Qhov tseem ceeb muaj yog tsis muaj tshuaj tiv thaiv . Sodium chloride dissolves nyob rau hauv dej li sodium cations thiab chlorine anions. Yam tshuaj twg tshuaj tiv thaiv yog sawv cev los ntawm Na2CO3 2HCl-2NaCl + H20 + CO3?
Xav txog qhov no, NaCl puas cuam tshuam nrog NaOH?
Cov khoom siv tshuaj NaOH (aq) + HCl(aq) → NaCl (aq) + H2O(l) Feem ntau xws li neutralization cov tshuaj tiv thaiv yog sawv cev los ntawm ib qho yooj yim net ionic kev sib npaug : OH−(aq) + H+(aq) → H2O. Hom no tshuaj tiv thaiv tso cua sov thaum siv cov kua qaub uas muaj zog.
Qhov thib ob, NaCl cuam tshuam nrog dab tsi? Ib qho piv txwv yog qhov tshuaj tiv thaiv hauv uas sodium (Na) ua ke nrog chlorine (Cl 2) ua form sodium chloride , los yog ntsev ( NaCl ). A tshuaj tiv thaiv ntawm sodium nrog chlorine los tsim sodium chloride yog ib qho piv txwv ntawm kev sib xyaw tshuaj tiv thaiv.
Ib yam li ntawd, nws tau nug, yuav ua li cas thaum HCl reacts nrog Na2CO3?
Thaum twg hydrochloric acid (chemical formula: HCl ) reacts nrog sodium carbonate (chemical formula: Na2CO3 ), ib ob cov tshuaj tiv thaiv yuav tshwm sim, nyob ntawm seb muaj pes tsawg tus txheeb ze ntawm txhua yam tshuaj. Hauv qhov tshuaj tiv thaiv no, sodium carbonate reacts nrog tshaj hydrochloric acid los tsim sodium chloride, dej thiab carbon dioxide.
Puas yog sodium chloride ua rau cov kua qaub?
Hydrochloric acid reacts nrog sodium hydroxide tsim sodium chloride (ib ntsev) thiab dej. Sodium chloride yog tsim los ntawm Na + cations los ntawm lub hauv paus (NaOH) thiab Cl- anions los ntawm lub kua qaub (HCl). Hydrochloric acid reacts nrog ammonia los ua ammonium tshuaj chloride (ib ntsev).

Puas yog kev hloov pauv cov ciam teb puas tsuaj?
C) Transform Plate Boundaries Qhov thib peb ntawm phaj ciam teb yog qhov kev hloov pauv, qhov twg daim hlau hla dhau ib leeg yam tsis muaj kev tsim khoom lossis kev puas tsuaj ntawm crust. Cov no tuaj yeem ua rau qee qhov av qeeg ua rau muaj kev puas tsuaj loj tshaj plaws nyob rau sab av loj
Puas yog cov teb chaws zoo ib yam li daim phiaj qhia koj cov lus teb?
Continental crust tsis npog tag nrho cov saum npoo ntawm lub ntiaj teb - nruab nrab ntawm nws yog tob dej hiav txwv crust. Tectonic daim hlau (qee zaum erroneously hu ua 'continental daim hlau' yog ib feem ntawm lub ntiaj teb' Lawv yog ob yam sib txawv heev
Puas yog NaCl yog molecule lossis compound?
Sodium chloride (NaCl) yog ib qho piv txwv classic ntawm anionic compound, los yog compound tsim los ntawm ionic bonds. Dej (H2O) feem ntau hu ua molecular compound, tab sis kuj tseem hu ua covalent compound vim nws yog ib qho compound tsim los ntawm covalent bonds
Puas yog lub ntiaj teb lossis lub ntiaj teb?
Lub ntiaj teb yog ib qho chaw. Lub Ntiaj Teb yog ib lub ntiaj teb.Txawm hais tias tsis muaj kev lees paub thoob ntiaj teb cov qauv sau ntawv hais txog kev siv ntawm Lub Ntiaj Teb ua ntej tab sis nyob rau hauv feem ntau cov xwm txheej thaum taw tes rau lub ntiaj teb raws li lub npe tsim nyog peb xav siv Tus ua ntej
Dab tsi alkaline ntiaj teb hlau yog feem ntau reactive nrog dej?
Cov hlau alkali (Li, Na, K, Rb, Cs, thiab Fr) yog cov hlau reactive tshaj plaws nyob rau hauv lub sij hawm lub sij hawm - lawv tag nrho cov hnov mob heev los yog txawm explosively nrog dej txias, uas ua rau lub displacement ntawm hydrogen
