Fe2O3(s) + 3H2(g) → 2Fe(s) + 3H2O(1)<br> How many moles of iron can be made from 3 moles of Fe2O3?
enot [183]

<em>ANSWER - 6 MOLES OF </em><em>IRON</em>

Fe2O3(s) + 3H2(g) → 2Fe(s) + 3H2O(1)

One moles of Fe2O3 forming 2 moles of Fe

3 moles of Fe2O3 will form 2×3 = 6 moles of iron

Calculate the standard cell potential (E∘) for the reaction X(s)+Y+(aq)→X+(aq)+Y(s) if K = 5.59×10−3.
Blizzard [7]

Answer:

E° = -0.133 V

Explanation:

In the reaction:

X(s) + Y⁺(aq) → X⁺(aq) + Y(s)

<em>1 electron is transferred from X to Y</em>

Now, using Nernst equation:

E° = RT / nF ln K

<em>Where R is gas constant (8.314 J/molK), T is absolute temperature (Usually 298.15K), n are transferred electrons (1, for the reaction), F is faraday constant (96485C/mol) and K is equilibrium constant (5.59x10⁻³)</em>

Replacing:

E° = 8.314 J/molK*298.15K / 96485C/mol*1 ln 5.59x10⁻³

<em>E° = -0.133 V</em>
