Raws li nouns qhov txawv ntawm copolymer thiab heteropolymer yog tias copolymer yog (chemistry) ib tug polymer muab los ntawm ntau tshaj ib hom ntawm monomer thaum heteropolymer yog (chemistry) ib tug polymer derived los ntawm ob los yog ntau tshaj sib txawv (tab sis feem ntau zoo sib xws) hom monomer.
YPuas yog homopolymer lossis copolymer?
Yog tias ib lub polymer muaj tib hom monomers ces nws hu ua ib tug homopolymer, thaum lub polymer uas muaj ntau tshaj ib hom monomers hu ua copolymer.
lwm lub npe ntawm copolymer yog dab tsi?
Lub polymerization ntawm monomers rau hauv copolymer yog hu ua copolymerization. Copolymers tau los ntawm copolymerization ntawm ob hom monomer qee zaum hu ua bipolymersCov uas tau los ntawm peb thiab plaub monomers yog hu ua terpolymer thiab quaterpolymer, feem.
homopolymer thiab copolymer yog dab tsi?
Homopolymer yog tsim los ntawm ib hom monomer nkaus xwb. Nyob rau hauv lub rov ua qauv chav tsev ntawm ib homopolymer, tsuas yog ib hom monomer unit yog tam sim no. Ntawm qhov tod tes, copolymer yog tsim los ntawm ob (lossis ntau dua) hom monomer units. … Polythene, Teflon, PAAN thiab nylon-6 yog qee qhov piv txwv ntawm homopolymers.
Koj txhais li cas los ntawm copolymer?
Ib copolymer yog a polymer tsim thaum ob (lossis ntau dua) ntau hom monomer txuas rau tib lub polymer saw, tsis zoo li homopolymer uas tsuas yog siv ib lub monomer xwb..

Puas yog yug thiab moles yog tib yam?
Moles thiab birthmarks tsis tas yuav yog ib qho tib si, tab sis lawv tuaj yeem yooj yim tsis meej pem vim tias mole tuaj yeem tshwm sim thaum yug. Qee tus kws kho mob xav tias mole yog "kev zoo nkauj" vim nws yog thaj chaw pigmentated.
Puas yog lub tesseract thiab lub pob zeb qhov chaw yog tib yam?
Lub Tesseract, tseem hu ua lub voos xwmfab, yog lub pob zeb crystalline zoo li lub nkoj ntimrau lub Pob Zeb Space, ib qho ntawm rau Lub Pob Zeb Infinity uas ua rau lub ntiaj teb thiab muaj lub zog tsis muaj kev txwv.. Nws tau siv los ntawm ntau yam kev vam meej thaum ub ua ntej los rau hauv Asgardian tes, khaws cia hauv Odin's Vault .
Puas muaj ntau yam thiab ntau yam zoo ib yam?
Kev sib sib zog nqus-qhov sib txawv ntawm qhov nqaim-ntawm cov khoom lag luam txhais tau hais tias tus neeg muag khoom nqa ntau qhov sib txawv ntawm ib yam khoom. Ntau yam-qhov sib txawv ntawm qhov nqaim-ntawm cov khoom txhais tau tias tus neeg muag khoom nqa ntau yam khoom sib txawv.
Puas yog lub kaus mom thiab lub kaus mom yog tib yam?
yog tias helm yog (nautical) lub steering apparatus ntawm lub nkoj, tshwj xeeb tshaj yog lub tiller los yog lub log thaum lub rudder yog (nautical) ib tug underwater vane siv rau steer lub nkoj lub rudder. yog tswj los ntawm lub log, tiller los yog lwm yam khoom siv (hnub no cov hlab ntsha tuaj yeem tswj tau txawm tias muaj lub joystick lossis lub autopilot) .
Puas yog ntau yam tib yam li txhais tau?
Qhov txhais tsis yog ib tus lej tag nrho. Qhov ntau yog qhov txawv ntawm tus lej loj tshaj thiab tus lej tsawg tshaj . IS range also mean? Qhov txawv ntawm qhov qis tshaj thiab qhov siab tshaj plaws. Hauv {4, 6, 9, 3, 7} tus nqi qis tshaj yog 3, thiab qhov siab tshaj plaws yog 9, yog li qhov ntau yog 9 − 3=6.
