Dr. Haxton hais rau nws chav kawm tias a dej molecule tau ua 4 hydrogen bonds , tag nrho cov nyob rau hauv tib lub dav hlau raws li peb atoms.
Ib yam li ntawd, nws raug nug, pes tsawg atoms hauv cov molecule hauv qab no tuaj yeem koom nrog hydrogen bonding nrog dej?
Txhua dej molecule tau form ob hydrogen bonds koom nrog lawv hydrogen atoms ntxiv ob ntxiv hydrogen bonds siv cov hydrogen atoms txuas rau cov neeg nyob sib ze dej molecules . plaub no hydrogen bonds optimally teem lawv tus kheej tetrahedrally nyob ib ncig ntawm txhua dej molecule raws li pom hauv cov dej khov zoo tib yam (saib txoj cai).
Ib yam li ntawd, yuav ua li cas yog tias dej tsis tsim hydrogen bonds? Hydrogen bonds ua kom qhov txo qis ntawm qhov kub siab tshaj plaws hauv lub cev loj ntawm dej . Txawm li cas los, tsis muaj hydrogen bonds , dej hauv dej hiav txwv thiab pas dej yuav pib sai sai vim qhov poob ntawm qhov kub npau npau - ua rau muaj teeb meem loj rau lub neej hauv ntiaj teb.
Tsis tas li ntawd, hom ntawv cog lus twg yog dej?
Dej yog ib tug polar molecule A dej molecule yog tsim thaum ob atoms ntawm hydrogen daim ntawv cog lus covalently nrog ib tug atom ntawm oxygen. Hauv covalent daim ntawv cog lus electrons sib koom ntawm atoms. Hauv dej kev sib koom tsis sib npaug. Cov pa oxygen atom nyiam cov electrons ntau dua li cov hydrogen.
Puas yog ch4 yog hydrogen bond?
Teb thiab piav qhia: CH 4 tsis tuaj yeem tsim hydrogen bonds . Qhov no yog vim hydrogen bonds yog ib hom kev sib cuam tshuam electrostatic, uas tsuas yog ua tau nyob rau hauv molecules nyob rau hauv uas
Pom zoo:
Muaj pes tsawg lub hauv paus zoo tuaj yeem muaj qhov sib npaug?
Ib txoj hauv kev los txiav txim siab qhov siab tshaj plaws ntawm qhov zoo thiab qhov tsis zoo ntawm cov hauv paus ntsiab lus ntawm polynomial. Txij li thaum muaj peb qhov kev hloov pauv, muaj qhov siab tshaj plaws ntawm peb lub hauv paus zoo
Muaj pes tsawg atoms nyob rau hauv dej molecule?
peb atoms Hauv qhov no, pes tsawg oxygen atoms nyob rau hauv ib lub molecule ntawm dej? Cov tshuaj formula rau dej yog H 2 O uas txhais tau tias txhua molecule ntawm dej muaj 2 atom ua ntawm hydrogen (H) thiab ib atom ntawm oxygen (O).
Hauv cov molecules lom neeg twg koj tuaj yeem pom hydrogen bonds?
Hydrogen Bond Piv txwv Hydrogen bonding tshwm sim nto moo tshaj plaws ntawm cov dej molecules. Tib neeg DNA yog ib qho piv txwv nthuav ntawm hydrogen daim ntawv cog lus. Hydroflouric thiab formic acids muaj ib hom tshwj xeeb ntawm hydrogen daim ntawv cog lus hu ua symmetric hydrogen bond
Muaj pes tsawg hydrogen ions muaj nyob rau hauv ib liter dej?
Daim Npav Lub Sijhawm Thaum cov kua qaub reacts cov tebchaw twg tsim? Txhais lus ntsev thiab dej Lub sij hawm muaj pes tsawg hydrogen ions muaj nyob rau hauv ib liter dej? txhais tsis muaj; Lawv tag nrho cov hydrated Term Dab tsi yog qhov concentration ntawm hydronium ions nyob rau hauv ib tug nruab nrab tov? Lus Txhais 10^-7 M
Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
