Nine a me ka physical ka waiwai, a me nā palapala noi no o oxygen

Lau elementa- "chalcogen" (a laila, ua "hanau keleawe") poʻo ka papa kuhikuhiE subgroup VI pūʻulu (hou Mea Maluna - 16-la pūʻulu) o ka papa'āweʻaweʻa kemika nenoaiu. Ma waho luaipele, selenium, tellurium, a me ka ia no hoi pili i ka oxygen. E ka kālailai i au mamuli o ka waiwai o ka loa e like me ka hehee ai ma ka Honua, me ka pono me ke noi, a loaa ka oxygen.

Ke prevalence o ka hehee ai

Ka oxygen ma maʻiʻo ma ka pńpa ua 'ano 50%. He ma na nā minelala hao likeʻole i loko o ka palapala o ka oxides a me ka paʻakai.

Ma kekahi nā 'ano o ka o oxygen i komo i loko o ka Nine Inch haku mele' ana o ka wai - kona pakeneka mea ma kahi o 89%, a ma na keena o nā mea a pau e ola ana, he poe - mea kanu a me nā holoholona.

I ka lewa, i ka i oxygen mea i loko o ka noa moku'āina i loko o ka palapala o O2, e lawe ana i ka hapalima o kona haku mele 'ana, a ma ke ano o ka'okikene kolu - O3.

physical waiwai

Oxygen ma O2 mea he kinoea i loaa ole 'ia nā pōpō, hoao aku la, a me ka honi. Ma ka wai, iki wailana. Paila wahi - 183 degere ma lalo Aʻohe Kelekia. ʻO ka wai o oxygen mea uliuli ma ke kala, a me kona mauʻano he uliuli nā pōaka i loko o ka paa palapala. Ka mahele heheʻe i ka wahi o nā pōaka o ka oxygen ma ka 218,7 degere lalo Aʻohe Kelekia.

Nine Inch mall

I ka enaena, keia hehee ai reacts me na mea he nui na mea waiwai e like me ke hooheheeia, a nonmetals, ho okumu i ka ai-kapaia'okesaside - ai pili aku i nā kumu a me ka oxygen. Ke Nine Inch naoh ma a na kumu mua e hele mai me ka o oxygen, kapa'okesaside.

No kekahi laʻana,

4Na + O2 = 2Na2O

S + O2 = SO2

Kekahi o ka luna 'hui i pane koke me ka o oxygen, pela no hoi ho okumu i oxides:

CH4 + 2O2 = CO2 + 2H2O

2CO + O2 = 2CO2

Inā he waiwai reacts lohi me ka o oxygen, ka mea, ua kapaia kali'okesaside. No ka laʻana, i kēia kaʻina hana o ka decomposition o ka ai, awi aku.

Kaniak ka oxygen

Kēia Nine Inch hehee ai hiki ke loaa ma ke keʻena hoʻokolohua, a ma ka hanalima hana.

Makaukau no o oxygen i loko o ke keʻena hoʻokolohua ua lawe mai i loko o kekahi mau aoao:

1. Ma naoh o decomposition o potasiuma chlorate (potasiuma chlorate).

2. Ma ka decomposition o ka hydrogen peroxide ma ka paio hahana maoli nō ia i loko o ke alo o manganese'okesaside, e hana me ka hōʻeleu.

3. Ma decomposition o potasiuma permanganate.

Makaukau no o oxygen i loko o ka hana 'ana i mālamaʻia e ki ina hana:

1. No ka manao o oaoieei-oxygen ma ua loaa mai ke ea i loko o a kona maʻamau ka maʻiʻo o ma kahi o 20%, a laila, hapalima. No keia mea i ka lewa ua mua combusted, haawi ana i ka läÿau, me ka kinowai ka maʻiʻo o ma kahi o 54% oxygen, kinowai naikokene - 44%, a me ka wai a argon - 2%. A laila, e hoʻokaʻawale mau kinoea Via distillation kaʻina hoʻohana kŘpa a uuku spacing ma waena o ka baila aʻela i omaka o ka wai a ka oxygen a me ka wai a naikokene - hua 183 a me ka hua 198,5 degere, niioaaonoaaiii. Ua huli mai i ka naikokene evaporates mua ma mua o oxygen.

Hoikehonua, lako a hoʻolako i ka oxygen ma o kekahi maemae. Naikokene, a ua loaa ia ma ka mahele ana i ka wai a ea ua hoʻohana 'ia me ka maka mea i loko o ka hoʻololi kemikala o kona nā mea loaʻa.

2. Electrolysis o ka wai kekahi, oia ke loa maemae ka oxygen loa. Kēia hana i laha ma ka'āina me ka nui waiwai a me ka nike uila.

Ke hoʻohana no o oxygen

Oxygen ma o ke kumu nui hehee ai o ka waiwai i loko o ke ola o ko mākou Honua. Kēia kinoea, a ua hookomoia iloko o ka lewa ua hoopauia ma ke kaʻina kanu ka hanu, holoholona a me nā kānaka.

Kaniak oxygen ma ka nui loa no ia mau mea o ka kanaka hana e like me lapaau, kuʻihao a me ka mea hiki ke hooheheeia ana, inā he mālili, mokulele (no ka ha kanaka, a no ka kiko'ī), a me ka metallurgy.

Ma ke kaʻina o kanaka aayoaeuiinoe ka oxygen ma ua hoopauia i nui na mea - e laʻa me, ma ke ahi o mōʻalihaku: maoli kinoea, methane, lanahu, ka laau. Ma nā mea a pau kēia mau keʻano o ka hanaʻana hua kalapona'okesaside. A lohe o keia ano i hoomakaukau ai i ka aoao maoli kaʻina hana o ka paa ana o ka hui Via kāʻamaʻai, i lawe wahi ma uliuli kanu ma lalo o ka hana o ke Map. E like me ka hopena o kēia kaʻina, monakō koko ua hanaʻia, a laila, eʻai nō ia i ka mea kanu, e kūkulu lākou nā'aʻaʻa.
