A metal "X" is used as a “sacrificial” anode on hulls of salt water vessels made of iron. The effect is to reverse the oxidation of iron to iron (II) by causing X to oxidize to the X ion. Calculate the voltage (in V, to two decimal places) for this reaction if it takes place under standard conditions. The standard reduction potential for X is -1.09 V (minus 1.09 V).
A current of 3.68 A is passed through a Sn(NO3)2 solution. How long, in hours, would this current have to be applied to plate out 5.40 g of tin?
How many seconds are required to produce 7.00 g of Osmium metal from theelectrolysis of molten OsCl2 with an electrical current of 16.0 A?
2. Tell whether each of these statements are true and false. If false, rewite it to make it a correct statement. Oxidation always occurs at the anode of an electrochemical cell. The anode of a voltaic cell is the ite of reduction and is negative. Standard conditions for electrochemical cells are a concentration of 1.0 M for disolved species and a pressure of 1 bar for gases. The potential of a voltaic cell does not change with temperature. All product-favored oxidation-reduction reactions have a standard cell voltage E°cell, with a negative sign.
In an electrochemical cell, a metal anode lost 0.286 g while a total volume of 0.04854 L of hydrogen gas was produced. The temperature was 298 K and the barometric pressure was 763.5 mm Hg. At 298 K, the vapor pressure of water is 23.8 mm Hg. What is the molar mass of the metal?
19. (a) Write a balanced equation for the reaction that occurs in a car battery when the ignition key is turned on. (b) Suppose that constant current of 450 A flowing through the engine for at least 10.0 seconds is needed to start a pick-up truck. How many grams of lead are consumed during this time? (c) If the battery operates at 12 V of potential, how much energy (in kJ) is produced?
In one application, a 0.010-mm layer of chromium must be deposited on a part with a total surface area of 3.3 m2 from a solution of containing chromium(III) ions. How long would it take to deposit the layer of chromium if the current was 33.46 A? The density of chromium (metal) is 7.19 g/cm3.
Please answer the attached question:
How many seconds does it takes to produce 5,0 L of aluminum sulfide, Cr2S3 measured at 0.95 atm and 23 °C by electrolysis of molten chromic sulfide, using a current of 1.5 A.
A metal "X" is used as a “sacrificial” anode on hulls of salt water vessels made of iron. The effect is to reverse the oxidation of iron to iron (II) by causing X to oxidize to the X ion. Calculate the voltage (in V, to two decimal places) for this reaction if it takes place under standard conditions. The standard reduction potential for X is -0.90 V (minus 0.90 V).
