Answer:
1.12 moles
Explanation:
To find the amount of moles, you need to use the Ideal Gas Law:
PV = nRT
In this equation,
-----> P = pressure (atm)
-----> V = volume (L)
-----> n = moles
-----> R = Ideal Gas constant (0.08206 atm*L/mol*K)
-----> T = temperature (K)
After converting the temperature from Celsius to Kelvin, you can plug the given values into the equation and solve for "n".
P = 1.00 atm R = 0.08206 atm*L/mol*K
V = 25.0 L T = 0. °C + 273 = 273 K
n = ? moles
PV = nRT
(1.00 atm)(25.0 L) = n(0.08206 atm*L/mol*K)(273 K)
25.0 = n(22.4)
1.12 = n
Answer:
1-<u>Pentanol </u>has the highest boiling point.
Explanation:
Boiling points of given compounds are as follow,
1) 2-Pentanone = 101 °C
2) 1-Pentanol = 138 °C
3) Pentane = 36.1 °C
4) Pentanal = 103 °C
Pentanol has greatest boiling point as compare to others because it involes a strongest intermolecular interactions called as hydrogen bond interactions. Remaining compounds lack the direct attachement of hydrogen to most electrnegative atom like oxygen which is present in 1-Pentanol.
Answer:
electron shells
Explanation:
Eletrons are on the outeermost part of the atom called electron shells.
If the enthalpy is positive and the entropy is positive, the Gibbs energy will always be positive, and the reaction will never be feasible.
<h3>What is the Gibbs Free Energy?</h3>
The Gibb Free Energy is used to obtain the feasibility of a reaction. If the Gibbs free energy is positive the reaction is not spontaneous. If the value is negative, the reaction is spontaneous while a zero values indicates equilibrium.
From the equation;
ΔG = ΔH - TΔS, it follows that if the enthalpy is positive and the entropy is positive, the Gibbs energy will always be positive, and the reaction will never be feasible.
