A homologous series nyob rau hauv cov organic chemistry yog ib pawg ntawm cov organic tebchaw (cov tshuaj uas muaj C atoms) uas sib txawv ntawm ib leeg los ntawm ib pawg methylene (CH2). Rau piv txwv , methane, ethane, thiab propane yog ib feem ntawm a homologous series.
Khaws qhov no hauv kev xav, dab tsi yog txhais los ntawm homologous series?
Cov alkanes, alkenes thiab cycloalkanes yog cov piv txwv ntawm homologous series . A homologous series yog ib pawg ntawm cov tshuaj uas muaj cov tshuaj zoo sib xws thiab tuaj yeem sawv cev los ntawm cov qauv dav dav.
Kuj Paub, homologous series Class 10 yog dab tsi? CBSE NCERT Notes Chav Kawm 10 Chemistry Carbon thiab Nws Chemistry. A series ntawm cov carbon compounds uas tib pab pawg ua haujlwm hloov cov hydrogen atom hu ua a homologous series . Cov tebchaw no muaj cov tshuaj lom neeg zoo sib xws vim yog qhov sib ntxiv ntawm tib hom kev ua haujlwm thoob plaws hauv cov saw hlau.
Qhov sib thooj, homologous series luv teb yog dab tsi?
Teb . A homologous series yog a series ntawm cov tebchaw nrog tib cov qauv dav dav, feem ntau sib txawv los ntawm ib qho kev txwv xws li qhov ntev ntawm cov saw hlau carbon. Compounds nyob rau hauv ib homologous series feem ntau muaj cov txheej txheem ruaj khov uas ua rau lawv muaj cov tshuaj lom neeg thiab lub cev zoo sib xws.
Cov piv txwv ntawm homologous series yog dab tsi?
Piav nrog ib piv txwv . A homologous series yog a series ntawm cov khoom sib txuas uas muaj cov lej sib txawv ntawm cov pa roj carbon atoms tab sis muaj tib pab pawg ua haujlwm. Rau piv txwv , methane, ethane, propane, butane, thiab lwm yam yog tag nrho ib feem ntawm alkane homologous series.
Pom zoo:
Dab tsi yog qhov sib piv thiab piv txwv?
Inverse proportion. Inverse proportions tshwm sim thaum ib tus nqi nce thiab qhov txo qis. Piv txwv li, ntau tus neeg ua haujlwm ntawm txoj haujlwm yuav txo lub sijhawm los ua kom tiav cov haujlwm. Lawv yog inversely proportional
Dab tsi yog txhais los ntawm lub sij hawm dissociation thiab dab tsi yog ib qho piv txwv ntawm cov khoom uas dissociates?
Dissociation, nyob rau hauv chemistry, sib cais ntawm ib yam khoom mus rau hauv atoms los yog ions. Thermal dissociation tshwm sim ntawm qhov kub thiab txias. Piv txwv li, hydrogen molecules (H 2) dissociate rau hauv atoms (H) ntawm kub heev; ntawm 5,000 ° K txog 95% ntawm cov molecules hauv cov qauv ntawm hydrogen yog dissociated rau hauv atoms
Dab tsi yog qhov txawv ntawm instantaneous thiab nruab nrab ceev dab tsi yog qhov piv txwv loj tshaj ntawm kev ceev ceev?
Qhov nruab nrab ceev yog qhov ceev nruab nrab ntawm lub sijhawm. Instantaneous ceev yuav yog qhov ceev txhua qhov muab tam sim ntawd hauv lub sijhawm ntawd, ntsuas nrog lub ntsuas ntsuas lub sijhawm
Dab tsi yog qhov txawv ntawm microevolution thiab macroevolution Dab tsi yog qee qhov piv txwv ntawm txhua tus?
Microevolution vs. Macroevolution. Piv txwv ntawm cov kev hloov microevolutionary no yuav suav nrog kev hloov ntawm hom xim lossis loj. Macroevolution, piv txwv li, yog siv los hais txog kev hloov pauv ntawm cov kab mob uas tseem ceeb txaus uas, dhau sijhawm, cov kab mob tshiab yuav raug suav tias yog hom tshiab nkaus xwb
Cov txheej txheem dab tsi ua rau Bowen cov tshuaj tiv thaiv series piv txwv?
Nws yog ib qho txhais tau tias ntawm kev txheeb xyuas cov igneous silicate minerals los ntawm qhov kub ntawm lawv crystallise. Bowen's Reaction Series piav qhia txog qhov kub ntawm qhov sib txawv ntawm cov khoom siv silicate hloov pauv los ntawm cov kua mus rau theem khoom (los yog los ntawm cov khoom mus rau cov kua)
