Solubility yog qhov ntsuas ntawm qhov ntau npaum li cas yam khoom yuav yaj nyob rau hauv ib tug muab ntim ntawm a ua kua . Cov ua kua hu ua kuab tshuaj. Lub solubility ntawm ib tug roj nyob ntawm siab thiab kub.
Yog li ntawd, lo lus scientific siv los piav txog ib yam khoom uas yuav tsis yaj?
Hauv qhov piv txwv no, qab zib yog cov kua dej thiab dej yog qhov hnyav. Ib tug sib tov uas a tshuaj tsis yaj hauv dej yog hu ua suspension thiab yam khoom hais tias yog insoluble.
Tom qab, lo lus nug yog, dab tsi cov khoom yog soluble nyob rau hauv dej? Ionic tshuaj yog feem ntau soluble feem ntau nyob rau hauv polar solvents; qhov siab dua lub lattice zog, lub polar ntau dua qhov hnyav yuav tsum tau kov yeej lub lattice zog thiab yaj tus yam khoom.
Ib yam li ntawd, ib tug yuav nug, lub sij hawm twg yog muab rau cov khoom uas tuaj yeem yaj hauv cov kua?
A khoom dissolves nyob rau hauv ib tug kua thaum nws tov tag nrog cov ua kua . Tej yam uas yaj hu ua solutes thiab ua kua hauv lawv yaj yog hu ua cov kuab tshuaj los tsim cov tshuaj. Cov khoom muaj zog polar yooj yim nyiam cov dej molecules. Cov dej molecules nyob ib puag ncig ntawm cov kuab tshuaj.
Koj hu dab tsi uas yaj hauv dej?
Dej yog ib qho hnyav, txhais tau tias nws yog kua uas yaj tshuaj. Ib yam khoom ntawd yaj yog hu ua lub solute, thiab qhov sib tov tsim thaum cov kuab tshuaj thiab solute tag ua ke thiab ua tsis cais yog hu ua kev daws teeb meem.

Yog vim li cas magnesium nyob rau lub sij hawm 3 ntawm lub sij hawm?
Cov qauv ntawm cov khoom hloov pauv thaum koj mus hla lub sijhawm. Thawj peb yog hlau, silicon yog loj covalent, thiab tus so yog cov molecules yooj yim. Sodium, magnesium thiab aluminium tag nrho muaj cov qauv hlau. Nyob rau hauv magnesium, ob qho tib si ntawm nws sab nrauv electrons koom nrog, thiab nyob rau hauv txhuas tag nrho peb
Lub square ntawm lub sij hawm lub sij hawm hu ua dab tsi?
Lub ib hlis ntuj 24, 2016. Txhua square ntawm lub periodic rooj muab yam tsawg kawg nkaus lub npe ntawm lub caij, nws cov cim, atomic tooj thiab txheeb ze atomic mass (atomic hnyav)
Lub sij hawm twg yog californium nyob rau hauv lub sij hawm?
Cov khoom no yog ib qho khoom. Californium tau muab cais ua ib feem ntawm Actinide series raws li ib qho ntawm 'Rare Earth Elements' uas tuaj yeem nyob hauv Pawg 3 cov ntsiab lus ntawm Lub Sij Hawm Lub Sijhawm thiab hauv 6th thiab 7th lub sijhawm. Lub Ntiaj Teb Rare Elements yog ntawm Lanthanide thiab Actinide series
Lub sij hawm ntawm lub sij hawm geology yog dab tsi?
Cov sij hawm no tsim cov ntsiab lus ntawm kev sib faib ntawm cov geologists tau faib lub ntiaj teb keeb kwm. Eons thiab eras yog cov subdivisions loj dua lub sij hawm thaum lub sij hawm lawv tus kheej yuav muab faib ua epochs thiab hnub nyoog. Cov pob zeb tsim nyob rau hauv ib lub sij hawm yog nyob rau hauv lub stratigraphic unit hu ua ib tug system
Cov kab ntsug nyob rau hauv lub sij hawm lub sij hawm sawv cev li cas?
Cov kab ntsug ntawm lub sij hawm teev npe hu ua pab pawg lossis tsev neeg vim lawv cov tshuaj lom neeg zoo sib xws. Txhua tus tswv cuab ntawm tsev neeg ntawm cov ntsiab lus muaj tib tus lej ntawm valence electrons thiab cov khoom siv tshuaj zoo sib xws. Cov kab kab rov tav ntawm lub rooj ntu ntu yog hu ua lub sijhawm
