Ntsev ( sodium chloride ) yog tsim los ntawm qhov zoo sodium ions sib txuas rau qhov tsis zoo chloride ions. Dej tau yaj ntsev vim tias qhov zoo ntawm cov dej molecules nyiam cov chloride ions tsis zoo thiab qhov tsis zoo ntawm cov dej molecules nyiam cov sodium ions zoo.
Tib neeg kuj nug, NaCl yaj ua li cas?
Sodium chloride ( NaCl ) yaj thaum dej molecules tsis tu ncua tua cov NaCl siv lead ua, rub tawm tus kheej sodium (Na+) thiab chloride (Cl–) cov. Qhov no nonstop nres txuas ntxiv mus txog rau tag nrho NaCl crystal disintegrates.
Ib sab saum toj no, vim li cas cov ntsev zoo li NaCl nyob ua ke? Raws li tau hais ua ntej, tag nrho cov zaub mov tau faib ua ntsev yog tuav ua ke los ntawm ionic bonds. Cov kub yog qhov tshwm sim ntawm ib qho tshwj xeeb atomic kev npaj ntawm sodium thiab chlorine ions, uas yog Qhov tshwm sim ntawm ob qho tib si ionic nqi thiab ionic radii.
Ntxiv rau qhov no, yuav ua li cas thaum ntsev yaj?
Thaum twg ntsev yog tov nrog dej, lub ntsev dissolves vim covalent bonds ntawm cov dej muaj zog tshaj cov ionic bonds nyob rau hauv lub ntsev molecules. Cov dej molecules rub cov sodium thiab chloride ions sib nrug, rhuav tshem cov ionic daim ntawv cog lus uas tuav lawv ua ke.
Puas yog NaCl soluble hauv dej?
NaCl yog obviously soluble nyob rau hauv dej . NaCl yog aka hom ntsev thiab thaum nws dissolves nyob rau hauv dej nws yog hu ua ntsev dej uas koj tau hnov ua ntej. FYI, feem ntau ntawm sodium ntsev yaj nkag hauv dej vim siab hydration zog ntawm sodium ions.

Vim li cas ntoo hlawv es tsis txhob yaj?
Uas feem ntau ntawm cov cellulose, lignin, dej, thiab ntau yam ntaub ntawv, ntoo muaj cov saw ntev organic molecules uas decompose rau hauv cov khoom xws li charcoal, dej, methanol, thiab carbon dioxide thaum cua sov. Raws li qhov tshwm sim ntawm cov tshuaj, irreversible tawg ntawm nws cov Cheebtsam, wooddoes tsis yaj
Yuav ua li cas yog tag nrho yaj yaj nyob rau hauv lub pas dej ua ke?
Koj cov khoom tawg tag nrho, lossis TDS, tus nqi yog qhov ntsuas ntawm tag nrho cov khoom uas yaj hauv koj lub pas dej. Cov pas dej da dej yuav tsum muaj qhov siab tshaj TDS tus nqi ntawm ib ncig ntawm 1,500 txog 2,000 ppm. Piv txwv li, cov dej haus tuaj yeem muaj qhov siab tshaj TDS tus nqi ntawm 500 ppm raws li EPA
Vim li cas ammonium nitrate yaj hauv dej endothermic?
Ntxiv Ammonium Nitrate rau Dej Thaum nws los rau hauv dej, cov polar dej molecules cuam tshuam nrog cov ions thiab thaum kawg ua rau lawv tawg. Cov tshuaj tiv thaiv endothermic ntawm kev sib xyaw ntawm ammonium nitrate thiab dej tshem tawm cov cua sov los ntawm ib feem ntawm lub cev, 'txias' qhov chaw mob
Vim li cas cov xim cuam tshuam pom tseeb rau cov yeeb yaj kiab nyias dua li cov yeeb yaj kiab tuab?
Kev cuam tshuam ntawm lub teeb los ntawm sab sauv thiab sab qis ntawm cov xab npum lossis cov tshuaj ntxuav tes yog tshwm sim. Vim li cas cov xim cuam tshuam pom tseeb rau cov yeeb yaj kiab nyias dua li cov yeeb yaj kiab tuab? Vim yog kev cuam tshuam yoj, zaj duab xis ntawm cov roj ntawm dej hauv lub hnub ci pom tau tias daj rau cov neeg soj ntsuam ncaj qha saum lub dav hlau
Yuav ua li cas yog vim li cas vim li cas lub epigenome hloov?
Kev ua neej nyob thiab ib puag ncig (xws li kev haus luam yeeb, noj zaub mov thiab kab mob sib kis) tuaj yeem ua rau tus neeg muaj kev ntxhov siab uas ua rau muaj tshuaj lom neeg. Cov lus teb no, dhau los, feem ntau ua rau muaj kev hloov pauv hauv epigenome, qee qhov tuaj yeem ua rau puas tsuaj
