Answer: 26.5 mm Hg
Explanation:
The vapor pressure is determined by Clausius Clapeyron equation:
where,
= initial pressure at 
= ?
= final pressure at 
= 100 mm Hg
= enthalpy of vaporisation = 28.0 kJ/mol =28000 J/mol
R = gas constant = 8.314 J/mole.K
= initial temperature = 
= final temperature =
Now put all the given values in this formula, we get
![\log (\frac{P_1}{100})=\frac{28000}{2.303\times 8.314J/mole.K}[\frac{1}{299.5}-\frac{1}{267.9}]](https://tex.z-dn.net/?f=%5Clog%20%28%5Cfrac%7BP_1%7D%7B100%7D%29%3D%5Cfrac%7B28000%7D%7B2.303%5Ctimes%208.314J%2Fmole.K%7D%5B%5Cfrac%7B1%7D%7B299.5%7D-%5Cfrac%7B1%7D%7B267.9%7D%5D)
Thus the vapor pressure of 
in mmHg at 26.5 ∘C is 26.5

Answer:
1.13 × 10⁶ g
Explanation:
Let's consider the reduction of aluminum (III) from Al₂O₃ to pure aluminum.
Al³⁺ + 3 e⁻ → Al
We can establish the following relations:
- 1 Ampere = 1 Coulomb / second
- The charge of 1 mole of electrons is 96,468 c (Faraday's constant)
- 1 mole of Al is produced when 3 moles of electrons circulate
- The molar mass of Al is 26.98 g/mol.
The mass of aluminum produced under these conditions is:
C. Weathering, plate movements and volcanoes destroyed many of
the craters
Explanation:
The earth is a dynamic planet. Both external and internal processes sculpt and shapes the surface and interior of the earth primarily from the energy from the sun and the primordial heat accumulated during the formation of the earth.
- The period of heavy bombardment of the earth resulted in the creation of craters and other impact features on the earth surface.
- As earth evolved, the process of weathering which is one of the tools of denudation caused the lowering and changing of the earth. Through this process sedimentary rocks were formed.
- The movement of the earth through plate tectonics also greatly shaped the earth. New materials from the interior were brought to the surface. Some existing parts were destroyed at subduction zones. Some also became elevated.
- Volcanism also brought new materials to the surface and this changed the terrain.
