<span>∆T = i * Kf * m
Kf(cryoscopic constant of water) = -1.858°C·kg/mol
i = 1 (for glycerin)
m = molality of solute(glycerin) = nos of moles of glycerin / mass of solvent(water)[n/M]
n = 30.7g/92.09g = 0.33337moles
M is deduced from the density of water which is 1Kg/1000ml(1Kg/L)
M = 376ml * (1Kg/1000ml) = 0.376Kg
m is thus; 0.33337moles/0.376Kg = 0.8866mol/Kg
=> ∆T = 0.8866mol/Kg * 1 * -1.858°C·kg/mol
∆T = -1.647°C
~ -1.65°C.</span>
Answer:
subduction zone
Explanation:
it’s the subduction zone. I still remember some things from a few years ago when I had to learn about this.
Answer:Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away. No rock on Earth is hard enough to resist the forces of weathering and erosion.
Explanation:
1. Djibouti
2. Eritrea
3. Ethiopia
5. Somalia
Explanation:
The Horn of Africa is part of the African continent that has the shape of a horn, thus the name of it. It is located in the northern part of Eastern Africa. The area is mostly dominated by a high plateau, while the coastal parts have coastal plains. The four countries that occupy territory on the Horn of Africa are:
- Djibouti
- Eritrea
- Ethiopia
- Somalia
Ethiopia is the largest country in this part of Africa, and it occupies the central and western parts of it. Somalia is the second largest country here, and it occupies the majority of the eastern coast. Eritrea an Djibouti are the two smaller countries on the Horn of Africa, occupying its north and northeastern part.
Basalt would make up Oceanic rock while Granite makes up Continental rock.
