Monomers yog ib tug neeg units uas tsim ib tug polymer. Peb ua tau txiav txim dab tsi monomer yog los ntawm thawj zaug nrhiav qhov tsawg tshaj plaws rov qab qauv. Peb ces yuav tsum tau txiav txim yog tias tag nrho cov pa roj carbon atom hauv qhov kev rov ua dua tshiab muaj octet.
Tsis tas li ntawd, dab tsi yog monomer hauv chemistry?
Monomer , ib qho molecule ntawm ib chav kawm ntawm cov tebchaw, feem ntau yog cov organic, uas tuaj yeem hnov mob nrog lwm cov molecules los tsim cov molecules loj heev, lossis polymers. Qhov tseem ceeb feature ntawm a monomer yog polyfunctionality, muaj peev xwm tsim tshuaj daim ntawv cog lus rau yam tsawg kawg yog ob leeg monomer molecules.
Ib yam li ntawd, 4 hom monomers yog dab tsi? Muaj plaub lub ntsiab monomers: amino acids, nucleotides, monosaccharides thiab fatty acids. Cov monomers tsim cov hom yooj yim ntawm macromolecules: cov proteins , nucleic acids, carbohydrates thiab lipids.
Qhov thib ob, cov piv txwv ntawm monomers yog dab tsi?
Glucose, vinyl chloride, amino acids, thiab ethylene yog piv txwv ntawm monomers . Txhua monomer tuaj yeem txuas rau ntau txoj hauv kev los tsim ntau yam polymers. Nyob rau hauv cov ntaub ntawv ntawm qabzib, rau piv txwv , glycosidic bonds tuaj yeem txuas cov suab thaj cov monomers los tsim cov polymers xws li glycogen, starch, thiab cellulose.
Dab tsi yog monomer ntawm carbohydrate hu ua thiab koj tuaj yeem txheeb xyuas tau li cas?
Carbohydrates yog ib qho ntawm plaub lub hauv paus cov macromolecules ntawm lub neej. Lawv yog cov polymer ua los ntawm monomers hu ua monosaccharides . Cov tsev thaiv no yog cov suab thaj yooj yim, piv txwv li, qabzib thiab fructose . Ob monosaccharides kev sib txuas ua ke ua rau lub disaccharide.

Yuav ua li cas koj txheeb xyuas lub kaum ntse ntse?
Qhov kev sib tshuam ntawm ob kab tau tsim lub kaum sab xis. Lub kaum sab xis yog ob lub kaum sab xis uas muaj kev sib raug zoo tshwj xeeb. Lub kaum sab xis khub hauv daim duab no muaj qhov ntsuas uas sib npaug 180 ° uas yog qhov ntsuas ntawm lub kaum sab xis. Lub kaum sab xis uas muaj qhov sib npaug ntawm 180 ° yog hu ua cov ces kaum ntxiv
Yuav ua li cas hom ntawm cov khoom raug txheeb xyuas los ntawm nws lub cev thiab tshuaj lom neeg lub zog?
Intensive zog, xws li ceev thiab xim, tsis nyob ntawm seb tus nqi ntawm cov khoom tam sim no. Lub cev lub cev tuaj yeem ntsuas yam tsis tau hloov cov khoom siv tshuaj lom neeg. Cov khoom siv tshuaj muaj peev xwm ntsuas tau los ntawm kev hloov cov tshuaj lom neeg tus kheej
Yuav ua li cas koj txheeb xyuas ib qho kev tawm tsam ua khub?
Txheeb xyuas ob khub ntawm kev ua-kev tawm dag zog. Siv cov cim 'ko taw A', 'ko taw C', thiab 'pob B' hauv koj cov lus. Nyem lub khawm kom pom cov lus teb. Thawj khub ntawm kev txiav txim siab-kev quab yuam ua khub yog: ko taw A thawb pob B mus rau sab xis; thiab pob B thawb ko taw A mus rau sab laug
Yuav ua li cas koj txheeb xyuas lub metalloid?
Khoom siv: Germanium; Silicon; Tellurium; Boron
Yuav ua li cas koj txheeb xyuas lub pob zeb igneous?
Cov kauj ruam hauv Kev Txheeb Xyuas: Txiav txim siab cov xim (qhia cov ntxhia muaj pes tsawg leeg) Txiav txim siab qhov kev ntxhib los mos (qhia txog keeb kwm txias) Phaneritic = cov nplej loj. Aphanitic = me nplej (me me dhau los txheeb xyuas qhov muag tsis pom) Porphyritic = cov nplej zoo sib xyaw nrog cov nplej loj. Vesicular = qhov. Glassy = iav zoo li
