Magnesium chloride yog lub npe rau cov tshuaj sib xyaw nrog cov mis MgCl2 thiab nws ntau yam hydratesMgCl2(H2O)x. Cov ntsev no yog cov ionic halides, uas yog soluble hauv dej. Cov hydratedmagnesium chloride tuaj yeem muab rho tawm los ntawm brine lossis dej hiav txwv.
Yog li ntawd, cov npe ntawm magnesium chlorides ions yog dab tsi?
- 232-094-6 [PEB]
- 7786-30-3 [NWS]
- Additive Screening Solution 22/Kit-No 78374.
- Chloride, Magnesium.
- Dichlorure de Magnesium [Fabkis] [ACD/IUPAC Lub Npe]
- Magnesium chloride [Wiki]
- Magnesium choroid.
- Magnesium dichloride [ACD/IUPAC Lub Npe]
Tsis tas li ntawd, yam khoom twg yog SiO2? Network crystalline solids muaj cov atoms uas tuav ua ke los ntawm covalent bonds. Lawv yog cov nyuaj heev, muaj cov ntsiab lus melting siab thiab tsis zoo conductors ntawm tshav kub thiab hluav taws xob. Qee qhov paub zoo tshaj plaws crystallinesolids-tshwj xeeb yog quartz ( SiO 2 ) thiab pob zeb diamond(C)-poob hauv lub network categorization.
Tib neeg kuj nug tias, 5 hom khib nyiab yog dab tsi?
Muaj plaub ntau hom ntawm crystalline cov khoom khib nyiab : molecular cov khoom khib nyiab , network cov khoom khib nyiab , ionic cov khoom khib nyiab , thiab metallic cov khoom khib nyiab . A cov khoom atomic-theem qauv thiab muaj pes tsawg leeg txiav txim siab ntau yam ntawm nws cov macroscopic zog, xws li, piv txwv li, hluav taws xob thiab heatconductivity, ntom, thiab solubility.
Tus nqi ntawm MgCl2 yog dab tsi?
Magnesium tsim ib qho zoo ion (cation) nrog 2+ nqi thiab chlorine tsim ib qho tsis zoo ion (anion) nrog 1- nqi . Yog li ob chlorine anions tsim ib daim ntawv cog lus ionic nrog onemagnesium cation rau daim ntawv MgCl 2 , ib tug nruab nrab chemicalcompound.

Dab tsi yog 5 yam khoom ntawm cov khoom?
Cov khoom uas pom tau tias tuaj yeem tshawb pom nrog tsib qhov kev xav muaj xws li cov duab, xim, kev ntxhib los mos, hardness, luster, buoyancy, tsw, thiab saj. Cov khoom ntsuas muaj xws li qhov loj, ntim, qhov hnyav, qhov hnyav, qhov ntom, thiab qhov kub thiab txias
Yuav ua li cas koj thiaj paub tias ib yam dab tsi yog ib yam khoom dawb huv los yog sib tov?
1. Cov tshuaj dawb huv tsis tuaj yeem muab cais ua lwm yam teeb meem, thaum sib xyaw yog sib xyaw ntawm ob lossis ntau dua cov khoom ntshiab. 2. Cov khoom ntshiab muaj lub cev tsis tu ncua thiab tshuaj lom neeg, thaum cov khoom sib xyaw muaj qhov sib txawv ntawm lub cev thiab tshuaj lom neeg (piv txwv li, qhov kub thiab txias)
Dab tsi yog 4 yam khoom ntawm ib qho khoom?
Muaj plaub hom crystalline solids: molecular solids, network solids, ionic solids, thiab metallic solids. Ib qho khoom ntawm cov qauv atomic-theem thiab muaj pes tsawg leeg txiav txim siab ntau yam ntawm nws cov khoom macroscopic, xws li, piv txwv li, hluav taws xob thiab hluav taws xob conductivity, ntom, thiab solubility
Cov khoom twg yog cov piv txwv ntawm cov khoom siv tshuaj xyuas txhua yam uas siv?
Piv txwv ntawm cov khoom siv tshuaj muaj xws li flammability, toxicity, acidity, reactivity (ntau hom), thiab kub ntawm combustion. Hlau, piv txwv li, ua ke nrog oxygen nyob rau hauv lub xub ntiag ntawm dej los ua xeb; chromium tsis oxidize (Daim duab 2)
Yam khoom twg ua rau hluav taws xob hauv ob qho tib si khoom thiab molten?
Cov delocalized electrons no muaj nyob rau hauv ob qho tib si ib qho khoom thiab molten, yog li sodium tuaj yeem ua hluav taws xob hauv ob lub xeev. Sodium iodide yog heteroatomic, thiab electronegativity sib txawv ntawm sodium thiab iodide ua rau lawv cov nyiaj ionic. Ionic compounds tsim qhov hu ua crystal lattice qauv
