Cov pa roj carbon dioxide feem ntau tshwm sim raws li cov pa tsis muaj xim. Nyob rau hauv daim ntawv, nws yog hu ua qhuav dej khov. Cov tshuaj los yog molecular formula rau carbon dioxide yog CO2. Lub hauv paus carbon atom koom nrog ob lub pa oxygen atom los ntawm covalent ob daim ntawv cog lus.
Ib yam li ntawd, tib neeg nug, koj ua li cas co2?
Ntxiv 2 tablespoons baking soda rau hauv lub raj mis dej qab zib maj mam siv koj lub funnel. Cov baking soda thiab vinegar yuav fizz. Cov roj uas tau muab tawm yog carbon dioxide. Ntxiv cov baking soda kom txog thaum tsis muaj fizzing ntxiv.
Tsis tas li ntawd, cov mis ntawm oxygen thiab carbon dioxide yog dab tsi? Cov pa roj carbon dioxide yog ib qho tshuaj sib xyaw ua ke ntawm ib qho carbon thiab ob oxygen atoms. Nws yog feem ntau xa mus rau nws formula CO2.
Tsis tas li ntawd, yog co2 yog ib qho qauv ntawm cov qauv?
Txij li qhov tshwm sim piv yog ib qho carbon rau ob lub pa oxygen atoms, lub empirical formula yog CO2.
Dab tsi yog carbon dioxide siv rau hauv lub neej txhua hnub?
Cov pa roj carbon dioxide kuj yog siv dav raws li ib tug coolant, refrigerant, thiab ib tug muaj nyob rau hauv kev tsim cov khoom noj khov. Cov pa roj carbon dioxide Cov hluav taws tua hluav taws ntau zaus siv tswj hluav taws xob thiab roj hluav taws xob, uas tsis tuaj yeem muab tso rau hauv dej.

Cov mis loj ntawm ib yam khoom yog qhov sib npaug ntawm qhov nruab nrab atomic masses ntawm txhua lub atom sawv cev hauv cov tshuaj formula thiab qhia nyob rau hauv atomic mass units. Cov mis loj ntawm covalent compound tseem hu ua molecular mass
Thaum muab piv cov qauv sau rau ib tus neeg raug liam cov ntaub ntawv lub hnub nyoog sib txawv ntawm cov ntaub ntawv yuav tsum tsis pub tshaj kaum ob lub hlis?
Thaum piv cov qauv sau rau tus neeg raug liam? cov ntaub ntawv, lub hnub nyoog sib txawv ntawm cov ntaub ntawv yuav tsum tsis pub ntau tshaj rau rau kaum ob lub hlis. Tus lej txaus ntawm tus qauv yog qhov tseem ceeb rau kev txiav txim siab qhov tshwm sim ntawm kev sib piv
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
Koj sau cov qauv li cas rau binary ionic compounds?
Formulas rau binary compounds pib nrog cov hlau ua raws li cov nonmetal. Cov nqi zoo thiab tsis zoo yuav tsum thim tawm ib leeg. Cov qauv ionic compound yog sau siv qhov qis tshaj ntawm ions
Koj sau cov npe tshuaj thiab cov qauv li cas?
Thaum sau cov mis, qhov zoo atom lossis ion los ua ntej los ntawm lub npe ntawm qhov tsis zoo ion. Lub npe tshuaj rau cov lus ntsev yog sodium chloride. Lub sij hawm lub sij hawm qhia tau hais tias lub cim rau sodium yog Na thiab lub cim rau chlorine yog Cl. Cov tshuaj formula rau sodium chloride yog NaCl
