Chav Kawm 10 Tshuaj Chemistry Cov tshuaj tiv thaiv thiab Equations. Kev sib xyaw ua ke . Kev sib xyaw ua ke . Thaum ob los yog ntau tshaj reactants undergoeschemical tshuaj tiv thaiv tsim ib yam khoom, lub cov tshuaj tiv thaiv npe kev sib xyaw ua ke i.e. A + BAB.
Ib yam li ntawd, ib tug yuav nug, dab tsi yog kev sib xyaw ua ke piav qhia nrog piv txwv?
Cov reactants, A thiab B, sib xyaw ua ke los tsim cov khoom lag luam xov xwm, AB, uas yog ib txwm ua ke. Ib piv txwv ofa ua ke cov tshuaj tiv thaiv yog thaum hydrogen thiab chlorine teb tsim hydrochloric acid: Cov subscripts inthechemical tshuaj tiv thaiv nyob rau hauv daim duab no xa mus rau lub statesofmatter.
Ib sab saum toj no, qhov kev hloov pauv hloov pauv li cas nrog piv txwv? Kev hloov pauv hloov yog achemical tshuaj tiv thaiv nyob rau hauv uas ib tug ntau reactive element displacesa lessreactive keeb los ntawm nws cov compound. Ob qho tib si hlau thiab non-metals sib koom ua ke kev hloov pauv hloov . Piv txwv : Kev tshwm sim ntawm cov ntsia hlau hlau nrog coppersulphatesolution.
Yog li ntawd, koj txhais li cas los ntawm kev sib xyaw tshuaj?
A ua ke cov tshuaj tiv thaiv, tseem hu ua asynthesisreaction hauv chemistry , yog thaum ob los yog ntau tshaj cov khoom, orreactants, ua ke nrog ib leeg los tsim ib yam khoom tshiab. Cov khoom yuav ib txwm yog ib qho sib xyaw. Muaj peb hom ua ke tshuaj tiv thaiv: Kev sib xyaw ofwoelements.
Dab tsi yog hom tshuaj tiv thaiv?
Qhov ntau hom tshuaj tiv thaiv thaj chaw ua raws li:
- Kev sib xyaw.
- Decomposition.
- Ib qho kev hloov pauv.
- Muab faib ua ob npaug.
- combustion.
- Redox.

Vim li cas cov tshuaj tiv thaiv kev zom zaub mov hu ua hydrolysis cov tshuaj tiv thaiv?
Thaum lub sij hawm zom mov, piv txwv li, decompositionreactions zom cov zaub mov loj rau hauv cov me me los ntawm kev ntxiv cov dej molecules. Hom tshuaj no hu ua hydrolysis. Raws li dej absorbs heatenergy, qee lub zog yog siv los rhuav tshem hydrogenbonds
Txoj kev faib cov ntaub ntawv twg muab cov ntaub ntawv sib npaug ntawm cov ntaub ntawv lossis cov kev tshuaj xyuas hauv txhua chav kawm cov ntaub ntawv?
Quantile. txhua chav kawm muaj cov yam ntxwv sib npaug. Ib qho kev faib tawm ntau yog zoo haum rau cov ntaub ntawv faib tawm. Quantile muab tib tus lej ntawm cov ntaub ntawv muaj nuj nqis rau txhua chav kawm
Puas yog cov tshuaj pleev xim sib xyaw cov tshuaj tiv thaiv?
Tsis yog txhua qhov kev hloov xim qhia tias muaj tshuaj lom neeg. Kev sib xyaw xim tsuas yog hloov lub cev. Tsis muaj cov khoom tshiab tsim. Vim hais tias lub cev thiab tshuaj pleev xim ntawm cov xim siv los ua xim sib txawv, tus nqi thiab qhov deb ntawm lawv mus raws li daim ntawv so ntswg sib txawv, ua rau cov xim sib txawv
Cov tshuaj tiv thaiv dab tsi yog qhov tshuaj tiv thaiv neutralization?
Neutralization yog ib hom tshuaj tiv thaiv nyob rau hauv uas muaj zog acid thiab muaj zog puag react nrog ib leeg los tsim dej thiab ntsev
Dab tsi yog tshuaj lom neeg cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv lub cev?
Qhov sib txawv ntawm cov tshuaj tiv thaiv lub cev thiab cov tshuaj tiv thaiv tshuaj yog muaj pes tsawg leeg. Hauv cov tshuaj tiv thaiv tshuaj, muaj kev hloov pauv ntawm cov tshuaj hauv nqe lus nug; nyob rau hauv ib qho kev hloov ntawm lub cev muaj qhov sib txawv ntawm qhov tsos, tsis hnov tsw, los yog cov duab yooj yim ntawm cov qauv ntawm cov teeb meem yam tsis muaj kev hloov pauv hauv cov ntsiab lus
