Unformatted text preview: Chem 171 Quiz 10 Version A (CO 2 Enthalpy Key) 1. Calculate the density of SO 2 gas at 40 o C and 730 mmHg? PV = nRT and R = 0.08206 L atm mol-1 K-1 . S = 32.1. O = 16.0. PV = nRT PV = mRT/M P = mRT/VM = dRT/M d = PM/RT d = 0.961 atm x 64.1 g / mol / 0.08206 L atm K mol x 313 K d = 2.40 g / L 2. The following questions refer to the experiment entitled Enthalpy of Formation of Ammonium Salts. Indicate whether each statement is True or False. Enthalpy is an intensive property. The H for a reaction is independent of the state of the reactants and products. Enthalpy is a state function. H is the value of q measured under conditions of constant volume. The H of a reaction is the reciprocal of the enthalpy change of the reverse reaction. Enthalpy is an intensive property. False The H for a reaction is independent of the state of the reactants and products. False Enthalpy is a state function. True H is the value of q measured under conditions of constant volume. False The H of a reaction is the reciprocal of the H of the reverse reaction. False Chem 171 Quiz 10 Version B...
