Tin (II) oxide (stannous oxide) yog ib qho sib xyaw nrog cov qauv SnO. Nws yog tsim los ntawm tin thiab oxygen qhov twg tin muaj lub xeev oxidation ntawm +2. Muaj ob daim ntawv, daim ntawv xiav-dub ruaj khov thiab daim ntawv liab metastable.
Hauv qhov no, tin ua los ntawm dab tsi?
Tin (Sn), cov khoom siv tshuaj muaj nyob hauv tsev neeg carbon, Pawg 14 (IVa) ntawm lub sijhawm teem sijhawm. Nws yog mos, silvery dawb hlau nrog ib tug bluish tinge, paub rau ancients nyob rau hauv bronze, ib tug alloy nrog tooj liab. Tin yog dav siv rau plating steel cov kaus poom siv los ua cov ntim khoom noj, hauv cov hlau siv rau cov kabmob, thiab hauv cov khoom siv.
Ib yam li ntawd, xim dab tsi yog tin oxide? Specifications

Ntawm no, dab tsi yog cov tshuaj formula ntawm tin oxide?
SnO2
tin oxide zoo li cas?
Nqe lus piav qhia: Tin (iv) oxide tshwm raws li dawb los yog tawm-dawb crystalline khoom los yog hmoov. mp: 1127 ° C, Sublimes: 1800-1900 ° C, ntom: 6.95 g / cm3 Insoluble hauv dej. Tin dioxide yog a hlau oxide compound uas muaj tin (IV) covalently khi rau ob lub atoms oxygen.

Lub hauv paus chiv keeb ntawm lo lus 'Thermometer' Qhov thib ob ntawm lo lus, 'meter', los ntawm Fabkis -mètre (uas muaj nws cov hauv paus hauv lub post-classical Latin: -meter, -metrumand lub ancient Greek, -Μέτρο ν, lossis metron, uas txhais tau tias ntsuas qee yam, xws li qhov ntev, qhov hnyav, lossis dav)
Cov ntsiab lus dab tsi muaj nyob hauv orthoclase feldspar?
Cov feldspars tau muab faib ua 2 pawg dav: plagioclase, uas muaj calcium thiab sodium; thiab orthoclase, uas muaj cov poov tshuaj
Dab tsi yog lub ntsiab lus ntawm kev hloov pauv lom neeg hauv cov ntsiab lus ntawm allele zaus?
Microevolution, los yog evolution ntawm ib tug me me, yog txhais raws li ib tug kev hloov nyob rau hauv lub zaus ntawm noob variants, alleles, nyob rau hauv ib tug pej xeem ntau tiam. Lub teb ntawm biology uas kawm txog allele frequencies nyob rau hauv cov pejxeem thiab yuav ua li cas lawv hloov lub sij hawm yog hu ua pej xeem noob caj noob ces
Vim li cas cov ntsiab lus thiab cov ntsiab lus yog cov tshuaj ntshiab?
Elements thiab compounds yog ob qho tib si piv txwv ntawm cov khoom ntshiab. Ib yam khoom uas tuaj yeem tawg mus rau hauv cov tshuaj lom neeg yooj yim dua (vim tias nws muaj ntau dua ib qho) yog ib qho khoom sib xyaw. Piv txwv li, dej yog acompound tsim los ntawm cov ntsiab lus hydrogen thiaboxygen
Puas yog cov ntsiab lus uas muaj cov tshuaj lom neeg zoo sib xws yuav pom nyob rau tib lub sijhawm lossis hauv tib pab pawg piav qhia koj cov lus teb?
Qhov no yog vim hais tias cov tshuaj muaj zog nyob ntawm tsis muaj valence electrons. Raws li nyob rau hauv ib pawg tag nrho cov ntsiab lus muaj tib yam tsis muaj valence electron uas yog vim li cas lawv muaj cov tshuaj zoo sib xws tab sis nyob rau hauv ib lub sij hawm tsis muaj valence electron sib txawv uas yog vim li cas lawv txawv nyob rau hauv chemical zog
