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.
