2024 Tus sau: Miles Stephen | [email protected]. Kawg hloov kho: 2023-12-15 23:36
Cov thawj kauj ruam yog los tshuaj xyuas qee qhov kev cai yooj yim thiab tom qab ntawd ua haujlwm los ntawm cov pab pawg ua haujlwm, maj mam tsim cov kev txawj uas yuav tsum tau ua.
Ib yam li ntawd, koj ua li cas Iupac nomenclature?
IUPAC Cov Cai rau Alkane Nomenclature
- Nrhiav thiab npe cov kab txuas txuas txuas ntev tshaj plaws.
- Txheeb xyuas thiab npe cov pab pawg uas txuas nrog cov saw no.
- Tus lej ntawm cov saw sib txuas ua ke, pib ntawm qhov kawg ze tshaj ib pab pawg hloov pauv.
- Tsim qhov chaw ntawm txhua pab pawg neeg hloov pauv los ntawm tus lej tsim nyog thiab lub npe.
Tsis tas li ntawd, dab tsi yog qhov tseem ceeb nomenclature? Cov pab pawg ua haujlwm nrog lub siab tshaj plaws qhov tseem ceeb yuav yog tus uas muab nws lub ntsiab lus rau lub npe ntawm lub molecule. Yog li hauv qhov piv txwv # 1 saum toj no, cov lus kawg ntawm cov molecule yuav yog "-oic acid", tsis yog "-ib", vim tias carboxylic acids tau muab siab dua. qhov tseem ceeb.
Tom qab ntawd, lo lus nug yog, ua li cas koj lub npe organic tebchaw kauj ruam yog kauj ruam?
Compound naming kauj ruam
- Kauj Ruam 1: Nrhiav qhov ntev tshaj plaws carbon saw nyob rau hauv peb lub compound. Peb yuav siv qhov sib xyaw no ua peb tus piv txwv rau npe.
- Kauj Ruam 2: Lub npe uas ntev tshaj plaws carbon saw.
- Kauj Ruam 3: Txheeb xyuas qhov xaus (suffix) yuav tsum yog dab tsi.
- Kauj Ruam 4: Sau koj cov carbon atoms.
- Kauj Ruam 5: Sau npe cov pab pawg sab.
Lub nplhaib 5 carbon hu ua dab tsi?
Feem ntau nplhaib compounds muaj xws li 5 lub 6 carbon. Cov tebchaw no kuj yog hu ua cyclic. Cyclopentane: Txawm hais tias qhov kev sawv cev yooj yim tshaj plaws yog cov kab kos ntawm lub pentagon raws li qhia rau sab laug.

Thawj kauj ruam hauv kev sau ntawv yog dab tsi?
Thawj kauj ruam ntawm kev sau ntawv yog hu ua pre-initiation. RNA polymerase thiab cofactors (generaltranscription yam) khi rau DNA thiab unwind nws, tsim ib tug pib npuas. Qhov chaw no muab RNA polymerase nkag mus rau asingle strand ntawm DNA molecule
Dab tsi yog thawj kauj ruam hauv cov saw hlau thauj electron?
Cov saw hlau thauj khoom siv hluav taws xob siv cov khoom lag luam los ntawm thawj ob txoj haujlwm ntawm glycolysis thiab citric acid voj voog kom tiav cov tshuaj tiv thaiv uas hloov peb cov zaub mov rau hauv lub zog siv tau ntawm tes
Dab tsi yog cov kauj ruam los daws qhov tsis sib xws ntawm ob kauj ruam?
Nws yuav siv ob kauj ruam los daws qhov kev sib npaug lossis qhov tsis sib xws uas muaj ntau tshaj ib qho kev ua haujlwm: Simplify siv qhov sib txawv ntawm qhov sib ntxiv lossis rho tawm. Ua kom yooj yim ntxiv los ntawm kev siv qhov sib txawv ntawm qhov sib npaug lossis faib
Cov kauj ruam ntawm mitosis yog dab tsi thiab dab tsi tshwm sim hauv txhua qhov?
Mitosis muaj tsib theem sib txawv: interphase, prophase, metaphase, anaphase thiab telophase. Cov txheej txheem ntawm cell faib tsuas yog ua tiav tom qab cytokinesis, uas tshwm sim thaum lub sij hawm anaphase thiab telophase. Txhua theem ntawm mitosis yog tsim nyog rau cell replication thiab faib
Koj ua li cas electron configuration kauj ruam yog kauj ruam?
Cov kauj ruam Nrhiav koj tus lej atomic. Txiav txim siab tus nqi ntawm lub atom. Nco cov npe ntawm cov orbitals. Nkag siab txog kev teeb tsa hluav taws xob. Nco qhov kev txiav txim ntawm lub orbitals. Sau rau hauv lub orbitals raws li tus naj npawb ntawm electrons hauv koj lub atom. Siv lub sij hawm ntev raws li qhov pom kev luv luv
