Cov Empirical Formula rau magnesium oxide yog MgO . Magnesium yog +2 cation thiab oxide yog -2 anion. Txij li cov nqi sib npaug thiab tawm tsam ob ions no yuav sib koom ua ke hauv 1 mus rau 1 piv ntawm atoms.
Tsis tas li ntawd nug, dab tsi yog cov qauv ntawm magnesium oxide?
MgO
Kuj Paub, lub mis MgO txhais li cas? Magnesium oxide (MgO), los yog magnesia, yog ib tug dawb hygroscopic khoom ntxhia uas tshwm sim ib txwm li periclase thiab yog ib qhov chaw ntawm magnesium (saib oxide). Thaum " magnesium oxide " ib txwm hais txog MgO , magnesium peroxide MgO 2 yog kuj hu ua ib tug compound.
Kuj paub, dab tsi yog qhov theoretical formula ntawm magnesium oxide?
Qhov tseeb qauv rau magnesium oxide yog MgO , a 1.0 to 1.0 ratio.
Magnesium oxide tsim li cas?
Oxygen thiab magnesium ua ke nyob rau hauv ib qho tshuaj tiv thaiv rau daim ntawv no compound. Tom qab nws hlawv, nws tsim cov hmoov dawb ntawm cov magnesium oxide . Magnesium muab ob lub electrons rau oxygen atoms rau daim ntawv cov khoom hmoov no. Qhov no yog ib qho tshuaj tiv thaiv exothermic.

Thaum lub ntim ntawm ib qho piv txwv ntawm cov pa roj yog txo lub siab ntawm cov qauv ntawm cov pa roj?
Kev txo qis Cov pa roj sib xyaw txoj cai hais tias lub siab ntawm cov pa roj yog inversely cuam tshuam nrog lub ntim thiab ncaj qha ntsig txog qhov kub thiab txias. Yog tias qhov kub thiab txias yog nyob tas li, qhov sib npaug raug txo rau Boyle txoj cai. Yog li ntawd, yog tias koj txo qhov siab ntawm cov roj av tas li, nws qhov ntim yuav nce ntxiv
Cov yam ntxwv twg ntawm cov hlau atoms pab piav qhia vim li cas valence electrons hauv cov hlau yog delocalized?
Ib daim ntawv cog lus hlau yog kev sib koom ntawm ntau cov khoom siv hluav taws xob sib cais ntawm ntau cov ions zoo, qhov twg cov electrons ua raws li 'cov kua nplaum' muab cov khoom tsim nyog. Nws tsis zoo li covalent lossis ionic bonding. Cov hlau muaj zog ionization tsawg. Yog li ntawd, valence electrons tuaj yeem raug delocalized thoob plaws hauv cov hlau
Ntau npaum li cas ntawm cov pej xeem hauv ntiaj teb nyob ntawm cov kab ke roob rau tag nrho lossis qee qhov ntawm lawv cov dej?
Roob yog lub ntiaj teb "dej yees," muab 60-80% ntawm tag nrho cov dej tshiab rau peb ntiaj chaw. Tsawg kawg ib nrab ntawm lub ntiaj teb cov pej xeem nyob ntawm roob ecosystem kev pabcuam kom muaj sia nyob - tsis yog dej xwb, tab sis kuj muaj zaub mov thiab lub zog huv
