Cov ntsiab lus ntawm kev txaus siab hauv caffeine rau ib leeg khub yog nitrogen thiab oxygen; cov pa roj carbon monoxide yuav tsis muaj ib leeg khub . Oxygen nrog ob daim ntawv cog lus thiab tag nrho octet yuav muaj ob ib leeg khub , thaum nitrogens nrog peb daim ntawv cog lus thiab tag nrho octet yuav muaj ib qho nyob ib leeg khub. Yog li ntawd, muaj 8 ib khub hauv caffeine.
Xav txog qhov no, pes tsawg electrons nyob hauv caffeine?
Caffeine muaj 10p electrons , yog li ntawd yog aromatic.
Puas yog caffeine polar lossis nonpolar compound? Yog, caffeine yog ib tug polar molecule. Raws li koj tuaj yeem pom los ntawm nws cov qauv ntawm no: Lub Oxygen thiab Nitrogen molecules muaj zog polarity dua Cov pa roj carbon , cia lawv me ntsis rub cov electrons ntawm lawv hauv lawv covalent bond.
Ib sab saum toj no, dab tsi yog hybridization ntawm caffeine?
Cov nitrogen atoms nyob rau hauv caffeine molecule yog tag nrho cov tseem ceeb planar. Txawm hais tias qee qhov feem ntau kos nrog peb ib daim ntawv cog lus, ib leeg khub ntawm cov atoms tau koom nrog hauv resonance nrog ob-bonded carbon atoms uas nyob ib sab, thiab yog li txais yuav sp2 orbital. hybridization.
Puas yog caffeine yog ib qho qauv molecule?
Caffeine yog achiral molecule tsis muaj stereoisomers. Muaj ob pawg amide ntawm caffeine . Lawv muaj nyob ua ke raws li zwitterionic resonance qauv qhov twg nitrogen thiab carbon atoms yog ob leeg sib koom ua ke kom ob leeg nitrogen atoms yog qhov tseem ceeb. kev npaj (hauv sp2 orbital hybridization).

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 tus txiv neej tsim cov ntsiab lus muaj nyob rau hauv lub rooj zaum?
Cov khoom siv hluavtaws yog cov uas muaj atomic tooj 95-118, raws li pom hauv ntshav ntawm lub rooj sib tham nrog: cov 24 lub ntsiab lus no tau tsim thawj zaug thaum xyoo 1944 thiab 2010

Cov dev muaj 39 khub ntawm chromosomes hauv lawv cov hlwb somatic. 3. Nees muaj 16 chromosomes hauv lawv cov hlwb haploid
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?
Muaj pes tsawg tus khub nyob hauv BrF5?
