SOLVED:A lead ore, galena, consisting mainly of lead(II) sulfide, is the principal source of lead. To obtain the lead, the ore is first heated in the air to form lead oxide. PbS(s) (3)/(2) O2(g) ⟶PbO(s) SO2(g) ΔH=-415.4 kJ The oxide is then reduced to metal with carbon. PbO(s) C(s) ⟶Pb(s) CO(g) ΔH= 108.5 k] Calculate ΔH for the reaction of one mole of lead(II) sulfide with oxygen and carbon, forming lead, sulfur dioxide, and carbon monoxide.

The volume of an irregularly shaped solid can be determined from the volume of water it displaces. A graduated cylinder contains 19.9 mL of water. When a small piece of galena, an ore of lead, is added, it sinks and the volume increases to 24.5 mL. What is the volume of the piece of galena in cm³ and in L?

When galena, an ore of lead that contains only Pb and S, is heated in oxygen, the ore decomposes to produce pure lead. In one such process, 7.85 g of galena gave 6.80 g of lead. Find the empirical formula of galena. | Numerade
