Toka Te Manawa

• Tauira o hydrides
• Whakamahinga hydrides

Ko tehydrides He kohinga matū enei e whakakao ana i nga ngota hauwai i roto i a raatau ngota ngota (ko te ahua o te waikura he, i te nuinga o te waa, -1) me nga ngota o etahi atu waahanga o te teepu haurua.

E toru nga waahanga hydrides e mohiotia ana:

• Konganuku konganuku: Ko era o nga mea i hangaia me nga mea kawakore me te waikawa-whenua, ara, me era e neke atu ana ki te taha maui o te tepu waahi o nga waahanga. He huinga kore-koretake e whakaatu ana i te kawe. Ko te hauwai e kitea ana i roto i a ratau ko te katote hydride H.. I roto i tenei roopu ka taea te wehewehe i nga hydrides e hanga ana i nga konganuku hiko (mai i te roopu 1 me te 2); ko enei hydrides e kiia ana he hydrides tote. Ko te waikawa saline he ma ma, he kirikiri hina ranei na te urupare tika o te whakarewa me te hauwai i nga wera nui.
• He waikore, he kore-konganuku ranei hydrides:ko era e hangaia ana me nga waahanga kore-konganuku engari he iti noa te hiko, ina koa, me te hauota, te phosphoror, te arsenic, te antimony, te bismuth, te boron, te waro me te silicon: he ingoa motuhake enei katoa, kei tua atu i te ingoa ingoa whanui; he konganuku katoa, he konganuku ranei no te p poraka. Ka taea hoki te karanga ko te waikura ngota ngota ranei, na te mea he hononga taapiri. Ka hangaia he kohuke o etahi tino waahanga. Ko Silane, he hydride i roto i tenei roopu, kei te piki haere tona hiahia mo tona uara ki te hanga nanoparticles.
• Hydrogen hydrides:(e kiia ana ko te hydracids noa) e pa ana ki te whakakotahi o te hauwai me te haukini (fluorine, chlorine, bromine me iodine ranei) me te waahanga antigenic (oxygen, sulfur, selenium, Tellurium); anake i te keehi o muri ka mahi te hauwai me tona tau haurangi pai (+1) me tetahi atu waahanga ko te mea e mahi ana me te tau waikura kino (-1 i nga halogens, -2 i nga amphogens).

Whakamahinga hydrides

I roto i nga whakamahinga o te hydrides ka taea e taatau te whakahua i era o Tuhinga ka whai mai, ko etahi e whakamahia ana hei puna hauwai parakore.

He pai te waikawa konupūmā hei kaihoko whakamaroke whakarewa organic. Me tino tupato te whakahaere o te Sodium hydride, na te mea ka kaha te aro ki te wai ka taea te mura.

Mena ka puta he ahi na te mura o tenei hydride, kaua e whakamahia te wai hei tinei, na te mea ka mate ka nui ake te mura o te ahi. Ka mate enei ahi kaipatu ahi puehu.
