Jiki Properties na oxygen

gabatarwar

Kowace rana muna numfashi bukata sosai-da iska mana. Shin ka taba yin mamaki yadda, daga abin da, ko kuma wajen da abin da abubuwa ne da iska? Mai cikinta nitrogen (78%), mafi oxygen ne (21%) kuma inert gas (1%). Ko da yake oxygen ba fi na asali ɓangare na iska, amma ba tare da shi, da yanayi, dã mun kasance a cikinsa. Godiya ga shi, akwai rai a duniya, kamar yadda nitrogen da kuma rare gas tare kuma dabam ne cutarwa ga mutane. Bari mu bincika da kaddarorin oxygen.

Jiki Properties na oxygen

Oxygen a cikin iska kawai wani bambanci, kamar yadda a cikin talakawa yanayi, shi ne mai gas ba tare da dandano, launi da kuma wari. Amma oxygen za a iya artificially canjawa wuri zuwa wasu jihohi na tari. Saboda haka, a -183 ^{° C} da shi ya zama ruwa, kuma a -219 ^{° C} taurare. Amma m da ruwa oxygen iya kawai samun wani mutum da yanayi, shi wanzu ne kawai a cikin gaseous jihar. Liquid oxygen ne kamar haka (duba hoto). A m kama da kankara.

The jiki Properties na oxygen - shi ne ma cikin tsarin da kwayoyin da sauki abubuwa. Biyu oxygen kwayoyin halitta ta samar da irin wannan abubuwa: oxygen (Ya ₂₎ da lemar sararin samaniya (Ya _3). Nuna a kasa shi ne mai model na oxygen kwayoyin.

Oxygen. sinadaran Properties

Abu na farko da cewa yana farawa da wani sinadaran halayyar da rabi - da wuri a cikin lokaci-lokaci tsarin D. I. Mendeleeva. Saboda haka, oxygen ne a cikin 2nd lokaci 6 babban subgroups na karkashin lamba 8. Its atomic nauyi - 16 amu, shi ne wani nonmetal.

A inorganic sunadarai ta binary mahadi da sauran abubuwa shiga zuwa raba aji na inorganic mahadi - oxides. Oxygen iya samar da wata guba fili tare da biyu karafa da kuma wadanda ba karafa.

Magana game da samun da shi a cikin dakin gwaje-gwaje.

Chemically da oxygen za a iya samu ta hanyar ruwa electrolysis, bazuwar na potassium permanganate, hydrogen peroxide, potassium chlorate, nitrate aiki karafa da kuma nauyi karfe oxides. Ka yi la'akari da halayen lokacin da yin amfani da kowanne daga cikin wadannan hanyoyin.

1. Electrolysis na ruwa:

2h ₂ Ya = 2h ₂ + ₂ Ya

2. bazuwar na potassium permanganate (potassium permanganate) tare da mai kara kuzari:

KMnO ₄ = K ₂ MnO _4, KMnO + ₂ + ₂ Ya

3. A bazuwar na potassium chlorate:

2KClO ₃ = 2KCl + 3O ₂

4. bazuwar na hydrogen peroxide (hydrogen peroxide):

H ₂ Ya ₂ = H ₂ Ya + O ₂

5. bazuwar daga m karfe oxides (msl, Mercury oxide):

2HgO = 2Hg + O ₂

6. bazuwar na aiki karfe nitrate (msl sodium nitrate):

2NaNO ₃ = 2NaNO ₂ + ₂ Ya

A amfani da oxygen

Tun da sinadaran Properties mu gama. Yanzu yana da lokaci don magana game da yin amfani da oxygen a rayuwar mutum. Yana ake bukata domin konewa na habaka cikin ikon da kuma dumama shuke-shuke. Ana amfani da, don samar da karfe daga ya da baƙin ƙarfe, da, da yankan da kuma waldi karfe. Oxygen masks da ake bukata domin wuta, domin iri iri cylinders amfani da ferrous da nonferrous metallurgy, kuma ko da a cikin yi da nakiyoyi. Har ila yau, a masana'antun sarrafa kayayyakin abinci, oxygen da aka sani a matsayin mai abinci ƙari E948. Da alama akwai wani masana'antu inda shi ya ba an yi amfani da, amma mafi muhimmanci wajen taka a magani. Akwai shi ne ake kira - "Medical Oxygen". Don oxygen ya dace da amfani, ta pre-matsa. The jiki Properties na oxygen taimakawa ga cewa shi za a iya matsa. A irin wannan tsari, shi ne adana a ciki a Silinda, kama da irin wannan.

Ana amfani da m kula da ayyukan a cikin na'ura don kula da rayuwar matakai a jikin wani marasa lafiya haƙuri, kuma lura da wasu cututtuka: decompression, pathologies daga cikin gastrointestinal fili. Tare da taimakon likitoci kowace rana ajiye mutane da yawa. A sinadaran da jiki Properties na oxygen taimakawa ga cewa shi ne amfani da haka yadu.
