Cov lus piav qhia (nrog rau kev sib npaug tshuaj tseem ceeb): Co(H2O)62+ complex yog liab, thiab CoCl42- complex yog xiav. Cov tshuaj tiv thaiv no yog endothermic raws li sau tseg, yog li ntxiv cov cua sov ua rau qhov sib npaug tsis tu ncua hloov mus rau sab xis. Qhov no, sib piv, ua rau kev daws teeb meem xiav
Lub hli yog nyob rau hauv orbit ncig lub ntiaj teb txhais tau hais tias nws yog nyob rau hauv nws lub ntiajteb txawj nqus. Txhais tau hais tias nws raug rub mus rau lub ntiaj teb nrog lub zog tas li thiab lub hli raug rub mus rau nws. Tab sis nws txav nrawm txaus uas lub ntiaj teb lub ntiajteb txawj nqus tsis muaj zog txaus los rub nws mus rau saum npoo
Cov noob yog ib ntu ntawm DNA molecule uas txiav txim siab cov qauv ntawm polypeptides (proteins) thiab yog li qhov tshwj xeeb. Qhov sib lawv liag ntawm nucleotides hauv DNA txiav txim qhov sib lawv liag ntawm cov amino acids hauv polypeptides, thiab yog li cov qauv ntawm cov proteins. Txhua tus uas yog lub luag haujlwm rau ib qho kev zoo
Rays feem ntau hu ua ob txoj kev: Los ntawm ob lub ntsiab lus. Hauv daim duab saum toj kawg nkaus ntawm nplooj ntawv, txoj kab hluav taws xob yuav raug hu ua AB vim pib ntawm point A thiab hla B ntawm nws txoj kev mus rau infinity. Los ntawm ib tsab ntawv. Cov kab hluav taws xob saum toj no yuav raug hu ua 'q'
Lub hav zoov sov sov yog qhov kub thiab noo biome qhov twg nws los nag txhua xyoo. Nws yog lub npe hu rau nws qhov ntom ntom ntawm cov nroj tsuag uas tsim peb txheej sib txawv. Lawv nce ntoo nyob rau hauv lub canopy kom ncav cuag lub hnub ci. Nruab nrab txheej, los yog understory, yog ua los ntawm vines, me me ntoo, ferns, thiab xibtes
Copper(ii) sulfate, CuSO4, feem ntau hu ua "copper sulfate", tab sis tau raug hu ua cupric sulphate, xiav vitriol (hauv daim ntawv pentahydrate), bluestone (raws li pentahydrate), chalcanthite (pentahydrate mineral), bonattite (trihydrate mineral), boothite (heptahydrate ntxhia), thiab chalcocyanite (mineral)
Acetone yog ib tug polar molecule vim ithasa polar daim ntawv cog lus, thiab cov qauv molecular tsis ua rau lub dipole yuav tsum tau muab tso tseg. Tsis muaj lwm yam dipole tshem tawm C-O dipole. Xaus: Themolecule ispolar
Ob qho! Kuv xav tias nws nyob ntawm koj lub tsev kawm ntawv. Hauv kuv lub tsev kawm ntawv, cov ntsiab cai ntawm bio yog npaj rau bio majors, qhov dav dav bio yog rau lwm yam loj uas xav tau biology, uas yuav yooj yim dua
Ib qho piv txwv ntawm overproduction nyob rau hauv cov tsiaj yog hiav txwv vaub kib hatchlings. Lub hiav txwv vaub kib tuaj yeem tso tau txog li 110 lub qe tab sis feem ntau ntawm lawv yuav tsis muaj sia nyob kom tsim tau cov xeeb ntxwv. Tsuas yog qhov zoo tshaj plaws yoov hiav txwv vaub kib yuav ciaj sia thiab yug me nyuam cov xeeb ntxwv
Cov tshuaj tiv thaiv ntawm phenylamine nrog dej Qhov no yog qhov muaj peev xwm qhia tau tias phenylamine yog lub hauv paus tsis muaj zog dua li ammonia thiab aliphatic amines xws li methylamine thiab ethylamine. Phenylamine reacts reversibly nrog dej muab phenylammonium ions thiab hydroxide ions
