Hydrogen

Hydrogen ua hoʻomano hoʻohana 'ia i loko o kekahi mau lala o ka hana: i loko o ka hoʻololi kemikala o ka hydrogen koloriside, ammonia (ammonia ua hou hoʻohana no ka? Iecaianoaaiiie o ka naikokene fertilizers), i loko o ka hana o ka aniline, ma o ka loaa o ka ole-ferrous metala i eliia. Ma ka meaʻai hana ka mea, ua hoʻohana 'ia e paka ae pani ai no ka holoholona momona (margarine). I e pili ana me ka luna pili pukana o ka? Iecaianoaaiiie o ka hydrogen ma ka hanalima 'ia.

He kinoea ua noʻonoʻo me ka ikehu lawe i loko o ka wā e hiki mai no ka mea, o ka pāhana, 'aʻole i hoʻokuʻu akula "kinoea hoʻomehana honua" CO₂ i'ā, produces he nui nui o ka ikaika no pa alima kaumaha i loko o ka'ā kaʻina hana, a ua hiki wawe ka hoohuliia i loko o uila mana o ka wahie aeea.

Ma lalo o keʻena hoʻokolohua kumu hydrogen pinepine loaa ma ka hoemi i eliiaʻi a pau i koe ma ka electrochemical anakahi uila puke, mai ka wai a me nāʻakika:
Zn + 1HCl = ZnCl₂ + H₂ ↑: ΔH <0
2Na + 2HOH = 2NaOH + H₂ ↑: ΔH <0.

I hana, hydrogen loaa ia lŘlŘʻano nui e maoli aaioee a pili kinoea.

1. ka methane huli ana. Ke kaʻina ninoieo ma ka naoh o methane me ka wai ohu i 800 - 900 ° C: CH₄ + H₂O = CO ↑ + 3H₂ ↑; ΔH> 0. A me kēia kaʻina ka hoʻohana hapa'okesaside o hydrocarbons me ka o oxygen ma ke alo o ka wai mahu: 3CH₄ + O₂ + H₂O = 3CO + 7 H₄. Kēia mau kiʻina hana e ho'ōla lilo aku i ko lakou nui me hydrocarbon me ke koe i depleted.

2. Biohydrogen hiki ke loaa mai ka līoho i loko o ka bioreactor. Ma ka hopena o 1990s ka mea i loaʻa i ina luaipele hoonele līoho, e OIeEOEIeAeEIIe ka mea, mai ka-i? Iecaianoaaiiuo o ka oxygen, oa. E. Normal kāʻamaʻai, i ka hydrogen? Iecaianoaaiiie. Biohydrogen i hiki ke hua mai i loko o bioreactors, ka hoʻohana 'ana, koe wale no ka līoho, kulanakauhale neoneo. Ke kaʻina ia lŘlŘ ma koʻohune i omoʻia hydrocarbon, a paka hydrogen a me ka CO2.

3. Deep anuanu maila 'o Coke umu kinoea. Ma ke kaʻina hana o ka coking lanahu hoomakaukau ekolu mahele: he paa - Coke, wai - lanahu hohono - a he kinoea i loaʻa, a keu aku hydrocarbons, hakakino hydrogen (ma kahi o 60%). Keia hapa Ua malalo i kaʻoi loa hohonu ka huʻihuʻiʻana ma hope o ka ia me ka kūikawā mea, aʻo ka mea e hiki ai, e hoʻokaʻawale hydrogen mai impurities.

4.? Iecaianoaaiiuo o ka hydrogen, mai ka wai hoʻohana electrolysis - he iaoia e haawi i ka clearest hydrogen: 2H₂O → electrolysis → 2H₂ + O.

5. E ka o carbon huli ana. Initially, ka wai kinoea ua loaa ia ma ka hele i ka wai ohu ma ka ula-wela i ka 1000 ° C Coke: C + H₂O = CO ↑ + H₂ ↑; ΔH> 0, i laila, i hui pūʻia me ka mahu ua hele akula ma kēlā wela i ka 400 - 500 ° C hōʻeleu Fe₂O₃. Ke AaOIeIOUIeXAOAaIN o kalapona monoxide (II) a me ka mahu: CO + H₂O + (H₂) = CO₂ + 2H₂ ↑; ΔH> 0.

6.? Iecaianoaaiiuo o ka hydrogen ma ka huli ana o ke kalapona monoxide (CO), ma muli o kekahi hanana naoh ma ka ulaula photosynthetic koʻohune (unicellular microorganisms palapala ulaula paha a pink kala like 'ole, a ua pili i ke alo o ka photosynthetic pigments). Mau koʻohune paka hydrogen ma ka naeaeaa naoh: CO + H₂O → CO₂ + H₂.

Ke kahua o ka hydrogen ka wai, i ka naoh aʻole i koi kiʻekiʻe ana wela a me kau iho. Ke kaʻina hana i wahi ma ka lumi ana wela i loko o ka pouli.

Hanalima nui kēia manawa ka loaʻa iā ia kekahi o ka evolution o hydrogen, mai na kinoea hua mai la iʻaila kā hoohehee maemae au ia.

Eia naʻe, he nui mai i ike i ka mea i hiki ke loaa ka hydrogen ma ka hale. No keia mea, ua hiki ke hoʻohana i ka naoh pāʻoihana o ka mekala 'åkilikai a me ka Aluminum. E hapa-hano aniani hue i ka pani puka, i ka mahu şarkı, 10 g. O ke keleawe sulufahate, 20 g. Paakai, 10 g. O ka alumina, 200 g. O ka wai hoʻonui.

E hoomakaukau oukou i ka pāʻoihana o ke keleawe sulufahate: 100 g. O ka wai i hoʻohuiʻia 10 g. O ke keleawe sulufahate.

Sayings ka paʻakai pāʻoihana: 100 g. O ka wai i hoʻohuiʻia 20 g. O ka paakai.

Ke kākoʻo pāʻoihana Ua hui. Pākuʻi i ka kūpono hui o Aluminum. Once i loko o ka hue ikea keʻokeʻo slurry paʻa i ka Tube a me ka hoʻonui hoʻopiha ia me ka Hawaiʻi hydrogen.

E lohe! Kēia ka hoao ana wale Pono e pana aku au i ke ao o waho. Koi welaʻana mai, mai ka naoh i wahi me ka evolution o ka wela, a hiki ke kiʻi mai o ke ana.

Ia e hoomanao ai no hoi ia hydrogen, ina ka mea, ua hui ia me ka lewa, ano pahū ukuhiia, i ua kapaia detonating kinoea (nā māhele hydrogen a me kekahi hapa ka oxygen). Inā keia läÿau, e ignite, ka mea e explode.
