Synthesis vs Decomposition
Qhov sib txawv ntawm kev sib txuas thiab kev sib cais muaj qhov muaj txiaj ntsig zoo tshaj plaws vim tias kev sib xyaw thiab kev sib cais yog ib qho tseem ceeb tshaj plaws ntawm cov tshuaj tiv thaiv uas tshwm sim hauv qhov xwm txheej. Cov tshuaj tiv thaiv tshuaj yog txhais tau tias yog tsim los yog rhuav tshem cov tshuaj sib txuas ntawm cov atoms los tsim cov kev sib txuas tshiab ntawm atoms. Cov atoms lossis kev sib xyaw ntawm cov atoms koom nrog cov tshuaj tiv thaiv yog hu ua reactants thiab cov khoom tsim tshiab yog hu ua cov khoom. Tag nrho cov tshuaj tiv thaiv tshwm sim hauv cov kab mob lom neeg tau muab faib ua plaub hom; Synthesis reactions, decomposition reactions, exchange reactions, thiab reversible reactions. Hauv kab lus no, qhov sib txawv ntawm kev sib xyaw thiab kev sib cais yuav tau tham dav dav.
Dab tsi yog Synthesis?
Ib synthesis txhais tau tias yog txheej txheem ntawm kev tsim cov ntawv cog lus tshiab ntawm cov reactants los tsim cov khoom tshiab. Cov khoom tsim tshiab yog txawv kiag li los ntawm cov reactants ntawm cov tshuaj tiv thaiv. Cov tshuaj tiv thaiv synthesis yooj yim tuaj yeem sau tau raws li hauv qab no.
A + B → AB
Hauv qhov piv txwv no, cov reactants yog A thiab B thiab cov khoom yog AB. Hauv cov txheej txheem lom neeg, cov tshuaj synthesis yog qhov tseem ceeb rau kev loj hlob ntawm lub cev thiab kho cov ntaub so ntswg puas. Qhov tseem ceeb ntawm kev sib txuas yog tsim cov ntawv cog lus tshiab thiab nws ib txwm xav tau lub zog. Lub cev cov tshuaj tiv thaiv synthesis yog sib sau ua ke hu ua anabolism.
Dab tsi yog Decomposition?
Decomposition yog tus txheej txheem ntawm kev rhuav tshem cov ntawv cog lus nyob rau hauv cov reactants kom tau txais cov khoom tshiab. Raws li kev txhais, lub ntsiab yuav tsum tau ntawm lub decomposition yog rhuav cov tshuaj bonds. Ib qho yooj yim decomposition tshuaj tuaj yeem sau tau raws li hauv qab no.
AB → A + B
Ntawm no, cov reactant yog AB thiab cov khoom yog A thiab B. Tsis zoo li cov synthesis, decomposition reactions ua rau lub emission ntawm lub zog. Yog li ntawd, cov tshuaj tiv thaiv decomposition hauv lub cev feem ntau tshwm sim rau lub hom phiaj ntawm kev tsim lub zog. Piv txwv li, cov hlwb hauv lub cev tau txais lub zog los ntawm decomposition ntawm qabzib (reactant) ua rau dej thiab carbon dioxide ua cov khoom. Lub zog tso tawm los ntawm kev rhuav tshem cov ntawv cog lus ntawm cov piam thaj molecules yog siv rau hauv txhua txoj haujlwm ntawm tes. Lub cev cov tshuaj tiv thaiv decomposition yog sib sau ua ke hu ua catabolism.
Dab tsi yog qhov sib txawv ntawm Synthesis thiab Decomposition?
• Decomposition is the opposite of synthesis.
• Synthesis yog cov txheej txheem ntawm kev tsim cov ntawv cog lus tshiab ntawm cov reactants los tsim cov khoom tshiab, whereas decomposition yog kev tawg ntawm cov tshuaj bonds hauv reactants los tsim cov khoom sib txawv.
• Synthesis xav tau lub zog, whereas decomposition tso zog.
• Cov tshuaj tiv thaiv decomposition yog sib sau ua ke hu ua catabolism, whereas synthesis reactions hu ua anabolism.
• Synthesis koom nrog hauv kev loj hlob ntawm lub cev thiab kho cov ntaub so ntswg hauv lub cev. Decomposition tshwm sim thaum lub sij hawm zom cov zaub mov.
