Question
Chapter 15, Problem 15.108EP
(a)
Interpretation Introduction
Interpretation: To determine the two reactants in the first step of the sulfate assimilation process.
Concept introduction: Sulfate assimilation is the process used for the production of hydrogen sulfide. The starting material for sulfate assimilation is sulfate ion. It is an oxidation-reduction process as the sulfur in sulfate ion is in oxidized form and in hydrogen sulfide it is present in the reduced form.
(b)
Interpretation Introduction
Interpretation: To determine the nonsulfur-containing reactant in the second step of the sulfate assimilation process.
Concept introduction: Sulfate assimilation is the process used for the production of hydrogen sulfide. The starting material for sulfate assimilation is sulfate ion. It is an oxidation-reduction process as the sulfur in sulfate ion is in oxidized form and in hydrogen sulfide it is present in the reduced form.
(c)
Interpretation Introduction
Interpretation: To determine the sulfur-containing product in the third step of the sulfate assimilation process.
Concept introduction: Sulfate assimilation is the process used for the production of hydrogen sulfide. The starting material for sulfate assimilation is sulfate ion. It is an oxidation-reduction process as the sulfur in sulfate ion is in oxidized form and in hydrogen sulfide it is present in the reduced form.
(d)
Interpretation Introduction
Interpretation: To determine the reactants in the fourth step of the sulfate assimilation process.
Concept introduction: Sulfate assimilation is the process used for the production of hydrogen sulfide. The starting material for sulfate assimilation is sulfate ion. It is an oxidation-reduction process as the sulfur in sulfate ion is in oxidized form and in hydrogen sulfide it is present in the reduced form.
