(a)
Interpretation:
Interpret the given reaction is
Concept Introduction:
For a
If the oxidation state of the ion gets reduced to lower state, thus it is the reduction reaction.
The electrode on which half reaction in which addition of electron are taking place or ion accepting the electrons and getting reduced to lower state is known to be cathode.
The electrode on which half reaction in which release of electron are taking place or ion releases the electrons and getting oxidized to higher state is known to be anode.
(b)
Interpretation:
Number of mol of Fe2 O3 needed to produce 38.4 mol Fe to be determined.
Concept Introduction:
Number of mol of a compound can be determined by dividing the mass of compound in g by its molar mass as follows:
where, n is mol.
m is mass in g.
M is molar mass.
(c)
Interpretation:
Mass of CO needed to produce 38.4 mol Fe should be determined.
Concept Introduction:
Number of mol of a compound can be determined by dividing the mass of compound in g by its molar mass as follows:
where, n is mol.
m is mass in g.
M is molar mass.

- please help fill in the tablearrow_forwardAnswer F pleasearrow_forward4. Refer to the data below to answer the following questions: The octapeptide saralasin is a specific antagonist of angiotensin II. A derivative of saralasin is used therapeutically as an antihypertensive. Amino acid analysis of saralasin show the presence of the following amino acids: Ala, Arg, His, Pro, Sar, Tyr, Val, Val A.Sar is the abbreviation for sarcosine, N-methyl aminoethanoic acid. Draw the structure of sarcosine. B. N-Terminal analysis by the Edman method shows saralasin contains sarcosine at the N-terminus. Partial hydrolysis of saralasin with dilute hydrochloric acid yields the following fragments: Tyr-Val-His Sar-Arg-Val His-Pro-Ala Val-Tyr-Val Arg-Val-Tyr What is the structure of saralasin?arrow_forward
