Chii chinonzi Calcium hydride

Calcium hydride ikemikari ine fomula CaH2. Ichena, crystalline yakasimba iyo inoshanda zvakanyanya uye inowanzoshandiswa sechinhu chinoomesa muorganic synthesis. Mushonga wacho unoumbwa nekarusiyamu, simbi, uye hydride, ioni yehydrogen ion yakashata. Calcium hydride inozivikanwa nekugona kwayo kuita nemvura kugadzira hydrogen gasi, ichiita kuti ive reagent inobatsira mukuita kwakasiyana kwemakemikari.

Chimwe chezvinhu zvakakosha zve calcium hydride kugona kwayo kutora unyoro kubva mumhepo. Izvi zvinoita kuti ive inoshanda desiccant, kana kuomesa mumiriri, murabhoritari uye maindasitiri. Kana yaiswa kune unyoro, calcium hydride inopindirana nemvura kuita calcium hydroxide uye hydrogen gasi. Kuita uku kunoburitsa kupisa uye kunobatsira kubvisa mvura kubva munzvimbo yakapoteredza, zvichiita kuti ibatsire pakuomesa zvinonyungudutsa nezvimwe zvinhu.

Pamusoro pekushandiswa kwayo sechinhu chekuomesa, calcium hydride inoshandiswawo mukugadzirwa kwehydrogen gasi. Kana calcium hydride ikabatwa nemvura, inosangana nekemikari inoburitsa gasi rehydrogen. Iyi nzira, inozivikanwa sehydrolysis, inzira iri nyore yekugadzira haidhirojeni murabhoritari. Iyo hydrogen gasi inogadzirwa inogona kushandiswa mumhando dzakasiyana dzekushandisa, kusanganisira masero emafuta uye sechinhu chinodzikisa mukuita kwemakemikari.

Calcium hydride inoshandiswawo mukugadzirwa kweorganic compounds. Kugona kwayo kubvisa mvura kubva musanganiswa wekuita kunoita kuti ive chinhu chakakosha mumakemikari organic. Nekushandisa calcium hydride sechinhu chinoomesa, vemakemikari vanogona kuona kuti maitiro avo anoenderera pasi peanhydrous mamiriro, izvo zvinowanzokosha pakubudirira kwemamwe maitiro.

Mukupedzisa, calcium hydride isanganiswa inoenderana neyakasiyana-siyana yakakosha mashandisirwo mumakemikari. Kugona kwayo kutora hunyoro uye kuburitsa hydrogen gasi inoita kuti ive chishandiso chakakosha kune vanotsvaga uye maindasitiri emakemikari zvakafanana. Kunyangwe ichishandiswa sechinhu chinoomesa, chitubu chehydrogen gasi, kana reagent mune organic synthesis, calcium hydride inoita basa rakakosha mumunda wekemikari.
