Yog li, cov nyiaj hauv carbon disulfide tsis yog ionic vim nws qhov tsis muaj zog thiab tsis tshua muaj polarity. Hloov chaw, cov ntawv cog lus hauv carbon disulfide yog covalentvim qhov sib txawv me ntsis ntawm cov electronegativities ntawm carbon thiab sulfur.
Yuav ua li cas cov compound yog carbon diselenide?
Carbon diselenide yog ib qho inorganic compound nrog cov tshuaj formula CSe2 Nws yog cov kua daj-txiv kab ntxwv oily kua nrog pungent tsw. Nws yog selenium analogue ntawm carbon disulfide (CS2). Lub teeb-sensitive compound yog insoluble nyob rau hauv dej thiab soluble nyob rau hauv organic solvents.
CSe2 yog dab tsi?
Kauj Ruam 4: Hom kev sib koom ua ke hauv carbon diselenide (CSe2) molecule - Nws yog ib ob daim ntawv cog lus ntawm txhua seleniumthiab carbon atom teeb.
Puas CSe2 muaj daim ntawv cog lus ionic?
Ob lub ntsiab tsis yog hlau. Yog li ntawd, lawv yuav tsim ib daim ntawv cog lus covalent bond.
Puas yog carbon diselenide polar lossis tsis polar?
CS2 (Carbon disulfide) yog nonpolar vim nws qhov sib luag (linear) duab.
Pom zoo:
Puas yog potassium dichromate ionic lossis covalent?
Potassium Dichromate molecules feature ob ionic bonds ntawm ob qhov txiaj ntsig zoo poov tshuaj cations thiab dichromate anion, uas tuav tus nqi ntawm -2. Lub dichromate ion nta ob lub chromium atoms uas txuas rau plaub qhov sib txawv ntawm cov pa atoms .
Puas yog ammonium sulfate ionic lossis covalent?
Ammonium Sulfate yog ib qho ionic compoundtsim los ntawm ob polyatomic ions, Ammonium N H 4+ thiab Sulfate S O 4-. Formula rau Ammonium Sulfate (NH4) 2SO4 yog tsim los ntawm kev noj ib qho hluav taws xob los ntawm ammonium kom sib npaug cov sulphate ions.
Puas muaj cov qauv crystalline ionic lossis covalent?
Ionic crystals yog tsim los ntawm kev sib hloov zoo thiab tsis zoo ions. Cov xim hlau muaj xws li hlau cations ncig los ntawm "hiav txwv" ntawm mobile valence electrons. Covalent crystals yog tsim los ntawm atoms uas yog covalently bonded rau ib leeg.
Puas yog caco3 ionic lossis covalent?
Calcium carbonate (CaCO 3 ) muaj ionic bonding ionic bonding Ib daim ntawv cog lus ionic yog lub zog hluav taws xob uas tuav ions ua ke hauv ib qho ionic compound. Lub zog ntawm daim ntawv cog lus ionic yog ncaj qha nyob ntawm seb muaj pes tsawg tus nqi thiab inversely nyob ntawm qhov kev ncua deb ntawm cov khoom them.
Puas tsis yog electrolytes ionic lossis covalent?
Nonelectrolytes yog cov tebchaw uas tsis ionize txhua hauv cov tshuaj. Yog li ntawd, cov kev daws teeb meem uas muaj cov nonelectrolytes yuav tsis ua hluav taws xob. Feem ntau, cov nonelectrolytes feem ntau yog tuav ua ke los ntawm covalent ntau dua li ionic bonds ionic bonds Ionic bonds form thaum nonmetal thiab hlau pauv electrons, thaum covalent bonds daim ntawv thaum electrons sib koom ntawm ob nonmetals.
