We calculate by using the equation as follows:

Free Energy = DeltaG 

<span>The formula is DeltaG = Enthalpy - (Temperature)*(Entropy) </span>

<span>DeltaG = 1.25 * 10^5 J - (290)(300) </span>

<span>DeltaG or Free Energy = 38000 J/mol or 38kJ/mol. </span>

<span>This means that this system is not spontaneous at 290 K
</span>
Hope this answers the question. Have a nice day.

A train travels 98 kilometers in 4 hours, and then 61 kilometers in 3 hours. What is its average speed?
IrinaK [193]
Speed (velocity)=distance/time

V1=98km/4hr=24.5km/hr
V2=61km/3hr=20.3km/hr

Average speed (velocity)=total velocity/ number

Average speed (velocity)=44.8km/hr/2=22.4

So the average speed is 22.4km/hr

Which of these chemical equations demonstrates the law of conservation of mass as it applies to the combustion of ethane? A. 2 C
WINSTONCH [101]

A. 2 C₂ H₆ + 7 O₂ → 4 C O₂ + 6 H₂ O


according to law of conservation of mass , the total mass of reactants side must be same as the total mass of product side. so we need to check if each atom in the equation has same number on both side of the equation or not.

in this equation , we have

4 atoms of carbon left and 4 atoms of carbon on right

12 atoms of hydrogen on left and 12 atoms of hydrogen on right

14 atoms of oxygen on left and 14 atoms of oxygen on right
