The lightest magasi. Properties rehydrogen, okisijeni uye senitrogen

Gas - mumwe inoti nyaya. Haana chaizvo vhoriyamu, achizadza yose mudziyo, riri. Asi ane fluidity uye arambe achirema. Ndezvipi chiedza magasi vari ikoko? Chii ivo yoku?

The lightest magasi

The zita "gasi" akashandurwa sezvaari kare XVII remakore, nokuda consonance shoko "mhirizhonga." Particulate nyaya uye zvechokwadi, tiri runobva. Vanotanga vari anongoitika kuti, kuchinja trajectory nguva dzose apo vakasangana pamwe nemumwe. Vanoedza kuzadza iripo nzvimbo dzose.

The gasi mamorekuru zvakaneta vakasungwa pamwechete, mukusiyana kune mamorekuru emura uye zvinhu zvakaoma. Vakawanda mhando yayo zvisingaiti kunzwa kuburikidza pfungwa. Asi magasi mamwe maitiro, semuenzaniso, tembiricha, kumanikidzwa, arambe achirema.

arambe achirema kwavo kunowedzera sezvo kumanikidzwa kuwedzera, sezvo ivo richikura apo tembiricha inowedzerawo. The lightest gasi ndiyo rehydrogen, rinorema - uranium exchange hexafluoride. Magasi nguva dzose yakavhenganiswa. Kana uchishanda simba regiravhiti, musanganiswa vakava heterogeneous. Easy akasimudza rinorema, nekusiyana kuburuka.

The lightest magasi - ndiko:

• rehydrogen;
• senitrogen;
• okisijeni;
• methane;
• carbon dioxide.

The nhatu dzokutanga anoreva razero boka periodic table, uye kutaura nezvazvo pazasi.

rehydrogen

Ndeupi gasi ndiyo lightest? Mhinduro iri pachena - rehydrogen. Ndiyo chinhu periodic table, inova 14.4 nguva vakareruka kupfuura mhepo kutanga. Zvinonzi akasarudzwa netsamba H, mazita rechiLatin Hydrogenium (inoberekesa mvura). Rehydrogen ndicho chinhu chinonyanya zhinji zvose. Ndiye nhengo ruzhinji nyeredzi uye yomuchadenga nyaya.

Under kwomuzvarirwo ezvinhu, hydrogen hakukuvadzi zvachose uye asiri chepfu uye asina kunhuwa uye kuravidza ruvara. Mune mamwe mamiriro ezvinhu anogona yekudyidzana kuchinja ehupfumi. Somuenzaniso, vachisanganisa pamwe okisijeni, gasi nyore rinoputika.

Inogona mudutu Platinum, simbi, titanium, nickel uye panyaya iyi. Kubva kugarotamba yakakwirira tembiricha nayo anoenda esimbi wehurumende. Its diatomic Morekuru uye ane mukuru velocity, iyo inopa rakaisvonaka chafariz conductivity pamusoro gasi (ka7 dzakakwirira kupfuura mhepo).

On redu, rehydrogen riri kunyanya majoini. By kukosha kwayo uye kuita nemakemikari urongwa, zviri wechipiri chete oxygen. Rehydrogen huri mumhepo, chikamu mvura uye Organic zvinhu zviri masero zvipenyu.

okisijeni

Okisijeni zvinoratidzwa tsamba O (Oxygenium). Uyewo haana kwakanaka, kunaka uye ruvara pasi kwomuzvarirwo ezvinhu, uye uri mune gaseous ezvinhu. Morekuru Its anowanzodanwa dioxygen, sezvo rine maatomu maviri. Pane kwayo allotropic chimiro kana nadzurudzo - ozone gasi (O3), rine mamorekuru matatu. Hazvina zvitema uye ane vanoverengeka unhu.

Okisijeni uye rehydrogen - rakajairika uye nyore magasi Panyika. The goko nyika yedu yakawanda okisijeni, zviri vanenge 47% vayo vakawanda. In kufanana ezvinhu mumvura rine zvinopfuura 80%.

Gas chinhu chinokosha muupenyu zvinomera, mhuka, vanhu uye tusingaoneki zhinji. In mumuviri womunhu chinowedzera oxidation-rutapudzo siyana, vanopinda mapapu edu mhepo.

Nokuda dzinokosha ehupfumi okisijeni, rinoshandiswa chaizvo somushonga zvinangwa. Uchibatsirwa kwayo achabvisa hypoxia, gastrointestinal chirwere, Árbol asima kurwiswa. In zvokudya indasitiri rinoshandiswa senzira kavha gasi. Mune zvokurima, yakachena kushandiswa huchiita mvura hove maberekero.

senitrogen

Kufanana yapfuura maviri gasi, inoitwa senitrogen maatomu maviri, haana raidudzwa kuravira, ruvara uye kwakanaka. Symbol kunan'anura nayo - Latin tsamba N. Panguva phosphorus uye Arsenic ndeye subgroup pniktogenov. Gas riri inert chaizvo, nokuti raakanga apiwa zita azote, iyo anoshandura kubva French se "upenyu". Nitrogenium Latin zita, rinoreva "achisununguka nitrate."

Nitrogen huri nucleic acids, chlorophyll, Chizenga uye mapuroteni chikuru chezvinonhuwira mhepo. kugutsikana Its panyika nechepasi manyowa uye masayendisiti akawanda kutsanangura kuputika kwemakomo vaitakure kubva Wepasi nejasi. In zvakasikwa gasi aripo neptunium, uye uranium exchange, chikamu zuva ezvinhu, uye vamwe yomuchadenga nzvimbo nebulae.

Man anoshandisa Nitrogen kunonyanya iri mvura. It rinoshandiswa cryotherapy, sezvo svikiro nokuda kavha uye kuchengetera zvigadzirwa. It anonzi inonyatsobudirira kurwa moto, oxygen nokunyima "potpitki" moto. Zvisinei, anoumba pamwe nesilicon Ceramics. Nitrogen inowanzoshandiswa nokuda kwetunhu siyana yeimwe, semuenzaniso, dhayi, amoniya zvinoputika.

mhedziso

Ndeupi gasi ndiyo nyore? Uye ikozvino munoziva mhinduro. Vaiona nyore sehydrogen, senitrogen uye okisijeni, chokuita razero boka periodic hurongwa. Pashure izvi vanotevera methane (kabhoni + rehydrogen) uye kabhoni oxide (kabhoni + yakachena).
