Oxyanions . Qee lub ntsiab lus tuaj yeem tsim ntau dua ib qho oxyanion ua (polyatomic ions uas muaj cov pa oxygen), txhua tus muaj cov lej sib txawv ntawm cov pa oxygen. Lub anion nrog ib qho ntxiv oxygen atom tshaj li (hauv paus) noj anion yog npe los ntawm kev muab per- thaum pib ntawm lub hauv paus thiab - noj thaum kawg.
Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog oxyanion muab ob qho piv txwv?
Piv txwv Oxyanion Nitrate (NO3-), Nitrite (NO 2 -), sulfite (SO3 2 -thiab hypochlorite (ClO-) yog tag nrho oxyanions.
Kuj Paub, qhov twg ion yog oxyanion hlwb? Ib oxyanion ua yog ib qho anion uas muaj oxygen. Nws yuav tsum muaj O thiab muaj cov nqi tsis zoo ntawm cov anion.
Ua li no, koj yuav nrhiav tau tus nqi ntawm Oxyanion li cas?
xam los ntawm Oxidation Number Tus oxidation tooj ntawm oxygen yog -2, thiab tus naj npawb oxidation ntawm hydrogen yog +1. Ntxiv ua ke cov lej oxidation ntawm tag nrho cov atoms hauv polyatomic ion. Hauv qhov piv txwv, -2 +1 = -1. Qhov no yog qhov nqi ntawm polyatomic ion.
Koj npe li cas acids?
Hauv binary yooj yim kua qaub , ib qho ion txuas nrog hydrogen. Cov npe rau tej ntawd kua qaub muaj cov lus ua ntej "hydro-", thawj lub suab ntawm anion, thiab cov lus "-ic". nyuaj kua qaub cov tebchaw muaj oxygen hauv lawv. Rau ib kua qaub nrog polyatomic ion, cov lus "-ate" los ntawm ion yog hloov nrog "-ic."

Lub pulsar yog dab tsi thiab dab tsi ua rau nws mem tes?
Pulsars yog rotating neutron hnub qub pom tias muaj pulses ntawm hluav taws xob ntawm lub sijhawm tsis tu ncua uas feem ntau yog li ntawm milliseconds mus rau vib nas this. Pulsars muaj cov hlau nplaum muaj zog heev uas funnels dav hlau ntawm cov khoom tawm raws li ob tus ncej sib nqus. Cov khoom nrawm no tsim cov kab teeb muaj zog heev
