Part III. Redox and Thermodynamics 1. Sketch galvanic cells based on the following overall reactions. Show the direction of electron flow, the direction of ion movement through the salt bridge, and identify the cathode and anode. Give the overall balanced reaction. Assume that all concentrations are 1.0 M and that all partial pressures are 1.0 atm. IO3- (aq) + Fe2+ (aq) ? Fe3+ (aq) + I2 (aq) 2. Write the standard line notation for the cell in Part III Question #1. 3. Calculate the E°cell values for the galvanic cell in Question #1. IO3- (aq) + Fe2+ (aq) ? Fe3+ (aq) + I2 (aq) 4. Calculate ?G° at 25 °C for the reaction in Part III Question #1. 5. Assume that the reaction is at equilibrium at 25 °C (under standard conditions. Calculate the equilibrium constant K.
How many unpaired electrons in the F22+ ion are based on molecular orbital theory? The order of the molecular orbitals are (σ2s)(σ*2s)(σ2p)(π2p)(π*2p)(σ*2p).
80.0 grams of diiodine pentoxide reacts with 28.0 grams of carbon monoxide. How many grams of I2 could be produced?
Which of these elements occupies a position on the periodic table that is not entirely consistent with its chemical properties
A flask of Argon gas is connected to the left arm of a manometer. The Hg level is 76.1cm. The right arm of the manometer is open to the atmosphere and has a Hg level of 63.9cm. The atmospheric pressure of the lab is 0.679 bar. What is the pressure..
Three gases (8.00 rm g of methane, CH_4, 18.0 g of ethane, C_2H_6, and an unknown amount of propane, C_3H_8) were added to the same 10.0 L container.
