Explain how earth plates and lithosphere are related

Chemistry
1 answer:
AnnyKZ [126]3 years ago
6 0

Crust, the upper layer of the Earth, is not always the same. Crust under the oceans is only about 5 km thick while continental crust can be up to 65 km thick. Also, ocean crust is made of denser minerals than continental crust.

The tectonic plates are made up of Earth’s crust and the upper part of the mantle layer underneath. Together the crust and upper mantle are called the lithosphere and they extend about 80 km deep. The lithosphere is broken into giant plates that fit around the globe like puzzle pieces. These puzzle pieces move a little bit each year as they slide on top of a somewhat fluid part of the mantle called the asthenosphere. All this moving rock can cause earthquakes.

The asthenosphere is ductile and can be pushed and deformed like silly putty in response to the warmth of the Earth. These rocks actually flow, moving in response to the stresses placed upon them by the churning motions of the deep interior of the Earth. The flowing asthenosphere carries the lithosphere of the Earth, including the continents, on its back.

g in the combustion of 0.398 mol c4h8, how many moles of o2 would be required to completely react with the fuel?
storchak [24]

41.4 grams of oxygen is essentially required for complete combustion of 3 moles of butane gas.

<h3>What is combustion?</h3>
  • Combustion is a chemical reaction that often involves the presence of oxygen and produces heat and light in the form of flames.
  • Because of the nature of the chemical reaction and the fact that more energy is produced than can be released into the surrounding medium, the rate or speed at which the reactants combine is high.
  • As a result, the temperature of the reactants is increased, accelerating the process even further.

As you know, combustion reaction is a chemical reaction in which a substance reacts with the atmospheric oxygen (O₂) to produce carbon dioxide and water. Therefore, balanced combustion reaction of butane (C₄H₁₀) will be as follows:

C₄H₁₀+\frac{13}{2}O₂→4CO₂+5H₂O

You can observe in the above reaction that, \frac{13}{2} moles of oxygen are required for combustion of 1 mole of butane.

Therefore, going by unitary method, for complete combustion of 3 moles of butane, (\frac{13}{2}×0.398) moles of oxygen would be required.

Now, we know, number of moles = \frac{Given mass}{Molar mass}

Molar mass of oxygen is 16 g/mol

We need to find a given mass which is the mass of oxygen required when the number of moles is equal to 2.59.

Thus, given mass of oxygen or mass of oxygen required = number of moles of oxygen × molar mass of oxygen

Mass of oxygen required = 2.59 moles × 16 g/mol = 41.4 g.

Hence, 41.4 grams of oxygen is essentially required for complete combustion of 3 moles of butane gas.

In a distillation operation, the heat added to the boiler a) increases with increase in reflux ratio b) decreases with increase
Leni [432]

Answer:

a) increases with increase in reflux ratio

Explanation:

If we increase the reflux ratio, which can de defined as : L/D = Condesate back to column /distillate discarded from column, it means that we increase the amount of condensate back to column. So the reboiler load will increase and be maximum in case of Total reflux ratio. And as vapor load will be increased, diameter of column will be increased too.
