The structure of polyurethane formed by the copolymerization of a diol with a diisocyanate is to be drawn. Concept introduction: The polymers (repeating structural units) are derived from the simple and reactive molecules, called as monomers. Depending upon the mode of polymerization , polymerization mainly occurs by addition and condensation polymerization reactions. Copolymerization reactions are defined as the reactions of two different monomers forming a copolymer . Polyurethane is formed by the copolymerization of diol with diisocyanate. To determine: The structure of polyurethane formed by the copolymerization of a diol with a diisocyanate.

Question

A certain half-reaction has a standard reduction potential Ered +1.26 V. An engineer proposes using this half-reaction at the anode of a galvanic cell that must provide at least 1.10 V of electrical power. The cell will operate under standard conditions. Note for advanced students: assume the engineer requires this half-reaction to happen at the anode of the cell. Is there a minimum standard reduction potential that the half-reaction used at the cathode of this cell can have? If so, check the "yes" box and calculate the minimum. Round your answer to 2 decimal places. If there is no lower limit, check the "no" box.. Is there a maximum standard reduction potential that the half-reaction used at the cathode of this cell can have? If so, check the "yes" box and calculate the maximum. Round your answer to 2 decimal places. If there is no upper limit, check the "no" box. yes, there is a minimum. 1 red Πν no minimum Oyes, there is a maximum. 0 E red Dv By using the information in the ALEKS…
