Lub npe ntawm cov khoom xyaw nrog cov mis CuCrO4 yog dab tsi?
Copper(II) Chromate CuCrO4 Molecular Luj --EndMemo
Dab tsi yog qhov me me ntawm cov khoom uas khaws cov khoom ntawm lub caij?
Ib qho atom yog qhov tsawg tshaj plaws ntawm txhua lub caij uas tseem khaws cov yam ntxwv ntawm lub caij ntawd. Ib daim ntawm ib lub caij uas peb tuaj yeem pom lossis kov yog ua los ntawm ntau, ntau atoms thiab tag nrho cov atoms yog tib yam lawv txhua tus muaj tib tus naj npawb ntawm protons
Lub npe ntawm cov enzyme uas catalyzes ntawm cov synthesis ntawm mRNA Strand yog dab tsi?
MRNA yog "tus tub txib" RNA. mRNA yog synthesized nyob rau hauv lub nucleus siv cov nucleotide ib theem zuj zus ntawm DNA ua ib tug template. Cov txheej txheem no yuav tsum muaj nucleotide triphosphates ua substrates thiab yog catalyzed los ntawm enzyme RNA polymerase II. Tus txheej txheem ntawm kev ua mRNA los ntawm DNA yog hu ua transcription, thiab nws tshwm sim nyob rau hauv lub nucleus
Dab tsi yog txhais los ntawm lub sij hawm dissociation thiab dab tsi yog ib qho piv txwv ntawm cov khoom uas dissociates?
Dissociation, nyob rau hauv chemistry, sib cais ntawm ib yam khoom mus rau hauv atoms los yog ions. Thermal dissociation tshwm sim ntawm qhov kub thiab txias. Piv txwv li, hydrogen molecules (H 2) dissociate rau hauv atoms (H) ntawm kub heev; ntawm 5,000 ° K txog 95% ntawm cov molecules hauv cov qauv ntawm hydrogen yog dissociated rau hauv atoms
Lub npe ntawm tag nrho cov ntsiab lus ntawm lub sij hawm lub rooj yog dab tsi?
Tus lej xov tooj yog nws tus lej atomic, uas yog tus naj npawb ntawm protons hauv txhua qhov ntawm nws cov atoms. H - Hydrogen. Nws - Helium. Lithium roj teeb. Ua - Beryllium. B - Boron. C - Cov pa roj carbon. N - Nitrogen. O - Cov pa
