Nyob rau hauv lub cev qhuav dej synthesis cov tshuaj tiv thaiv (Daim duab), cov hydrogen ntawm ib lub 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.
Ib yam li ntawd, lub cev qhuav dej synthesis yog dab tsi?
Lub cev qhuav dej synthesis yog txheej txheem ntawm kev koom ua ke ob lub molecules, los yog cov tebchaw, ua ke tom qab tshem tawm cov dej. Thaum koj pom lo lus lub cev qhuav dej , thawj yam uas yuav los rau hauv siab yog 'poob dej' lossis 'tsis muaj dej. Lub cev qhuav dej synthesis yog cais raws li hom tshuaj tiv thaiv.
Ib sab saum toj, dab tsi yog lub cev qhuav dej synthesis thiab hydrolysis? Qhov txawv ntawm Lub cev qhuav dej synthesis thiab hydrolysis yog hais tias nyob rau hauv ib tug, bonds raug tsim, thaum nyob rau hauv lwm yam bonds raug puas tsuaj. Lub cev qhuav dej synthesis bonds molecules ua ke los ntawm kev tshem dej. Hauv hydrolysis , dej yog ntxiv rau cov molecules thiaj li yaj cov bonds.
Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog cov reactants ntawm lub cev qhuav dej synthesis cov tshuaj tiv thaiv?
Lub cev qhuav dej synthesis yog tshuaj tshuaj tiv thaiv nyob rau hauv uas ib los yog ntau molecules ntawm dej raug tshem tawm ntawm lub reactants los tsim cov khoom tshiab. Cov no cov tshuaj tiv thaiv tuaj yeem tshwm sim thaum ib qho ntawm reactants muaj ib pawg hydroxyl (OH) uas tuaj yeem cleaved, yog li tsim cov hydroxide ion tsis zoo (OH) -).
Puas yog cov tshuaj tiv thaiv condensation zoo ib yam li cov tshuaj tiv thaiv lub cev qhuav dej?
Thaum condensation tshuaj tiv thaiv , ob lub molecules ua ke los tsim ib qho molecule nrog kev poob ntawm ib qho me me molecule; hauv lub cev qhuav dej , qhov no ploj molecule yog dej.

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
Qhov twg hauv qab no zoo tshaj plaws sawv cev rau qhov sib npaug molecular rau cov tshuaj tiv thaiv ntawm aqueous ammonia nrog sulfuric acid?
Nqe Lus Nug: Qhov Sib npaug Sib npaug rau Kev Ua Haujlwm Ntawm Aqueous Sulfuric Acid Nrog Aqueous Ammonia yog 2NH3 (aq) + H2SO4 (aq) --> (NH4) 2SO4 (aq) A
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
