LIF: ib molecule nrog kev ua haujlwm sib txawv ntawm myeloid leukaemic cells thiab embryonic qia hlwb. Yog li, raws li ib tug xov tooj ntawm biochemical thiab biological zoo sib xws, nws yog zoo li ntawd LIF thiab DIA yog tib yam molecule.
Cov lus nug tseem yog, LiF chemistry yog dab tsi?
Lithium fluoride yog ib qho inorganic compound nrog cov tshuaj qauv LiF . Nws yog cov xim tsis muaj xim, uas hloov mus rau dawb nrog txo qis siv lead ua loj. Txawm hais tias tsis muaj ntxhiab, lithium fluoride muaj iab-saline saj.
Tsis tas li ntawd, tus nqi ntawm LiF yog dab tsi? Qhov tsis sib haum xeeb nqi qhov ceev ntawm lithium nucleus nyob rau hauv LiF ua 1,07e- piv 1,5e- hauv Li atom (piv txwv li, ib nrab ntawm tag nrho cov xov tooj hluav taws xob nqi hauv Li atom). Los ntawm txoj kev sib piv, cov tsis sib koom nqi ntawm nitrogen nuclei hauv N2 yog nce siab tshaj tus nqi atomic ntawm 3.5 e- ua 3,68e-.
Ua li no, puas yog LiF ionic lossis molecular?
LiF yog lithium fluoride. Qhov no yog ib qho piv txwv ntawm binary ionic compound, uas muaj ob lub ntsiab lus, ib qho cation thiab anion. Txij li thaum lithium, cov hlau muaj ib qho ntxiv, thiab fluoride, cov hlau tsis zoo, muaj cov nqi tsis zoo, ob qho no ions muaj nyob ua ke los ntawm ib ionic daim ntawv cog lus.
Vim li cas LiF tsis soluble hauv dej?
Vim nws cov dej tsis muaj zog thiab ib nrab covalent thiab ib nrab ionic cim LiCl yog soluble nyob rau hauv dej zoo li acetone. Hauv Lithium fluoride lub lattice enthalpy yog siab heev vim me me ntawm fluoride ions. Hauv qhov no, hydration enthalpy yog tsawg heev. Vim li no, LiF yog insoluble hauv dej.

Puas yog ib qho tsis muaj polar molecule puas muaj hydrogen bonding?
Yog hais tias lub molecule tsis yog polar, ces tsis muaj kev sib cuam tshuam dipole-dipole los yog hydrogen bonding tuaj yeem tshwm sim thiab tsuas yog ua tau intermolecular quab yuam yog lub zog van der Waals tsis muaj zog
Puas yog NaCl yog molecule lossis compound?
Sodium chloride (NaCl) yog ib qho piv txwv classic ntawm anionic compound, los yog compound tsim los ntawm ionic bonds. Dej (H2O) feem ntau hu ua molecular compound, tab sis kuj tseem hu ua covalent compound vim nws yog ib qho compound tsim los ntawm covalent bonds
Puas yog chf3 polar lossis nonpolar molecule?
Yog tias koj saib ntawm Lewis qauv rau CHF3 nws tsis tshwm sim ib qho symmetrical molecule. Ib tug polar molecule tshwm sim los ntawm qhov sib npaug / unsymmetrical sib koom ntawm valence electrons. Hauv CHF3 qhov kev sib koom tsis sib npaug thiab muaj cov net dipole. Yog li ntawd, CHF3- yog ib tug polar molecule
Puas yog fluorine gas yog molecule lossis ion?
Xav kom cov fluoride ion nyob rau hauv ib tug ionic daim ntawv cog lus nrog lithium ion, ob zaug (kom sib npaug ntawm qhov sib npaug). Fluorine nyob rau hauv nws daim ntawv yog F2, ib tug nruab nrab molecule
Puas yog codon txuas ntawm ib kawg ntawm tRNA molecule?
Nws txuas los ntawm ib kawg ntawm tRNA molecule. Nws yog lub hauv paus chav tsev ntawm cov noob caj noob ces. Nws muaj peb nucleotides. Nws yeej tsis code rau ntau tshaj ib cov amino acid
