Hydrides - Ko ... hydrides Taupānga

fehangahangai takitaha o tatou kei te ki te ariā o tenei pūtaiao, rite matū. I te tahi taime e na rite e he reira uaua ki te wehewehe tetahi i tetahi ratou. Ko he mea nui ki te mahino katoa o ratou, no te mea arata'i ētahi wā he pōhēhē ki te āhuatanga rawa Eparima, a ētahi wā ki te hapa ore. I roto i tēnei tuhinga ka aparau i tatou ki ta hydrides, e te hunga kino, me te e kore e, te wahi e whakamahia ratou me pehea e whiwhi. Ko tīmata tatou ki te haerenga poto ki hītori.

kōrero

tīmata tana kōrero ki te hauwai hydrides kitea. Tenei huānga i roto i te rau tau 18 kitea Henry Cavendish. mohiotia hauwai te ki kia whakaurua i roto i te hanganga o te wai , me te ko te pūtake mo te tahi atu āhuatanga katoa o te ripanga pūmotu. Ngā mihi ki a ia, te oraraa o taea pūhui waro, me te ora i runga i to tatou paraneta.

I tua atu, hauwai ko te pūtake mo te maha pūhui pararopi. Ēnei ngā waikawa me turanga, me te ahurei pūhui hauwai-rua ki te tahi atu āhuatanga - hydrides. e kore e mohiotia ïa te rā o ratou kōtuitanga tuatahi, engari kua hydrides kore-konganuku mohiotia ki te tangata mai i nga wa onamata atu. Ko te noa tino o ratou - te wai. Ae, te wai - ko reira he hydride o te hāora.

Ano i roto i tenei piha ngā haukini (wähanga matua o te haukini), hauwai sulfide, hauwai pūhaumāota, me te rite. Mō ētahi atu pārongo e pā ana ki te āhuatanga o ngā matū i tenei piha kanorau, me te faahiahia o pūhui ka kia kōrero i roto i te wāhanga o muri.

ngā āhuatanga ōkiko

Hydrides - Ko te nuinga hau. Heoi, ki te tango tatou i te hydrides whakarewa (he kotiti i roto i ngā āhuatanga noa ratou, ka ariu rawa tere ki te wai), kia waiho ai totoka. Etahi o ratou (hei tauira, hauwai pūkeha) tīariari i roto i te āhua wai.

He whakaahuatanga whānui o te taua piha nui o matū ko e taea noa, no te mea he rerekē katoa ratou, ka, ki runga ki te tūemi, i te mea wahi o hydride rānei, i roto i te tua ki te hauwai, whai āhuatanga tinana rerekē, me ngā āhuatanga matū. Ko taea te wehea ratou ki akomanga, te pūhui i roto i nei te tahi mea rite. Kei raro whakaaro tatou motuhake piha ia.

hydrides katote - he hauwai pūhui ki konganuku whenua alkali kawakore ranei. tohu ratou he kainga ma totoka, i raro i ngā āhuatanga noa. Ki runga ki whakawera, e decomposed enei pūhui ki to ratou whakarewa wāhanga, me te hauwai, kahore rewa. Ko tētahi okotahi - ko LiH, e rewa kahore whāwehe me tahuri whakawera kaha ki Li ko H _2.

hydrides Metal - he pūhui whakawhitinga whakarewa. Tino maha to ratou he hanganga tāupe. Ka taea e ratou kia hakari rite otinga mārō o hauwai i roto i te whakarewa. A hoki to ratou he hanganga karaihe o te whakarewa.

Na roto i te hydrides kotuari no ki noa te ahua e ko te nuinga noa i runga i te whenua: pūhui hauwai ki-konukore. tohatoha Whānui rohe o enei matū e tika ana ki to ratou pūmautanga teitei, ko te kaha o te matū rite kotuari here.

Ka rite ki te hydride tātai tauira, silicon: SiH _4. Ki te titiro koe ki taua mea i roto i te rōrahi, kitea tatou e toia hauwai rawa raru ki te ngota silicon pokapū me ona irahiko ano wāhikē tukunga. He Silicon he electronegativity makona nui, Na, e taea o kaha kukume irahiko ki tona matua, reira whakaiti i te roa here ki waenganui reira me te ngota pātata. A, kia rite ki matau koutou, te poto te hononga, na ko reira kaha.

Ka aparau i te wāhanga e whai ake nei i te rerekētanga i waenganui i te hydrides i te tahi atu pūhui i roto i ngā o te tauhohenga matū.

