Yam ntxwv : Tin yog ib tug silvery-dawb, mos, malleable hlau uas yuav ua tau heev polished. Tin muaj cov qauv crystalline heev thiab thaum a tin bar yog khoov, ib ' tin quaj' tau hnov, vim qhov tawg ntawm cov pob zeb no.
Ib yam li ntawd, tib neeg nug, lub cev lub cev ntawm tin yog dab tsi?
Tin yog ib tug mos mos, malleable, ductile thiab crystalline silvery-dawb hlau. Thaum ib lub bar tin yog bent, ib lub suab crackling hu ua " tin quaj" tuaj yeem hnov los ntawm qhov ntxaib ntawm cov muaju. Tin melts ntawm qis kub ntawm txog 232 ° C (450 ° F), qhov qis tshaj hauv pab pawg 14.
Ib yam li ntawd, dab tsi yog cov cuab yeej ntawm tin tau? Tin yog mos, pliable, nyiaj - dawb hlau. Tin tsis yooj yim oxidized thiab tiv thaiv corrosion vim tias nws muaj kev tiv thaiv los ntawm oxide zaj duab xis. Tin resists corrosion los ntawm distilled hiav txwv thiab cov kais dej mos, thiab tuaj yeem tawm tsam los ntawm cov kua qaub, alkalis thiab acid ntsev.
Tom qab ntawd, lo lus nug yog, dab tsi yog 3 lub cev lub cev ntawm tin?
- Xim: Silver-White.
- Malleability: Muaj peev xwm ua tau zoo li tus lossis khoov rau hauv cov ntawv nyias nyias (tin foil).
- Luster: muaj ci los yog ci.
- Ductility: Yooj yim rub los yog ncab rau hauv ib txoj hlua nyias.
- Conductivity: Kev sib kis tau zoo ntawm tshav kub lossis hluav taws xob.
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.
