A synthesis cov tshuaj tiv thaiv yog hom tshuaj tiv thaiv nyob rau hauv uas ntau reactants ua ke los ua ib yam khoom. Synthesis cov tshuaj tiv thaiv tso tawm lub zog nyob rau hauv daim ntawv ntawm tshav kub thiab lub teeb, yog li lawv yog exothermic. Ib qho piv txwv ntawm a synthesis cov tshuaj tiv thaiv yog tsim cov dej los ntawm hydrogen thiab oxygen.
Xav txog qhov no, cov piv txwv ntawm cov tshuaj tiv thaiv synthesis yog dab tsi?
Ib qho tshuaj tiv thaiv synthesis tshwm sim thaum ob los yog ntau dua reactants sib xyaw ua ib yam khoom. Cov tshuaj tiv thaiv no yog sawv cev los ntawm cov kab zauv dav dav: A + B → AB. Ib qho piv txwv ntawm cov tshuaj tiv thaiv synthesis yog kev sib xyaw ua ke sodium (Na) thiab chlorine (Cl) los tsim sodium chloride (NaCl).
Tom qab ntawd, lo lus nug yog, dab tsi yog qhov kev sib txuas hauv kev sau ntawv? A synthesis yog ib qho kev sib tham uas sau los ntawm ib lossis ntau qhov chaw. Nws ua raws li qhov koj muaj peev xwm sau cov syntheses nyob ntawm koj lub peev xwm los txheeb xyuas kev sib raug zoo ntawm cov chaw - sau ntawv, kab lus, ntawv tseeb, thiab cov ntawv tsis sau, xws li kev qhuab qhia, kev xam phaj, kev soj ntsuam.
Dab tsi yog txhais los ntawm chemical synthesis?
Tshuaj synthesis , kev tsim kho ntawm complex tshuaj cov sib xyaw ua ke los ntawm cov yooj yim. Nws yog cov txheej txheem uas ntau yam tseem ceeb rau lub neej niaj hnub tau txais. Nws yog siv rau txhua yam ntawm tshuaj cov tshuaj, tab sis feem ntau cov syntheses yog cov organic molecules.
Dab tsi yog synthesis thiab piv txwv?
npe. Synthesis txhais tau tias yog kev sib txuas ntawm ntau qhov sib txawv lossis cov tswv yim los ua ib lub tswv yim tshiab lossis kev xav. Ib piv txwv ntawm synthesis yog thaum koj nyeem ob peb phau ntawv thiab siv tag nrho cov ntaub ntawv los ua cov thesis ntawm qhov kev kawm.

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
Dab tsi cov tshuaj tiv thaiv sawv cev rau lub cev qhuav dej synthesis?
Nyob rau hauv lub cev qhuav dej synthesis cov tshuaj tiv thaiv (Daim duab), cov hydrogen ntawm ib tug monomer ua ke nrog cov hydroxyl pawg ntawm lwm monomer, tso ib tug molecule ntawm dej. Nyob rau tib lub sijhawm, cov monomers sib koom electrons thiab tsim covalent bonds. Raws li cov monomers ntxiv koom nrog, cov saw hlau ntawm kev rov ua dua monomers tsim ib lub polymer
Ob lub tebchaw puas tuaj yeem siv los ua cov tshuaj reactants rau cov tshuaj tiv thaiv synthesis?
7. Ob lub ntsiab lus puas tuaj yeem siv los ua cov reactants rau cov tshuaj tiv thaiv synthesis? Yog tias muaj, muab tsawg kawg ib qho piv txwv los ntawm Qauv 1 los txhawb koj cov lus teb. Ob lub ntsiab lus thiab cov tebchaw tuaj yeem pom hauv cov khoom ntawm cov tshuaj tiv thaiv decomposition
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
