Acetone yog cov kua tsis muaj xim, flammable kua uas evaporates yooj yim. Nws yog ib qho organic compound vim tias muaj cov pa roj carbon monoxide nyob hauv cov acetone chemical formula, uas yog (CH3) 2O. Nws muaj peb carbon atoms, rau hydrogen atoms, thiab ib tug oxygen atom.
Hais txog qhov no, puas yog huab cua sib xyaw?
Cua yog homogeneous sib tov, tsis yog a compound . Cov khoom sib xyaw ua ke tuaj yeem sib cais thaum lawv tau ua ke; a compound yog ib yam khoom tshiab tsim los ntawm cov tshuaj tiv thaiv ntawm cov khoom. Nws yog tsim los ntawm nitrogen, oxygen, thiab me ntsis ntawm carbon dioxide thiab argon thiab lwm yam, uas yog tag nrho cov tebchaw los yog molecules.
Tsis tas li ntawd, puas yog carbon ib lub ntsiab lus lossis cov khoom sib xyaw? Cov pa roj carbon yog ib keeb . Cia kuv sim piav qhov no. Ib keeb yog ib yam khoom uas yog tsim los ntawm ib hom atom (xws li hydrogen, oxygen, aluminium, kub, thiab lwm yam) Ntawm qhov tod tes, a compound yog ib yam khoom uas yog tsim los ntawm ob los yog ntau tshaj cov ntsiab lus (e.g. dej, carbon dioxide, ntsev, thiab lwm yam)
Hais txog qhov no, hom kev sib tov yog acetone?
Acetone yog ib qho tsis muaj xim, flammable, kua, organic compound (txhais tau tias nws muaj cov pa roj carbon) uas muaj carbondouble bonded rau ib qho oxygen thiab lwm yam carbon thiab hydrogenatoms. Acetone yog a hom ntawm ketone, uas yog anorganic molecule uas muaj ib pawg carbonyl (tab sis ntau ntxiv ntawm qhov ntawd).
Puas yog Silver ib qho khoom sib xyaw lossis sib xyaw?
Keeb Kwm teb: Dab tsi yog nyiaj , a sib tov sib xyaw los yog ib keeb ? Nyiaj yog ib keeb . Koj tuaj yeem pom nws ua cim "Ag" ntawm lub rooj zaum. Sterling nyiaj Txawm li cas los xij, yog ib qho alloy ( sib tov ntawm ob hlau) uas nyiaj yog ~ 92.5% nrog rau lwm cov hlau, feem ntau yog npib tsib xee lossis tooj liab, ua rau 7.5%.

Puas yog Oxygen yog cov khoom sib xyaw lossis sib xyaw?
Puas yog oxygen yog ib qho khoom sib xyaw lossis sib xyaw? Oxygen yog ib yam khoom. Nws yog tsim los ntawm tib hom atom, oxygen atoms (8 protons). Nws tshwm sim kom ruaj khov tshaj li molecules ntawm muaj pes tsawg leeg
Puas yog hluav taws xob yog cov khoom sib xyaw lossis sib xyaw?
Kev tshuaj xyuas cov ntsiab lus, cov khoom sib xyaw, thiab cov khoom sib xyaw Ionic Cov Khoom Siv Covalent Sib Nqus Sib cais rau hauv cov khoom siv hluav taws xob hauv dej kom muab cov kev daws teeb meem uas ua hluav taws xob nyob twj ywm zoo li qub molecule hauv dej thiab yuav tsis ua hluav taws xob
Puas yog Helium yog cov khoom sib xyaw lossis sib xyaw?
Helium atoms ib txwm muaj ob lub protons txhua, thiab hloov nws cov naj npawb ntawm cov protons yuav ua rau nws muaj qhov sib txawv tag nrho. Feem ntau cov khoom hauv peb lub ntiaj teb yog kev sib txuas ntawm cov ntsiab lus hu ua kev sib tov, nrog rau cov khoom sib xyaw ua ke hu ua cov tebchaw
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
Puas yog Krypton yog ib qho khoom sib xyaw lossis sib xyaw?
Krypton (Kr), cov khoom siv tshuaj, cov pa roj tsawg ntawm Pawg 18 (noble gases) ntawm lub sij hawm lub sij hawm, uas tsim cov tshuaj muaj pes tsawg leeg. Txog peb zaug hnyav dua huab cua, krypton tsis muaj xim, tsis muaj ntxhiab, tsis qab, thiab monatomic
