te ahumahi, me te rongoā. He wāhi nui i roto i ngā mahi ōhanga tākaro he allotrope o waro (taimana, graphite), he ūkuikui (ma, whero) me ētahi atu āhuatanga matū.
