Molar loj ntawm Cl 2 ( g yog 70,9060 g /mol. Hloov ntawm Cl 2 ( g ) hnyav thiab moles. Compound. Moles.
Hais txog qhov no, lub npe rau cl2 yog dab tsi?
Cl 2 yog tus qauv ntawm ib molecule ntawm tshuaj chlorine gas. Chemical cim ntawm tshuaj chlorine tsuas yog Cl.
Qhov thib ob, yog cl2 molecular? Nws yog ob leeg. Nws yog ob lub atom ntawm lub ntsiab tshuaj chlorine , chemically bonded ua ke rau hauv ib leeg tshuaj chlorine molecule . Lo lus "element" tsis zoo ib yam li atom. Cl 2 yog tsim los ntawm ib lub ntsiab lus tshuaj chlorine tab sis nws qhov tsawg tshaj plaws yog 2 atoms tsim rau hauv ib leeg molecule.
Kuj Paub, dab tsi yog enthalpy ntawm cl2?
Standard Enthalpies ntawm Tsim cov Gaseous Atoms
| Atom | Δ Hf°(g) kJ/mol |
|---|---|
| Cov pa roj carbon | 717 |
| Cerium | 422 |
| Cesium | 79 |
| Chlorine | 121 |
Vim li cas chlorine thiaj li muaj li cl2?
Chlorine ua tau muaj raws li ib leeg tshuaj chlorine atom, hu ua radical. Vim Cl2 yog ruaj khov ntau dua li ib leeg xwb tshuaj chlorine atom. Cl muaj 7 electrons nyob rau hauv nws lub plhaub sab nrauv, lub ntsiab lus kom tau txais cov khoom siv hluav taws xob zoo (ruaj khov) nws yuav tsum tau txais ib qho hluav taws xob ntxiv.
