Chapter 25, Problem 25.9QAP
Interpretation Introduction
Interpretation:
The method of calculating the half-wave potential of a species reacting at an electrode using equation 25-13 is to be stated.
Concept introduction:
The half-wave potential of a species reacting at an electrode is the potential. The current of the polarographic is equal to the half of the diffusion current at the half-wave potential. It is unique for the each element.

Speaking of composite materials, indicate the correct option:(A). Composite materials can only be: metal-polymer or polymer-polymer.(B). Composite materials can be made up of particles, but not fibers or sheets.(C). When the reinforcing particles are uniformly distributed in a composite material, there may be a greater tendency for it to have isotropic properties.(D). None of the above is correct.
If we are talking about viscoelastic modulus or viscoelastic relaxation modulus in polymers, indicate the correct option.(A). It reports the variation of elastic behavior as a function of time.(B). It is only useful for defining its glass transition temperature.(C). It only allows us to define the polymer degradation temperature.(D). Neither option is correct.
