Ca( OH) 2 yog ib qho ionic compound, uas Ca yog cation thiab OH yog anion. Ca (calcium) muaj a nqi ntawm 2+, vim nws yog nyob rau hauv pawg 2 ntawm lub sij hawm lub rooj. OH (hydroxide) yog polyatomic ion nrog a nqi ntawm -1.
Ib yam li ib tug yuav nug, tus nqi ntawm AS yog dab tsi?
Table of Common Element Charges
Tus lej | Element | Them nqi |
---|---|---|
30 | zinc | 2+ |
31 | gallium | 3+ |
32 | germanium | 4-, 2+, 4+ |
33 | arsenic | 3-, 3+, 5+ |
Tom qab ntawd, lo lus nug yog, ua li cas koj paub tus nqi ntawm polyatomic ion? xam Los ntawm Oxidation Number Tus oxidation tooj ntawm oxygen yog -2, thiab oxidation naj npawb ntawm hydrogen yog +1. Ntxiv ua ke cov oxidation tooj ntawm tag nrho cov atoms nyob rau hauv lub polyatomic ion . Hauv qhov piv txwv, -2 +1 = -1. Qhov no yog qhov nqi ntawm polyatomic ion.
Tus nqi ntawm OH 2 yog dab tsi?
Ca( OH ) 2 yog ib qho ionic compound, uas Ca yog cation thiab OH yog anion. Ca (calcium) muaj a nqi ntawm 2 +, vim nws nyob hauv pab pawg 2 nyob rau ntawm lub rooj sib tham. OH (hydroxide) yog polyatomic ion nrog a nqi ntawm -1.
Tus nqi ntawm MG yog dab tsi?
Raws li qhov kawg tshwm sim, muaj qhov +2 nqi ntawm magnesium ion, raws li muaj ib tug nqi Qhov sib txawv ntawm 2 electrons 'tus nqi, tab sis nyob rau hauv ib txoj kev uas muaj ntau dua qhov zoo nqi.

Dab tsi yog qhov txawv ntawm ib puag ncig lapse tus nqi thiab adiabatic lapse tus nqi?
A. Ib puag ncig lapse tus nqi yog hais txog qhov kub thiab txias nrog nce qhov siab hauv troposphere; uas yog qhov kub ntawm ib puag ncig ntawm qhov chaw sib txawv. Nws implies tsis muaj huab cua txav. Adiabatic txias tsuas yog cuam tshuam nrog huab cua ascending, uas txias los ntawm kev nthuav dav
Dab tsi yog ib puag ncig lapse tus nqi thiab adiabatic lapse tus nqi?
Recap • Lapse Rate yog tus nqi uas kub qis dua thaum qhov siab nce hauv huab cua • Ib puag ncig lapse tus nqi yog tus nqi uas kub qis dua thaum tus nqi tsis cuam tshuam los ntawm huab cua saturation • Environmental lapse rate txo sai dua thaum huab cua tsis ruaj khov. tsis ruaj khov
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
Txhais li cas los ntawm tus nqi ntws ntawm tus nqi hluav taws xob?
Ib coulomb ib ob
Tus qauv qauv yog dab tsi Qhov txawv ntawm tus qauv qauv thiab tus qauv molecular yog dab tsi?
Cov mis mos molecular siv cov cim tshuaj thiab cov ntawv sau npe los qhia cov naj npawb ntawm cov atoms sib txawv hauv cov molecule lossis compound. Ib qho empirical formula muab qhov yooj yim tshaj plaws, tag nrho tus lej piv ntawm atoms hauv ib qho chaw. Cov qauv qauv qhia txog kev sib koom ua ke ntawm cov atoms hauv cov molecule
