Answer:
17.2 moles of Iron are required
Explanation:
Based on the chemical reaction:
2Fe + 3S → Fe₂S₃
<em>2 moles of Fe react with 3 moles of S to produce 1 mole of Iron (III) sulfide</em>
<em />
Assuming and excess of sulfur, if we want to obtain 8.6 moles of Fe₂S₃ are required:
8.6 moles Fe₂S₃ * (2 moles Fe / 1mol Fe₂S₃) =
<h3>17.2 moles of Iron are required</h3>
I suppose it false, since the oxidation involves the loss or removal of the electrons such forth it does not gain electrons.
Cl-35, as the atomic mass of Chlorine (35.45) is closer to the number 35 than to the number 37. A higher abundance of CL-35 isotope would have caused the atomic number (which is an average of the values of all isotopes of a substances taking relative abundance into consideration) to decrease from 36, which would appear to be the average.
