Molecular solids - Ua los ntawm atoms ormolecules tuav ua ke los ntawm London dispersion rog, dipole-dipoleforces, los yog hydrogen bonds. Ib qho piv txwv ntawm a molecular khoom yog sucrose. Covalent -network (tseem hu ua atomic) cov khoom khib nyiab - Ua los ntawm atoms txuas nrog covalent daim ntawv cog lus; lub zog intermolecular yog covalent bonds ib yam.
Ua raws li qhov no hauv kev xav, cov piv txwv ntawm molecular solids yog dab tsi?
Piv txwv ntawm Molecular Solids
- Dej khov.
- Khoom carbon dioxide.
- Sucrose, los yog qab zib.
- Hydrocarbons.
- Fullerenes.
- Sulfur.
- Dawb phosphorus.
- Yellow arsenic.
Kuj Paub, cov khoom ntawm molecular solids yog dab tsi? Cov khoom . Txij li thaum molecular solids koom ua ke los ntawm cov zog tsis muaj zog uas lawv yuav muaj cov ntsiab lus qis thiab kub, tsis tshua muaj zog, tsis muaj hluav taws xob, thiab thermal conductivity tsis zoo.
Ib yam li ntawd, nws raug nug, dab tsi yog atomic solids?
Piv txwv ntawm atomic solids suav nrog cov hlau ntshiab, silicon crystals, thiab pob zeb diamond. Atomic solids hauv qhov twg atoms yog covalently bonded rau ib leeg yog network cov khoom khib nyiab.
Yam khoom twg yog MG?
11.8: Kev sib koom ua ke hauv cov khoom
| Hom Khoom | Kev sib tham | Piv txwv |
|---|---|---|
| Ionic | Ionic | NaCl, MgO |
| Molecular | Hydrogen Bonding, Dipole-Dipole, London Dispersion | H2, CO2 |
| Hlau | Hlau Bonding | Fe, Mg |
| Network | Covalent Bonding | C (pob zeb diamond), SiO2 (quartz) |

Dab tsi yog qhov txawv ntawm qhov pom tseeb qhov loj thiab qhov ntsuas qhov ntsuas qhov tseeb?
Dab tsi yog qhov txawv ntawm qhov pom tseeb thiab qhov tseeb? Pom meej qhov loj npaum li cas yog qhov ci ntawm lub hnub qub tshwm los ntawm lub ntiaj teb thiab nyob ntawm qhov ci thiab qhov deb ntawm lub hnub qub. Qhov loj npaum li cas yog qhov ci ntawm lub hnub qub yuav tshwm sim los ntawm tus qauv nyob deb
Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Dab tsi yog qhov sib txawv ntawm qhov sib txawv ntawm cov kab sib txuas thiab ntau qhov sib piv?
6. (2 lub cim) Qhov sib txawv ntawm cov kab sib txuas (kev sib piv) thiab ntau qhov sib piv yog dab tsi? Cov kab sib xyaw ua ke yog npaj sib piv; uas yog, tshwj xeeb txhais tau tias yog ua ke nyob rau hauv ntau txoj kev thiab contrasted nrog rau lwm yam kev sib txuas ntawm txhais tau tias
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
Dab tsi yog qhov txawv ntawm instantaneous thiab nruab nrab ceev dab tsi yog qhov piv txwv loj tshaj ntawm kev ceev ceev?
Qhov nruab nrab ceev yog qhov ceev nruab nrab ntawm lub sijhawm. Instantaneous ceev yuav yog qhov ceev txhua qhov muab tam sim ntawd hauv lub sijhawm ntawd, ntsuas nrog lub ntsuas ntsuas lub sijhawm
