Kev npaj thiab tshuaj tiv thaiv
Cu2S tuaj yeem npaj tau los ntawm cua sov tooj liab muaj zog hauv sulfur vapor lossis H 2 S Cov tshuaj tiv thaiv ntawm tooj liab hmoov hauv molten sulfur sai ua Cu2S, whereas pellets ntawm tooj liab yuav tsum tau kub ntau dua. Cu2S reacts with oxygen to form SO2: 2 Cu2S + 3 O 2 → 2 Cu2O + 2 SO.
