Answer:- The pressure of ethanol would be 109 mmHg.
Solution:- This problem is based on Clausius clapeyron equation--
Given, = 63.5 + 273 = 336.5 K
= 34.9 + 273 = 307.9 K
= 400 mmHg
= ?
= 39.3 kJ/mol = 39300 J/mol
R = 8.314 J/mol.K
Let's plug in the values in the equation and do the calculations.
= 1.30
On taking anti ln to both sides...
=
= 3.67
= 400/3.67
= 109 mmHg
There are several process in the nature, which keeps water cycling between them. By Precipitation, Earth's sphere gets water which we use in several ways, and by evaporation & sublimation, it goes back to upper spheres of the Earth's atmosphere and cycle happens again & again.
Hope this helps!
Answer:
(a) Alkali metals: Francium (Fr)
(b) Chalcogens: Polonium (Po)
(c) Noble gases: Radon (Rn)
(d) Alkaline earth metals: Radium (Ra)
Explanation:
In the periodic table, the atomic mass increases down the group. Therefore, the last element of a group is the heaviest element of the group.
(a) alkali metals: The chemical elements that are present in group 1 of the periodic table, except hydrogen.
<u>The heaviest member of this group is francium (Fr)</u>
(b) chalcogens: The chemical elements that are present in group 16 of the periodic table
<u>The heaviest member of this group is polonium (Po)</u>
(c) noble gases: The chemical elements that are present in group 18 of the periodic table
<u>The heaviest member of this group is radon (Rn)</u>
(d) alkaline earth metals: The chemical elements that are present in group 2 of the periodic table.
<u>The heaviest member of this group is radium (Ra)</u>

Explanation:
I took the quiz also just think that doesn't seem like a good, higher level scientist, or popular one, SO THERE YOU GUYS GO!!!
Answer:
The equilibrium constant Kp = 29.68
Explanation:
2SO3(g) ⇄ 2SO2(g) + O2(g)
Kp = (pSO2)²(pO2)/(pSO3)²
We can use ideal gas formula to find pressure of each: PV = nRT thus P=nRT/V,
with n=moles at equilibrium; R=0.082057L.atm.mol⁻¹.K⁻¹ (gas constant); T=1.30*10^3K; V=13.2L
After substituting each values:
P(SO3) = 0.873 atm
P(SO2) = 3.15 atm
P(O2) = 2.28 atm
Kp = (3.15²×2.28)/(0.873)² = 29.68
