Qee cov polymers yog tsim los ntawm condensation polymerization. Nyob rau hauv condensation polymerization, ib tug me me molecule yog tsim raws li ib tug los ntawm cov khoom txhua lub sij hawm ib daim ntawv cog lus tsimntawm ob monomers. Cov molecule me no feem ntau yog dej. Ib qho piv txwv ntawm condensation polymer yog nylon.
Dab tsi yog ob lub monomers rau lub condensation polymer?
A polyester cov ntaub ntawv los ntawm ob hom monomers: ib 'dicarboxylic acid' uas muaj ob pawg carboxylic acid, - COOH . a 'diol' uas muaj ob pawg cawv, -OH.
Dab tsi yuav tsum muaj ob lub monomers muaj sib xws rau condensation polymerization tshwm sim?
Ntxiv rau polymerization, cov monomers yuav tsum muaj C=C ob daim ntawv cog lus. Txawm li cas los xij, hauv condensation polymerization, cov monomers tsis xav tau C=C ob daim ntawv cog lus tab sis lawv xav tau ob pawg ua haujlwm.
YPuas condensation ua ke polymers los ua monomers?
Muaj ob peb txoj hauv kev monomers ua ke los ua cov polymers ntawm cov yas. Hauv cov tshuaj tiv thaiv condensation, ob lub molecules ua ke nrog qhov poob ntawm cov molecule me, feem ntau yog dej, cawv lossis kua qaub. …
Puas cov tshuaj tiv thaiv condensation koom nrog monomers?
Macromolecules yog tsim los ntawm ib chav tsev hu ua monomers uas tau koom nrog covalent bonds los tsim cov polymers loj. … Ib lub monomer koom nrog lwm tus monomer nrog kev tso tawm ntawm cov dej molecule, uas ua rau tsim kom muaj covalent daim ntawv cog lus. Cov tshuaj tiv thaiv no yog hu ua dehydration lossis condensation reactions.

Nyob rau hauv evaporative condenser lub condensation ntawm chav ua tiav?
15.9, cua yog ib txhij tshuab thoob plaws lub condenser coil, ua rau ib feem me me ntawm cov dej rov ua kom evaporate. Qhov no evaporation tshem tawm heat ntawm lub kauj, yog li txias thiab condensing lub vapor. Daim duab 15.9. Schematic ntawm evaporative condenser .
Yuav tsum ob glazing tau condensation nyob rau hauv?
Koj ob chav glazed qhov rais yuav tsum tsis txhob muaj condensation ntawmcov iav nto sab hauv - ob qhov chaw uas tuaj rau hauv kev sib cuag nrog huab cua nyob nruab nrab ntawm ob lub iav ntawm cov iav insulated, los yog IGU. Yog tias koj pom cov dej noo ntawm no, koj muaj teeb meem nrog koj ob lub glazing .
Condensation polymerization yog dab tsi?
Condensation polymers yog txhua yam polymers tsim los ntawm cov tshuaj tiv thaiv condensation-qhov twg cov molecules koom ua ke-poob me me molecules li byproducts xws li dej los yog methanol. txhais li cas los ntawm condensation polymerization?
Nyob rau hauv teb rau qhov tuaj txog ntawm acidic chyme nyob rau hauv lub duodenum?
Pab plab hnyuv . theem plab hnyuvtshwm sim hauv duodenum raws li cov lus teb rau cov chyme tuaj txog, thiab nws txo qis kev ua pa ntawm plab los ntawm cov tshuaj hormones thiab lub paj hlwb reflexes . Yuav ua li cas teb rau qhov tuaj txog ntawm acidic chyme hauv duodenum?
Thaum nucleotide monomers koom ua ke?
Nucleotides yog cov monomers uas koom ua ke tsim cov qauv ntawm RNA thiab DNA, nrog rau muab lub zog hauv cov metabolism. (C), Guanine (G), Adenine (A), Thymine (T), thiab Uracil (U). Ib qho phosphate yog ntsev uas muaj phosphorus thiab oxygen txuas rau ib lossis ntau dua alkyl lossis aryl molecule .
