An aquifer is D. an underground geological formation that contains a large amount of water.
Answer:
No, it is not feasible because the Gibbs free energy change is positive
Explanation:
∆Hreaction= (-602 KJ/mol) - (-348 KJ/mol) = -254 KJ/mol
∆Sreaction = (42 + 27) J/Kmol - (33 + 44) J/K = -8J/Kmol
From;
∆G = ∆H - T∆S
∆G = 254 × 10^3 J/mol - [340K × (-8 J/Kmol)]
∆G = 2.57 × 10^5 J/mol
Note that when the change in free energy is positive, a reaction is non spontaneous. Only a reaction that has a negative change in free energy is spontaneous.
Answer:
353 grams per mole
Explanation:
Candle wax is defined by the chemical formula C25H52 and has a molar mass of 353 grams per mole.
When it switches to a lower orbital, the atom emits energy in the form of photons.