āhuatanga matū

Ko te hoki tenei wāhanga hydrides utu wehea ki te taua rōpū rite i roto i te mua. A ka tīmata tatou ki nga āhuatanga o hydrides katote. Ko te rerekētanga matua i te tahi atu momo e rua i roto i taua ratou kaha taunekeneke ki te wai ki te hanga i hauwai me te tuku alkali te hau. Ko te tino taikaha wai, na te tino maha penapena te hononga ki te whakarerenga o te houku - Hydride tauhohenga. Ko tenei no te mea kei te ara i roto i te wai i roto i te rangi e taea te tīmata te hurihanga mōrearea.

whakaatu tatou i te whārite tauhohenga i runga i roto i te tauira o taua matū rite pāhare pāporo hydride:

KH + H ₂ E = KOH + H ₂

Ka rite ki taea e matou te titiro, he tino ohie mea katoa. Na reira, whakaaro tatou atu ngā tauhohe āhuatanga o te tahi atu momo e rua whakaahuatia tatou matū.

I roto i te parau tumu, te tahi atu panoni e kore e i tangohia tatou motu, āhuatanga o ngā momo katoa o matū. ahu ratou ki te tauhohe ki waikura konganuku, konganuku hanga, ranei ki te wai waihā ranei (te whakamutunga, ko te āhuatanga o te kawakore me kawakore-whenua konganuku).

Ko tētahi atu tauhohenga ngā - ngāwhā whāwehe. puta te reira i pāmahana tiketike, me te toro ki te hanganga o te whakarewa me te hauwai. E kore matou e noho i runga i tenei tauhohenga, rite reira kua kua oti tātarihia i roto i te wāhanga o mua.

Ko te kupu, uiuia maua nga āhuatanga o tenei momo o pūhui ā-rua. Na ko reira tika ki te kōrero e pā ana ki to ratou faaineineraa.

whiwhi hydrides

Tata ki te katoa o hydrides kotuari - he pūhui tūturu. E tino pūmau ana ratou, na e kore e hinga ki raro i te mana o ope waho. Ki te katote me whakarewa hydrides mea katoa, he iti ake uaua. e kore e ratou te tīariari i roto i te natura, na to ratou ki te kia synthesized. mahi tēnei rawa noa: na roto i te tauhohe i hauwai me te huānga pāhekoheko e hiahiatia ana e te ki te farii i hydride.

tono

e kore e ētahi hydrides whai tono ngā, engari te nuinga - he tino nui hoki te āpiha ahumahi. E kore matou e haere ki kōrero, no te mea i rongo e nga tangata e, mo te tauira, whakamahia haukini kei roto i ngā wāhi maha, a ko te rauemi mahuinga ia mo te hanga o waikawa amino tāwhaiwhai me ngā pūhui matū waro. Ko te whakamahi o hydrides maha he iti ki te āhuatanga o ratou āhuatanga matū. Na reira, kei te whakamahia ratou anake i roto i ngā taiwhanga.

Taupānga - wāhanga whānui rawa hoki tenei piha haapiiraa o matū, na i iti matou ki meka whānui. Ko te wahi i muri e korero ki a koe e hia o tatou, e kore he mohio tika, whakapoauau kinokore (ranei i te iti rawa mohiotia) mea i waenganui ia ratou.

tahi mau mana'o hape

Hei tauira, whakapono etahi e te hauwai hydride - te tahi mea kino. Ki te taea te karanga e koe i te reira taonga, na kahore tetahi e. Ki te whakaaro tatou, hauwai hydride - he hauwai pūhui ki hauwai, a konei - H ₂ rāpoi ngota. O te akoranga, tenei hau kino, engari anake i roto i te ranunga ki te hāora. I roto i tona puka parakore e kore he reira mōrearea.

He he he rota o taitara kerekere. heke ratou ki te tangata rerekē wehi. Heoi, ka rite ki whakaaturanga mahi, te nuinga o ratou he kinokore, me te whakamahia mō ngā take kāinga.

mutunga

he nui Matū World, a ka whakaaro matou e, ki te kahore i muri i tenei, i muri i te maha atu tuhinga, ka kite koutou i hoki koe. Ko te aha hanga reira tikanga ki te kia rumakina i roto i tona ako ki tona matenga. kua whakatuwheratia Humanity te rota o hou, me te noa atu tonu unknown. A, ki te ite koe e kahore he mea ngā i roto i te mara o hydrides, he nui atu to koutou.
