With a solution in them connected by a liquid salt bridge junction filled with KNO3. In one solution you have a graphite electrode that is connected with a wire to a copper electrode in the second soution. The soution in contact with the graphite electrode consists of dissolved Sn(NO3)2. The solution in contact with the copper electrode consists of dissolved CuNO3.
a) write the standard half cell reduction reaction equation for each solution?
b) what are the standard half cell potentials; E anode and E cathode?
c) If the electrochemical cell is allowed to operate as a gavanic cell, which solution species will be oxidized, which solution species will reduce?
d) write the sybolic representation for the galvanic cell.
e) what would "standard conditions" for this galvanic cell be?
f) If the cell is at standard conditions, determine the cell potential(E cell).
What is the rate of entropy generation within the tank? 3.) If we duplicated the stream conditions (temperatures, pressures, and flowrates) with an internally reversible process, what is the maximum rate at which work could be obtained?
how do you caclulate the theoretical yield? I began using 2.00 g of Salicylic acid, 5.0 mL of acetic anhydride, and added 5 gtts of concentrated sulfuric acid.
If the pressure exerted on a 100-L weather balloon changes from 1.0 atm to 2.0 atm, what would be the volume of the balloon at the higher pressure? Assume the temperature does not change and tha balloon has no leaks.
Zn(s) + 2 HCl(aq) H2(g) + ZnCl2(aq) When 25.0 g of Zn reacts, how many L of H2 gas are formed at 25 °C and a pressure of 854 mmHg?
Applying energy to dry ice causes the molecules to phase change straight from a solid to a gas, sublimation. When gas particles hit the walls of a container, they exert pressure. As we apply energy to dry ice, the gas molecules move faster which..
The reading on a mercury manometer at 25 deg C (open to the atmosphere at one end) is 56.38 cm. The local acceleration of gravity is 9.832 m s-2.
Find the reaction order using a Powell plot or the fractional-life method and also estimate the rate constant
Calculate the theoretical yield when 7.0 ml of acetic anhydride
why a bromine radical is more selective than a chlorine radical during abstraction of a hydrogen on a hydrocarbon?
How much water must be added to 534. mL of 0.180 M HCl to produce a 0.135 M solution? (Assume that the volumes are additive.)
Show how to make N-methylpropionamide using propionic acid and methylamine and other necessary reagents. The methylamine and propionic acid do not both have to be used in the first step.
A volume of 95.0 ml of H2O is initially at room temperature (22.0 C). A chilled steel rod at 2.00 C is placed in the water. If the final temperature of the system is 21.1 C .
