Rau qhov TSIS MUAJ 2 Lewis qauv, xam tag nrho cov naj npawb ntawm valence electrons rau lub TSIS MUAJ 2 molecule. Tom qab txiav txim siab pes tsawg valence electrons muaj nyob rau hauv TSIS MUAJ 2 , muab lawv nyob ib ncig ntawm lub hauv paus atom kom tiav cov octets.
Tsis tas li ntawd, tsis muaj 2 leeg muaj khub?
TSIS MUAJ2 - muaj ib tug ntau dua electron TSIS MUAJ2 , yog li ntawd muaj kev tsis sib haum xeeb khub (" ib khub ") ntawm electrons ntawm nitrogen TSIS MUAJ2 , yog li lub kaum sab xis O-N-O txo ntxiv, mus rau 115.4 °.
Tsis tas li ntawd, no2 tsw zoo li cas? Nitrogen oxides, TSIS thiab TSIS MUAJ 2 raws li TSIS MUAJ 2 . Oxides ntawm nitrogen (NOx) yog lo lus feem ntau siv los xa mus rau nitrogen monoxide (nitric oxide lossis NO; roj tsis muaj xim thiab tsis muaj ntxhiab) thiab nitrogen dioxide ( TSIS MUAJ 2 ; liab-xim av nrog ib tug pungent tsw uas yog soluble hauv dej).
qhov txawv ntawm no2 thiab no2 yog dab tsi?
Keeb Kwm teb: Dab tsi yog qhov txawv ntawm NO2 - (nitrite) thiab TSIS MUAJ 2 (nitrogen dioxide)? Ob hom tshuaj sib txawv tsuas yog ib qho hluav taws xob xwb. Nitrite ion muaj tus nqi tsis zoo vim hais tias ib qho hluav taws xob ntxiv tau ntxiv rau ua ke nrog cov hluav taws xob tsis sib xws hauv TSIS MUAJ 2.
Vim li cas tsis muaj 2 Brown hauv Xim?
Vim li cas nitrogen oxide tsis muaj xim thaum nitrogen dioxide yog xim av xim ? Yog vim li cas peb thiaj pom tias cov roj Nitrogen yog cov roj dawb (yog tias cov roj yog concentrated txaus). Raws li rau nitrogen dioxide , cov molecules nqus ib yam xim. Tag nrho lwm yam xim yog reflected li ib xim av xim.
