What volume of hydrogen at STP required to reduce 7.95 grams of cupric oxide to give metal? |
|
Answer» SOLUTION :CUPRIC oxide is reduced to copper on treating with hydrogen `CuO+H_(2)to Cu+H_(2)O` 1 mole of CuO =1 mole of `H_(2)` 79.5 grams of CuO=22.4 L of `H_(2)` at STP 7.95 grams of CuO=? VOLUME of hydrogen required at STP `=(7.95)/(79.5) XX 22.4=2.24L` |
