Kuj nug, puas yog co3 2 muaj cov qauv resonance?

Txij li thaum carbon yog nyob rau hauv lub sij hawm 2 nws ua tsis yog muaj nkag mus rau d sublevel thiab yuav tsum ua raws li txoj cai octet. Muaj peb yam sib txawv resonance qauv los ntawm carbonate. Txhua cov pa roj carbon monoxide tuaj yeem xav tias yog 1.333 daim ntawv cog lus. qhov nruab nrab ntawm ob daim ntawv cog lus thiab 2 ib daim ntawv cog lus.

Kuj Paub, muaj pes tsawg electrons puas co3 2? CO3 ^ 2 - yog hu ua carbonate ion. Ua ntej peb xav tau suav tag nrho cov valence electrons . Peb tsuas ntxiv qhov valence electrons ntawm txhua lub atoms koom nrog.qhov no nws yog qhov tsis zoo 2 yog li peb ntxiv ob electrons.

Qhov thib ob, muaj pes tsawg tus qauv Lewis ua co32?

Yog li ntawd nws yog muab tso rau hauv qhov chaw ntawm lub dotstructure . Rau qhov CO32 - Lewis qauv nyob ntawd yog tag nrho ntawm 24 valence electrons muaj.

Dab tsi yog qhov molecular geometry ntawm co3 2?

Electron repulsion raug txo qis thaum 3 oxygen atoms nyob ntawm cov ces kaum ntawm daim duab peb sab sib npaug. Yog li ntawd, CO32-ion muaj trigonal-planar puab , ib yam li BF3, nrog lub kaum sab xis ntawm 120 degree. Lewis qauv yog dab tsi CO32 -?

Pom zoo:

Muaj pes tsawg guanine bases puas yog 50 lub hauv paus khub ob txoj hlua DNA 100 bases tag nrho muaj yog tias nws muaj 25 adenine bases?

Yog li, muaj tag nrho ntawm 25 + 25 = 50 adenine thiab thymine hauv tag nrho. Qhov ntawd tawm 100− 50 = 50 seem hauv paus. Nco ntsoov tias cytosine thiab guanine daim ntawv cog lus nrog ib leeg, thiab yog li lawv sib npaug ntawm cov nyiaj. Tam sim no peb tuaj yeem faib los ntawm 2 kom tau txais tus lej ntawm guanine lossis cytosine hauv paus

Muaj pes tsawg atoms al2 co3 3 muaj?

Cov feem pua ntawm cov ntsiab lus Element Cim # ntawm Atoms Aluminium Al 2 Carbon C 3 Oxygen O 9

Muaj pes tsawg qhov kev zam rau tus qauv electron configurations muaj nyob rau hauv D block?

ob Ntawm no, cov ntsiab lus twg yog kev zam rau Aufbau txoj cai? Piv txwv li, ruthenium, rhodium, nyiaj thiab platinum yog tag nrho kev zam rau Aufbau txoj cai vim yog sau los yog ib nrab puv subshells. Ib sab saum toj no, yog vim li cas electron configuration rau tooj liab 1s22s22p63s23p63d104s1 es tsis txhob 1s22s22p63s23p63d94s2?

Tus qauv qauv yog dab tsi Qhov txawv ntawm tus qauv qauv thiab tus qauv molecular yog dab tsi?

Cov mis mos molecular siv cov cim tshuaj thiab cov ntawv sau npe los qhia cov naj npawb ntawm cov atoms sib txawv hauv cov molecule lossis compound. Ib qho empirical formula muab qhov yooj yim tshaj plaws, tag nrho tus lej piv ntawm atoms hauv ib qho chaw. Cov qauv qauv qhia txog kev sib koom ua ke ntawm cov atoms hauv cov molecule
