Consider the thermochemical equation below. 4Na(s) + O2(g) → 2 Na2O(s) AH = -828 kJ/mol A. Which reactant is the limiting reactant if 30.0 g of sodium is reacted with 12.0 L of oxygen gas at 1525 torr and 285 K? You must explain how you determined the limiting reactant for full credit (10 points) Answer: Na is the limiting reactant (Explanation omitted) Study guide: Identify the limiting reactant. Use the ideal gas equation to determine the pressure, volume, moles, or temperature of a gas given all other values. PV = nRT Use the ideal gas equation in stoichiometric calculations. B. How much heat is evolved, in kJ, when 30.0 g of sodium is reacted with 12.0 L of oxygen gas at 1525 torr and 285 K? (6 points) Study guide: Calculate the enthalpy change of reaction and understand how it depends upon stoichiometric amounts of reactants and products. -270. k) or 270 k) of heat is evolved
