Pyrophoric cov ntaub ntawv yog tshuaj uas tuaj yeem tshwm sim thaum raug huab cua … Pyrophoric hlau sulfide hlau sulfide Iron(II) sulfide lossis ferrous sulfide(Br. E. sulphide) yog ib qho ntawm tsev neeg cov tshuaj sib xyaw thiab cov zaub mov nrog cov qauv kwv yees FeS. https://en.wikipedia.org › wiki › Iron(II)_sulfide
Iron(II) sulfide - Wikipedia
yog tsim thaum hlau oxide (xeb) hloov mus ua hlau sulfide nyob rau hauv muaj hydrogen sulfide. Cov tshuaj tiv thaiv tshuaj no tsuas yog siv rau hauv cov pa oxygen tsawg xwb.
Cov khoom siv pyrophoric yog dab tsi?
cov ntaub ntawv Pyrophoric yog cov khoom uas ignite sai li sai tau thaum raug oxygen. Lawv kuj tuaj yeem ua dej-reactive, qhov twg cov cua sov thiab hydrogen (cov pa hluav taws xob) raug tsim.
Pyrophoric reagent yog dab tsi?
Pyrophoric reagents yog cov khoom uas ignite tam sim ntawd thaum raug oxygen, thiab feem ntau kuj yog dej-reactive, qhov twg tshav kub thiab hydrogen (flammable gas) raug tsim.
piv txwv ntawm cov tshuaj pyrophoric yog dab tsi?
Cov ntaub ntawv Pyrophoric yog cov khoom siv hluav taws xob tam sim ntawd thaum raug oxygen. … Piv txwv ntawm cov ntaub ntawv xws li hlau hydrides, cov hmoov hlau sib faib zoo, nonmetal hydride thiab alkyl compounds, phosphorus dawb, alloy ntawm cov khoom siv reactive thiab organometallic compounds, nrog rau alkyllithiums.
pyrophoric siv rau dab tsi?
tshuaj Pyrophoric yog siv hauv kev tshawb fawb los catalyze qee qhov kev cuam tshuam thiab feem ntau tau muab tso rau hauv cov khoom kawg. Txawm li cas los xij, lawv ua rau muaj kev phom sij rau lub cev. Lawv yog cov kua thiab cov khib nyiab uas yuav ignite ib txwm nyob rau hauv lub xub ntiag ntawm oxygen thiab dej.
