Hydroxide OH - muaj a nqi ntawm -1. Cov Oxygen muaj tus lej oxidation -2 thiab hydrogen muaj tus lej oxidation +1.
Tsis tas li ntawd, tus nqi ntawm O yog dab tsi?
Cov ionic them cov pa oxygen yog -2. Koj qhia tau vim oxygen yog nyob rau hauv pawg naj npawb 6, yog li nws muaj 6 valence electrons. Txij li thaum nws xav tau 2 ntau electrons los ua nruab nrab nrog lub plhaub sab nrauv ntawm 8 electrons, nws nqi yog -2 (txij li thaum ntxiv electrons muab qhov tsis zoo nqi ).
Tsis tas li, vim li cas OH thiaj li muaj qhov tsis zoo? Nyob rau hauv no compound, oxygen bonds nrog hydrogen los ntawm kev sib koom ob electrons. Hydroxide nqa a tus nqi tsis zoo vim nws muaj tau txais ib qho hluav taws xob. Oxygen, piav raws li O, yog bonded rau hydrogen, depicted li H, thiab peb tuaj yeem pom qhov twg ntau tshaj tsis zoo ib feem ntawm lub compound yog nrog rau tsis zoo kos npe.
Kuj tseem yuav paub, dab tsi yog cov nqi raug cai ntawm O thiab H hauv hydroxide ion OH?
Cov raug nqi yog 6-6=0. Tam sim no xav txog qhov hydroxide ion , OH -. Cov oxygen hauv hydroxide muaj 7 electron muab rau nws: 6 nonbonding thiab 1 bonding. Cov raug nqi yog 6-7=-1.
Tus nqi ntawm C yog dab tsi?
Yog li ntawd, a carbon ion tuaj yeem muaj nqi ntawm qhov twg los ntawm -4 txog +4, nyob ntawm seb nws poob lossis nce electrons. Txawm hais tias feem ntau oxidation xeev ntawm carbon yog +4 thiab +2, carbon Nws muaj peev xwm ua ions nrog oxidation xeev ntawm +3, +1, -1, -2, thiab -3.

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
