From the information in the question, the E° and E for the cell is 0.00 V and 0.12 V.
Using the Nernst equation;
Ecell = E°cell - 0.0592/n log Q
We know that E°cell = 0.00 V since the anode and cathode are both made up of cadmium.
Substituting the given values into the Nernst equation;
Ecell = 0.00 V - 0.0592/2 log (1.0 × 10-5 M/0.100 M)
Ecell = 0.00 V - 0.0296 log(1 × 10^-4)
Ecell = 0.12 V

Answer:
Its the bottom one :) ......
Answer: The molar volume of any gas at standard pressure and standard temperature is 22.4 liters per mole.
Explanation:The ideal gas law is PV=nRT
P is pressure and if we consider standard pressure, then we have 1.00 atm.
V is volume and that is what we are trying to solve.
n is the number of moles, which is 1.00 moles since we are trying to determine the volume of a gas in one mole.
R is the ideal gas constant which equals
0.0821 (Liters x atmospheres)/(mole x kelvin)
T is the standard temperature which is 273 kelvin.
Rearrange the equation to solve for volume.
V = nRT/P
V = (1.00 mol)(0.0821 L atm/mol K)(273 K)/ 1.00 atm
V = 22.4 L
Answer:
6.32 × 10⁻³
3.2560008× 10⁷
5.630× 10⁰
9.5002× 10¹
Explanation:
Scientific notation is the way to express the large value in short form.
The number in scientific notation have two parts.
The digits (decimal point will place after first digit)
× 10 ( the power which put the decimal point where it should be)
For example:
0.00632
In scientific notation = 6.32 × 10⁻³
32,560,008
In scientific notation = 3.2560008× 10⁷
5.630
In scientific notation = 5.630× 10⁰
95.002
In scientific notation = 9.5002× 10¹
