- Ionic sib tov / Molecular Compound Lub npe.
- Thaum twg npe tshuaj sib xyaw , thawj yam uas koj yuav tsum tau ua yog txiav txim siab yog tus compound yog ionic molecular .
- Saib cov ntsiab lus hauv lub compound .
- * Ionic tshuaj sib xyaw yuav muaj ob qho tib si hlau thiab tsis yog hlau, los yog tsawg kawg yog ib tug polyatomic ion.
- * Molecular compounds yuav tsuas muaj cov hlau tsis muaj hlau.
Ua kom pom qhov no, dab tsi ua rau ib yam dab tsi molecular compound?
A molecular compound tuaj yeem txhais tau tias yog a compound qhov twg cov atoms qhia electrons los ntawm covalent bonds. Nws tseem hu ua covalent compound . Covalent bonds yog dab tsi tuav molecule ua ke. Thaum atoms sib koom electrons, lawv muaj peev xwm muaj tag nrho cov sab nrauv electron plhaub.
Ib yam li ntawd, qee qhov piv txwv ntawm ionic compounds yog dab tsi? Ionic daim ntawv cog lus piv txwv muaj xws li:
- LiF - Lithium Fluoride.
- LiCl - Lithium Chloride.
- LiBr - Lithium Bromide.
- Li-Iodide Lithium Iodide.
- NaF - Sodium Fluoride.
- NaCl - Sodium Chloride.
- NaBr - Sodium Bromide.
- NaI - Sodium Iodide.
Hauv qhov no, piv txwv li molecular compound yog dab tsi?
Molecular compounds yog inorganic tshuaj sib xyaw uas coj daim ntawv ntawm discrete molecules . Piv txwv suav nrog xws li paub tshuaj xws li dej (H2O) thiab carbon dioxide (CO2). Ionic tshuaj sib xyaw yog tsim thaum hlau atoms poob ib los yog ntau tshaj ntawm lawv cov electrons rau nonmetal atoms.
Dab tsi yog ionic thiab molecular compounds muab piv txwv?
Teb: Ionic compounds : Ionic compounds yog tsim los ntawm kev hloov ntawm electrons yog hu ua ionic compound . Daim ntawv cog lus pom hauv cov no tshuaj sib xyaw yog ionic nyob rau hauv qhov. Molecular compounds tuaj yeem muaj nyob hauv cov khoom, kua lossis gaseous xeev. Piv txwv Cov khoom siv: carbon dioxide, carbon monoxide, hydrogen chloride, dej, methane thiab lwm yam.

Yuav ua li cas koj paub yog hais tias ib tug diploid yog haploid?
Muaj ob hom hlwb hauv lub cev - cov hlwb haploid thiab cov hlwb diploid. Daim duab piv. Diploid Haploid Txog Diploid hlwb muaj ob pawg ua tiav (2n) ntawm chromosomes. Haploid hlwb muaj ib nrab ntawm cov chromosomes (n) raws li diploid - piv txwv li lub cell haploid tsuas muaj ib pawg chromosomes xwb
Yuav ua li cas koj paub yog hais tias ib tug txheej txheem yog spontaneous?
Los ntawm kev xav txog ob yam no, peb tuaj nrog Gibbs Free Energy sib npaug los kwv yees seb qhov kev cuam tshuam yuav tshwm sim li cas lossis tsis ua. Yog tias Gibbs Dawb Zog yog qhov tsis zoo, ces cov tshuaj tiv thaiv yog tshwm sim, thiab yog tias nws yog qhov zoo, ces nws tsis yog tshwm sim
Yuav ua li cas koj thiaj paub yog hais tias ib tug function tsis yog ib tug function?
Kev txiav txim siab seb qhov kev sib raug zoo yog qhov ua haujlwm ntawm daim duab yog qhov yooj yim los ntawm kev siv cov kab ntsug. Yog tias txoj kab ntsug hla qhov kev sib raug zoo ntawm daim duab ib zaug hauv txhua qhov chaw, qhov kev sib raug zoo yog qhov ua haujlwm. Txawm li cas los xij, yog tias txoj kab ntsug hla qhov kev sib raug ntau dua ib zaug, qhov kev sib raug zoo tsis muaj nuj nqi
Yuav ua li cas koj paub yog hais tias ib tug compound yog achiral?
Nrhiav cov pa roj carbon monoxide nrog plaub pawg sib txuas los txheeb xyuas cov chaw muaj peev xwm chiral. Kos koj cov molecule nrog wedges thiab dashes thiab kos ib daim iav duab ntawm lub molecule. Yog hais tias lub molecule nyob rau hauv daim iav duab yog tib molecule, nws yog achiral. Yog hais tias lawv yog txawv molecules, ces nws yog chiral
Yuav ua li cas ib tug geologist yuav qhia tau hais tias ib tug quav yog ib tug syncline thiab anti-line?
Geologic Structures (Part 5) Anticlines yog folds nyob rau hauv uas txhua ib nrab ntawm cov quav dips deb ntawm lub crest. Synclines yog folds nyob rau hauv uas txhua ib nrab ntawm cov quav dips mus rau lub trough ntawm lub quav. Koj tuaj yeem nco qab qhov sib txawv los ntawm kev ceeb toom tias anticlines tsim "A" zoo, thiab synclines tsim hauv qab ntawm "S."
