Answer:

The correct answer is option B.

Explanation:

Enthalpy of the system = \Delta H=+25 kJ=25,000 J

Entropy of the system =\Delta S=+5.0 J/K

Temperature of the system =T =23°C = 296 K

The Gibbs's free energy is given by;

\Delta G=\Delta H-T\Delta S

\Delta G=25,000 J-296 K\times 5.0 J/K =23,520 J=23.5 kJ

The value of ΔG is positive which means that system is not spontaneous.

Hence, from the given options the most closest value to our answer is option B.

Given the following equation: 8Fe+S8=8FeS
maxonik [38]

Answer:

a. 2954g of FeS

b. 1143g of FeS

Explanation:

Based on the reaction:

8 Fe + S₈ → 8 FeS

<em>8 moles of Fe reacts with 1 mole of S₈ to produce 8 moles of FeS</em>

<em />

a. 4.2mol sulfur produce:

4.2mol S₈ × ( 8 mol FeS / 1 mol S₈) = <em>33.6mol FeS</em>. As molar mass of FeS is 87.92g/mol, mass is:

33.6mol FeS × ( 87.92g / 1 mol FeS) = <em>2954g of FeS</em>

<em />

b. 13mol Fe produce:

13mol Fe × ( 8 mol FeS / 8 mol Fe) = <em>13mol FeS</em>. In mass:

13 mol FeS × ( 87.92g / 1 mol FeS) = <em>1143g of FeS</em>

Why is aluminium used to make outer covering of aeroplane?
iogann1982 [59]

Answer:

Aluminum is ideal for aircraft manufacture because it's lightweight and strong. Aluminum is roughly a third the weight of steel, allowing an aircraft to carry more weight and or become more fuel efficient. Furthermore, aluminum's high resistance to corrosion ensures the safety of the aircraft and its passengers.
