Enter your answer in the provided box. Roasting galena [lead(II) sulfide) is an early step in the industrial isolation of lead. How many liters of sulfur dioxide, measured at STP, are produced by the reaction of 5.75 kg of galena with 193 L of oxygen gas at 220°C and 2.00 atm? Lead(II) oxide also forms. LSO2
26. Roasting galena [lead(II) sulfide] is an early step in the industrial isolation of lead. How many liters of sulfur dioxide, measured at STP, are produced by the reaction of 7.30 kg of galena with 106 L of oxygen gas at 220°C and 2.00 atm? Lead(II) oxide also forms. L SO2
An environmental engineer is sampling the stack gas produced by a coal-burning power plant. The stack gas (a mixture of carbon dioxide, sulfur dioxide, and water) is pumped into a 20.0 liter cylinder at a pressure of 1.20 atm, and a temperature of 325 K. It is determined that the sample contains 0.315 mol of C02 and 0.494 mol of H20 a) How many moles of sulfur dioxide were present in the sample? b) What is the partial pressure (in...
