Helium atoms ib txwm muaj ob lub protons txhua, thiab hloov nws cov naj npawb ntawm protons yuav ua rau nws txawv keeb tag nrho. Feem ntau ntawm peb lub ntiaj teb yog kev sib xyaw ua ke cov ntsiab lus npe a sib tov , suav nrog kev sib koom ua ke cov ntsiab lus hu ua compounds.
Tom qab ntawd, ib tug kuj nug, yog Helium sib tov?
Helium yog ib yam khoom ntshiab. Feem ntau, helium gas ib sib tov ntawm 2 txawv hom ntawm helium (isotopes). Helium yog ib yam khoom ntshiab. Feem ntau, helium gas ib sib tov ntawm 2 txawv hom ntawm helium (isotopes).
Tom qab ntawd, lo lus nug yog, Vinegar yog ib qho khoom sib xyaw lossis sib xyaw? Vinegar yog homogenous sib xyaw ntawm acetic acid thiab dej . Raws li kev sib xyaw tsim muaj tsuas yog ib theem nws yog kev daws teeb meem. Kev sib xyaw yog tsim los ntawm kev sib xyaw ob lossis ntau yam tshuaj lom neeg. Yog tias qhov tshwm sim muaj ntau tshaj ib theem nws raug xa mus rau qhov sib tov lwm qhov nws hu ua kev daws teeb meem.
Yog li, carbon dioxide puas yog cov khoom sib xyaw lossis sib xyaw?
Cov pa roj carbon dioxide , CO2 , yog tshuaj compound tsim ob lub atoms oxygen covalently bonded rau ib leeg carbon atom.
Daim ntawv puas yog cov khoom sib xyaw lossis sib xyaw?
1 Teb. Tsis muaj cov cim tshuaj rau daim ntawv vim nws tsis yog ib qho khoom tab sis yog qhov sib xyaw ntawm ntau qhov sib txawv. Nco ntsoov tias daim ntawv yog ua los ntawm cov ntoo. Yog li, daim ntawv feem ntau yog ua los ntawm cov organic tebchaw: uas yog carbon, hydrogen thiab oxygen (C, H thiab O).
