Answer:
C. -76 mV
Explanation:
The potential of a cell can be calculated by the Nernst equation:
E = E° - (RT/nF)*lnQ
Where E° is the standard potential, R is the gas constant, T is the temperature, F is the Faraday constant, n is the number of electrons at the redox reaction, and Q is the reaction coefficient (products/reactants).
For T = 298 K, the equation can be modified for:
E = E° - (0.0592/n)*logQ
And
E° = -ΔG°/nF
Where ΔG° is free energy, so E° = 0V.
Because the voltage will be calculated of the interior relative to the exterior, the interior is the reactant, and the exterior is the product. So, Q = [Na⁺]exterior/[Na⁺]interior. 1 electron has been replaced in this reaction, so n = 1.
E = -0.0592*log(20/1)
E = -0.076 V
E = -76 mV
Answer:
The adhesive is made up of two different layers.
The lower layer is made up of vertically aligned nanotubes.
The upper layer is made up of curly, spaghetti-like, nanotubes.
Because they are coming from the ground and always safe
