You would have to use the ideal gas law: PV = nRT where,
P = pressure
V = volume
n = moles
R = universal gas constant for a specific pressure (in this case it's 62.364 torr)
T = temperature in Kelvin
First, convert Celsius to kelvin by adding 273 to 25, which gives you 298K
Now plug in your variables to find n:
(800 torr)(1.25 L) = n(62.364)(298K)
1000 = 18584.472n
Now divide 1000 by 18584.472 to get n:
1000/18584.472 = 0.054 moles
As the H bond of the butanol is more effective and strong than Van der Waals forces of the ether the surface tension in alcohol is more intensive.
So the correct answer is e)
Answer:
Acceleration due to gravity is reduced to half its value on the earth's surface at an altitude of 2.65×106 m
<u>Answer:</u> The
for the reaction is -297 kJ.
<u>Explanation:</u>
Hess’s law of constant heat summation states that the amount of heat absorbed or evolved in a given chemical equation remains the same whether the process occurs in one step or several steps.
According to this law, the chemical equation is treated as ordinary algebraic expressions and can be added or subtracted to yield the required equation. This means that the enthalpy change of the overall reaction is equal to the sum of the enthalpy changes of the intermediate reactions.
The given chemical reaction follows:

The intermediate balanced chemical reaction are:
(1)

(2)

The expression for enthalpy of the reaction follows:
![\Delta H^o_{rxn}=\frac{[1\times (-\Delta H_1)]+[1\times \Delta H_2]}{2}](https://tex.z-dn.net/?f=%5CDelta%20H%5Eo_%7Brxn%7D%3D%5Cfrac%7B%5B1%5Ctimes%20%28-%5CDelta%20H_1%29%5D%2B%5B1%5Ctimes%20%5CDelta%20H_2%5D%7D%7B2%7D)
Putting values in above equation, we get:

Hence, the
for the reaction is -297 kJ.
