Oxygen yog ib qho khoom xyaw los yog a sib tov ? Oxygen yog ib keeb . Nws tsuas yog ua los ntawm ib hom atom xwb, oxygen atoms (8 protons). Nws tshwm sim kom ruaj khov tshaj li molecules ntawm muaj pes tsawg leeg.
Ua kom pom qhov no, puas yog Oxygen lub ntsiab lossis cov khoom sib xyaw?
Hauv nws qhov xwm txheej tshwm sim, oxygen ob yog ib keeb thiab molecule, tab sis nws tsis yog ib compound . Nws yog ib qho atomically homogeneous khoom, txhais tau hais tias tsis muaj lwm hom atoms hauv ib qho oxygen molecule. Uas ua rau nws yog ib tug ntshiab keeb.
Ib yam li ntawd, puas yog pob zeb ua ib qho khoom sib xyaw lossis sib xyaw? Cement yog a sib tov vim nws yog tsim los ntawm ntau hom compound cov khoom. Txhua yam ntawm cov khoom pob zeb los ntawm lawv tus kheej yuav yog cov khoom ntshiab. Piv txwv li, ib qho piv txwv ntawm cov calcium oxide xwb yuav yog cov khoom ntshiab vim hais tias cov khoom hauv cov qauv yuav zoo tib yam calcium oxide. tshuaj sib xyaw.
Tsis tas li ntawd, puas yog huab cua ib qho khoom sib xyaw lossis cov khoom sib xyaw?
Cua yog qhov sib tov uas muaj cov ntsiab lus nitrogen, oxygen thiab argon, thiab kuj cov compound carbon dioxide.
Dab tsi yog qhov sib tov yog oxygen?
Gaseous Homogeneous Mixtures Cov huab cua uas koj ua pa yog homogeneous sib xyaw ntawm oxygen, nitrogen , argon, thiab carbon dioxide, nrog rau lwm cov ntsiab lus me me. Vim tias txhua txheej ntawm lub ntiaj teb huab cua muaj qhov sib txawv, txhua txheej ntawm huab cua yog nws qhov sib xyaw ua ke.

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 acetone yog cov khoom sib xyaw lossis cov khoom?
Acetone yog cov kua uas tsis muaj xim, flammable kua uas evaporates yooj yim. Nws yog ib qho organic compound vim tias carbonatoms muaj nyob rau hauv acetone cov tshuaj formula, uas yog (CH3) 2O. Nws muaj peb carbon atoms, rau hydrogen atoms, thiab ib tug oxygen atom
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
