Answer:

Theoretical yield = 31.8 g

Explanation:

The formula for the calculation of moles is shown below:

moles = \frac{Mass\ taken}{Molar\ mass}

For Al_2O_3

Mass of Al_2O_3  = 60.0 g

Molar mass of Al_2O_3  = 101.96128 g/mol

The formula for the calculation of moles is shown below:

moles = \frac{Mass\ taken}{Molar\ mass}

Thus,

Moles= \frac{60.0\ g}{101.96128\ g/mol}

Moles_{Al_2O_3}= 0.5885\ mol

Given: For C

Given mass = 30.0 g

Molar mass of C  = 12.0107 g/mol

The formula for the calculation of moles is shown below:

moles = \frac{Mass\ taken}{Molar\ mass}

Thus,

Moles= \frac{30.0\ g}{12.0107\ g/mol}

Moles_{C}= 2.4978\ mol

According to the given reaction:

Al_2O_3+3C\rightarrow 2Al+3CO

1 mole of aluminium oxide react with 3 moles of carbon

0.5885 mole of aluminium oxide react with 3\times 0.5885 moles of carbon

Moles of carbon = 1.7655 moles

Available moles of carbon = 2.4978 moles

Limiting reagent is the one which is present in small amount. Thus, aluminium oxide is limiting reagent.

The formation of the product is governed by the limiting reagent. So,

1 mole of aluminium oxide on reaction forms 2 moles of aluminium.

0.5885 mole of aluminium oxide on reaction forms 2\times 0.5885 moles of aluminium.

Moles of aluminium = 1.177 moles

Molar mass of aluminium = 26.981539 g/mol

Mass of sodium sulfate = Moles × Molar mass = 1.177 × 26.981539 g = 31.8 g

<u> Theoretical yield = 31.8 g</u>

Which term describes a section of Earht's structure below moving continents as parts of large plates?
Snezhnost [94]

"Asthenosphere" describes a section of Earth's structure below moving continents as parts of large plates.

Answer: Option C

<u>Explanation: </u>

The asthenosphere denoted as the upper mantle of a very sticky, mechanically weak and flexible area in the earth. It is located below the surface of the lithosphere at depths of about 80 and 200 km (in terms of miles, 50 and 120). The boundary is commonly called the lithospheric LAB - asthenosphere.

The asthenosphere is nearly solid, though some of its regions could be molten below mid-ocean ridges for an instance. The lower asthenosphere boundary isn't well defined. The asthenosphere's thickness depends primarily on the temperature.
