Ionic Hydrides
Lawv raug tsim thaum hlau uas muaj siab reactivity react nrog Hydrogen. Nws yeej muaj xws li pab pawg 1 thiab pawg 2. Lawv yeej yog binary compounds. Ntawm tag nrho cov, Lithium, Beryllium thiab Magnessium hydrides muaj tus cwj pwm covalent siab.
Ib yam li ntawd, hydrides piav nrog piv txwv li cas?
Hydrides . Hydride , hauv cov ntsiab lus yooj yim, tau hais tias yog anion ntawm hydrogen. Nws yog ib qho tshuaj sib xyaw uas cov hydrogen atoms nthuav tawm nucleophilic, yooj yim lossis txo cov khoom. Qee qhov nrov tshaj plaws piv txwv suav nrog dej (H2O), methane (CH4thiab ammonia (NH3).
Tsis tas li ntawd, hydrides cais li cas? Hydrides yog cais rau hauv peb pawg loj, nyob ntawm seb cov ntsiab lus ntawm hydrogen bonds rau. Peb pawg loj yog covalent, ionic, thiab metallic hydrides . Raws li txoj cai, hydride yog lub npe hu ua qhov tsis zoo ion ntawm hydrogen, H-, kuj hu a hydride ion.
Ib yam li ntawd, koj tuaj yeem nug, dab tsi yog hydrides thiab nws hom?
Hydride , ib chav kawm ntawm cov tshuaj sib xyaw ua ke uas hydrogen ua ke nrog lwm lub ntsiab lus. Peb qhov yooj yim hom ntawm hydrides -saline (ionic), nws yog xim hlau, thiab covalent - tej zaum yuav txawv ntawm lub hauv paus ntawm hom ntawm chemical bond koom nrog.
Cov pab pawg twg tsis tsim hydrides?
Nws muaj yuav tsum tau muab sau tias cov ntsiab lus ntawm pab pawg 7, 8, 9 ntawm d-block tsis tsim hydrides tag nrho. Qhov no tsis muaj peev xwm ntawm hlau, ntawm pab pawg 7, 8, 9 ntawm periodic table tsim hydrides yog hu ua hydride qhov sib txawv ntawm d-block. Nyob rau hauv cov tebchaw H atoms yuav tsum nyob interstitial txoj hauj lwm nyob rau hauv cov hlau lattices.

Dab tsi yog hydrides muab lawv cov kev faib tawm?
Hydrides tau muab faib ua peb pawg loj, nyob ntawm seb cov ntsiab lus ntawm hydrogen bonds rau. Peb pawg loj yog covalent, ionic, thiab metallic hydrides. Raws li txoj cai, hydride hu ua qhov tsis zoo ion ntawm hydrogen, H-, kuj hu ua hydride ion
Canal rays Class 9 Ncert yog dab tsi?
Teb: Canal rays yog cov hluav taws xob muaj txiaj ntsig zoo uas coj mus rau qhov kev tshawb pom ntawm qhov muaj txiaj ntsig zoo sub-atomic particle hu ua proton
Dab tsi yog Class A explosives?
Class A Explosives - ib lo lus uas yav tas los siv los ntawm US Department of Transportation los piav txog cov khoom tawg uas muaj detonating lossis lwm yam kev phom sij tshaj plaws. (Tam sim no muab faib ua Division 1.1 lossis 1.2 cov ntaub ntawv.)
Cov nroj tsuag tropism Class 10 yog dab tsi?
Lub tropism yog kev loj hlob mus rau lossis deb ntawm astimulus. Cov stimuli uas cuam tshuam cov nroj tsuag loj hlob muaj xws li lub teeb, lub ntiajteb txawj nqus, dej, thiab kov. Cog tropisms txawv los ntawm lwm yam stimulus generated txav, xws li nastic taw, nyob rau hauv hais tias cov kev taw qhia ntawm cov lus teb nyob ntawm seb cov kev taw qhia ntawm lub stimulus
Periodicity Class 10 yog dab tsi?
Kev rov ua dua ntawm cov khoom tom qab ib ntus yog hu ua periodicity ntawm cov khoom. Yog hais tias cov ntsiab lus tau teem rau hauv qhov kev txiav txim ntawm lawv cov atomic naj npawb hauv lub sij hawm, ces cov ntsiab lus rov qab nws cov khoom tom qab lub sij hawm meej. Qhov kev rov ua dua ntawm cov khoom no yog hu ua periodicity ntawm cov khoom
