Question: A gaseous hydrocarbon reacts completely with oxygen gas to form
A gaseous hydrocarbon reacts completely with oxygen gas to form carbon dioxide and water vapor. Given the following data, determine ΔHof for the hydrocarbon: ΔHrxn = –2044.5 kJ/ mol ΔHof (CO2) = –393.5 kJ/ mol ΔHof (H2O) = –242 kJ/ mol Density of CO2 and H2O mixture at 1 atm, 200oC = 0.751 g/ L The Density of the hydrocarbon is less than the Density of Kr at the same conditions.
Answer to relevant QuestionsChoose the substance with the larger positional probability in each case. a. 1 mole of H2 (at STP) or 1 mole of H2 (at 100oC, 0.5 atm) b. 1 mole of N2 (at STP) or 1 mole of N2 (at 100 K, 2.0 atm) c. 1 mole of H2O(s) (at 0oC) ...Consider a rigid, insulated box containing 0.400 mole of He(g) at 20.0oC and 1.00 atm in one compartment and 0.600 mole of N2(g) at 100.0oC and 2.00 atm in the other compartment. These compartments are connected by a ...A sample of ice weighing 18.02 g, initially at 230.0oC, is heated to 140.0oC at a constant pressure of 1.00 atm. Calculate q, w, ΔE, ΔH, and ΔS for this process. The molar heat capacities (Cp) for solid, liquid, and ...For each of the following pairs of substances, which sub-stance has the greater value of S8 at 25oC and 1 atm? a. Cgraphite(s) or Cdiamond(s) b. C2H5OH(l) or C2H5OH(g) c. CO2(s) or CO2(g) d. N2O(g) or He(g) e. HF(g) or ...For ammonia (NH3) the enthalpy of fusion is 5.65 kJ/ mol, and the entropy of fusion is 28.9 J K-1 mol-1. a. Will NH3(s) spontaneously melt at 200. K? b. What is the approximate melting point of ammonia?
