Tooj (Kuv) ions muaj 1+ nqi . Nws cov qauv yog Cu +. Tooj (II) ions muaj 2+ nqi . Qhov no tshwm sim thaum tooj liab atoms poob ob electrons.
Yog li ntawd, qhov ion ntawm tooj liab yog dab tsi?
Tooj (2+) yog ib ion ntawm tooj liab nqa ib tug nqi ob npaug. Nws muaj lub luag haujlwm ua tus cofactor. Nws yog divalent hlau cation, a tooj liab cation thiab monoatomic dication.
Tsis tas li ntawd, tooj liab puas zoo lossis tsis zoo ion? Cov ions zoo yog cations thiab feem ntau yog hlau zoo li tooj liab los yog sodium. Negatively them ions yog anions, tsim los ntawm nonmetallic ntsiab zoo li oxygen thiab sulfur.
Ib yam li ntawd, vim li cas tooj liab thiaj li muaj 2+ nqi?
Vim lub nqi teb ceev ntawm lub tooj liab atom's electron huab txav 4s rau hauv 3d. Nyob rau hauv zinc nws yuav ntxiv ib tug thib ob electron rau 4s. Yog li, tooj liab yeej yog muaj 2 valence electrons nws ua tau poob, muab nws lub xeev oxidized ntawm 2 +.
Cov qauv ntawm tooj liab yog dab tsi?
Qauv . Tooj muaj lub ntsej muag nruab nrab cubic (FCC) siv lead ua qauv . Tooj thiab nws cov alloys muaj ntau yam xim daj / kub / xim liab thiab thaum polished tsim lub ci xim hlau ci.

Tus naj npawb ntawm protons hauv tooj liab yog dab tsi?
29 Tsis tas li ntawd, muaj pes tsawg protons neutrons thiab electrons muaj tooj liab? Tooj liab muaj tus lej atomic ntawm 29 , yog li nws muaj 29 proton thiab 29 electrons. Qhov hnyav atomic (tej zaum hu ua atomic mass) ntawm ib lub atom yog kwv yees los ntawm cov lej ntawm cov protons thiab cov naj npawb ntawm cov neutrons hauv lub nucleus ntawm lub atom.
Cov qauv siv lead ua ntawm tooj liab sulfate yog dab tsi?
Copper(II) sulfate Names Structure Crystal structure Orthorhombic (anhydrous, chalcocyanite), space group Pnma, oP24, a = 0.839 nm, b = 0.669 nm, c = 0.483 nm. Triclinic (pentahydrate), qhov chaw pab pawg P1, aP22, a = 0.5986 nm, b = 0.6141 nm, c = 1.0736 nm, α = 77.333 °, β = 82.267 °, γ = 72.567 ° Thermochemist
Qhov loj ntawm 3.5 moles ntawm tooj liab yog dab tsi?
Qhov loj ntawm Cu hauv grams tuaj yeem tau los ntawm kev sib npaug ntawm qhov loj hauv amu nrog Avogadro tus lej. Yog li ntawd, qhov loj ntawm 3.5 moles ntawm Cu yog 3.69 × 10 − 22 grams 3.69 × 10 − 22g ua
Dab tsi yog qhov txawv ntawm Biot tooj thiab Nusselt tooj?
Cov lus teb tsis ntev los no. Biot tooj siv thermal conductivity ntawm lub cev (tsis yog kua), whereas Nusselt tooj siv thermal conductivity ntawm cov kua. Qhov sib txawv ntawm Biot thiab Nusselt tus naj npawb yog nyob rau hauv lub ntsiab lus ntawm tshav kub hloov coefficient, uas yog txhais raws li: h = -k (dT / dn) w / (Tw-T0)
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
