Yog lawm, carbon dioxide yog cov khoom ntshiab tsis yog sib tov. Piv txwv ntawm cov khoom ntshiab suav nrog cov ntsiab lus xws li hlau, nyiaj, mercury thiab lwm yam. Thiab cov ntsiab lus zoo li dej, carbon dioxide , methane, vinegar.
Ua qhov no hauv kev txiav txim siab, puas yog carbon dioxide sib xyaw lossis sib xyaw?
CO2 yog a compound npe carbon dioxide . Cov khoom uas ua rau sib tov tuaj yeem yog cov khoom lossis cov khoom sib txuas, tab sis sib tov tsis txhob tsim cov ntawv cog lus tshuaj. Cov khoom xyaw tuaj yeem muab cais rau hauv lawv cov khoom qub ib zaug ntxiv (kwv yees) yooj yim.
Tom qab ntawd, lo lus nug yog, puas yog carbon dioxide homogeneous lossis heterogeneous? Cov pa roj carbon dioxide tsis yog heterogenous lossis homogeneous sib tov . Nws yog ib tug compound, qhov twg txawv cov ntsiab lus yog chemically bonded ua ke. Nws tuaj yeem suav hais tias yog homogeneous, vim nws yog ib qho zoo sib xws hauv kev sib xyaw thoob plaws, tab sis nws tsis raug hu ua a sib tov , tab sis ib qho kev sib xyaw.
Ib yam li ntawd, koj tuaj yeem nug, vim li cas ib qho piv txwv ntawm co2 suav hais tias yog cov khoom ntshiab?
Cov pa roj carbon dioxide yog a compound uas muaj ob lub atom ntawm oxygen thiab ib tug atom ntawm carbon. Cov tshuaj ntshiab tsis tas yuav tsum sib xyaw thiab tsis tuaj yeem tawg yam tsis muaj txheej txheem nyuaj. Vim carbon dioxide yog ntuj thiab tsis tuaj yeem tawg tau yooj yim, nws yog cov khoom ntshiab.
Puas yog huab cua ntshiab huv?
Teb thiab piav qhia: Cua tsis yog a cov khoom ntshiab vim nws yog homogeneous sib tov sib txawv tshuaj . Cua yog homogeneous sib tov vim huab cua yog ib tug kom huv si

Puas yog sodium hydrogen carbonate nqus cov pa roj carbon dioxide?
Tsis yog kiag li. Qhov tseeb, nws ua qhov txawv. Thaum reacting nrog ib tug acid los yog kub tshaj 200 degrees C, nws FORMS carbon dioxide. Koj qhov tsis meej pem tej zaum yuav yog tias nws yog qhov khoom kawg ntawm cov tshuaj tiv thaiv ntawm sodium hydroxide nrog carbon dioxide
Cov pa roj carbon dioxide puas muaj qhov kub thiab txias?
78.46°C dej
Puas yog cov pa roj carbon dioxide yog qhov sib xyaw lossis sib xyaw?
CO2 yog lub npe hu ua carbon dioxide. Ib lub ntsiab yog ib yam khoom ua los ntawm ib hom atom. Cov tshuaj uas tsim cov khoom sib tov tuaj yeem yog cov khoom lossis cov khoom sib txuas, tab sis cov khoom sib tov tsis tsim cov tshuaj sib txuas. Cov khoom sib xyaw tuaj yeem sib cais rau hauv lawv cov khoom qub ib zaug ntxiv (kwv yees) yooj yim
Thaum koj kub calcium carbonate ib qho khoom dawb nrog cov mis CaCO3 nws tawg los ua cov khoom calcium oxide CaO thiab carbon dioxide gas co2?
Thaum tshav kub kub tshaj 840 ° C, calcium carbonate decomposes, tso cov pa roj carbon dioxide thiab tawm hauv qab calcium oxide - cov khoom dawb. Calcium oxide hu ua txiv qaub thiab yog ib qho ntawm 10 cov tshuaj uas tsim tawm txhua xyoo los ntawm thermal decomposition ntawm limestone
Puas yog carbon dioxide yog cov khoom sib xyaw lossis sib xyaw?
Nws txhais tau hais tias muaj ib lub atom ntawm carbon thiab ob atoms ntawm Oxygen bonded ua ke ua ib tug molecule hu ua carbon dioxide. Ib qho molecule yog qhov tsawg tshaj plaws uas muaj peev xwm muab faib tau thiab tseem yog nws tus kheej thiab qhov sib tov yog thaum cov tshuaj tsuas yog sib xyaw ua ke xws li ntsev thiab kua txob
