How are the forces that cause earthquakes and volcanic eruptions similar? How are they different?

They both are caused by quakes in the bottom of the ocean or moves in tectonic plates, so they are caused by giant forces moving other giant land masses.

Earthquakes are when the tectonic plates hit each other and volcanic eruptions are when the plates push up against each other and release the magma below the estates crust

Determine the freezing point and boiling point of a solution that has 68.4 g of sucrose
Ymorist [56]

Answer:

Freezing T° of solution = - 3.72°C

Boiling T° of solution =  101.02°C

Explanation:

To solve this we apply colligative properties. Firstly, freezing point depression:

ΔT = Kf . m . i

ΔT = Freezing T° of pure solvent - Freezing T° of solution

Kf = Cryoscopic constant, for water is 1.86 °C/m

m = molality (moles of solute in 1kg of solvent)

i = Ions dissolved in solution

Our solute is sucrose, an organic compound so no ions are defined. i = 1.

Let's determine the moles: 68.4 g . 1mol/ 342g = 0.2 moles

molality = 0.2 mol / 0.1kg of water = 2 m

We replace data: ΔT = 1.86°C/m . 2m . 1

Freezing T° of solution = - 3.72°C

Now, we apply elevation of boiling point: ΔT = Kb . m . i

ΔT = Boiling T° of solution - Boiling T° of  pure solvent

Kf = Ebulloscopic constant, for water is 0.512 °C/m

We replace:

Boiling T° of solution - Boiling T° of pure solvent = 0.512 °C/m . 2 . 1

Boiling T° of solution = 0.512 °C/m . 2 . 1 + 100°C → 101.02°C

How long would it take to produce enough aluminum to make a case (24 cans) of aluminum soft drink cans if each can used 3 g of a
kozerog [31]

Answer : It takes time to produce 3 g of aluminium is, 165 seconds.

Explanation :

As we are given that the mass of aluminium is, 3 grams. Now we have to calculate the total mass of aluminum.

Total mass of aluminum = 3g × 24 = 72 g

Now we have to calculate the moles of aluminum.

\text{Moles of Al}=\frac{\text{Mass of Al}}{\text{Molar mass of Al}}

Molar mass of Al = 27 g/mol

\text{Moles of Al}=\frac{72g}{27g/mol}=2.67mol

As, 1 mole of Al has 3 Faradays

So, 2.67 mole of Al has = 2.67\times 3=80.1 Faradays

and,

Charge = 80.1\text{ Faradays}\times \frac{96500\text{ coulombs}}{1\text{ Faradays}}=7.73\times 10^6\text{ coulombs}

Current = 5.00\times 10^4A\times \frac{93.9}{100}=46950A

Now we have to calculate the time.

Time=\frac{Charge}{Current}=\frac{7.73\times 10^6}{46950}=164.6s\aaprox 165s

Hence, it takes time to produce 3 g of aluminium is, 165 seconds.
