How can modeling crustal deformation of Earth by plate tectonics be used to analyze and hypothesize the causes of earthquakes?

Chemistry

Rasek [7]3 years ago

Explanation:

Modeling crustal deformation is a very important process that helps to study plate interaction that clearly can be used to predict the likelihood of an earthquake.

Earthquake is a sudden displacement or movement with the earth that transmits elastic energy.

  • Earthquakes can have shallow or deep focus depending on their location and the terrain.
  • Movement on the earth are mostly noticeable along plate margins.
  • This results in a world-wide movement of the broken slabs of the earth moving on the weak asthenosphere.
  • It is impossible to go deep within the lithosphere to identify unstable earth.
  • The uneven distribution of stress is very important in this process.
  • As plate moves, the lithosphere deforms creating stresses in some area and relieving other places of stress.
  • Continuous collection of stress data using strain mapping gives important parameters that can be modeled.
  • Areas with high amount of stress and more movement have the highest tendency of producing earthquakes.
  • A computer model is used to carry out this prediction.
  • Some other factors contributes to the rapid movement but stress are by far the most important of all.
  • By this, we can easily and readily hypothesize the causes of an earthquake and possible measures to mitigate it.

Question 23
Schach [20]

Answer:

Option B. 0.136 g

Explanation:

The balanced equation for the reaction is given below:

2AgNO3(aq) + 2NaOH(aq) —> Ag2O(s) + 2NaNO3(aq) + H2O(l)

Next, we shall determine the masses of AgNO3 and NaOH that reacted and the mass of Ag2O produced from the balanced equation. This is illustrated below:

Molar mass of AgNO3 = 108 + 14 + (16x3) = 170g/mol

Mass of AgNO3 from the balanced equation = 2 x 170 = 340g

Molar mass of NaOH = 23 + 16 + 1 = 40g/mol

Mass of NaOH from the balanced equation = 2 x 40 = 80g

Molar mass of Ag2O = (108x2) + 16 = 232g/mol

Mass of Ag2O from the balanced equation = 1 x 232 = 232g

Summary:

From the balanced equation above,

340g of AgNO3 reacted with 80g of NaOH to produce 232g of Ag2O.

Next, we shall determine the limiting reactant. This can be obtained as follow:

From the balanced equation above,

340g of AgNO3 reacted with 80g of NaOH.

Therefore, 0.2g of AgNO3 will react with = (0.2 x 80)/340 = 0.047g of NaOH.

From the calculations made above, only 0.047g out of 0.2g of NaOH given, reacted completely with 0.2g of AgNO3. Therefore, AgNO3 is the limiting reactant and NaOH is the excess reactant.

Now, we can calculate the mass of Ag2O produced from the reaction of 0.2g of AgNO3 and 0.2g of NaOH.

In this case, we shall use the limiting reactant because it will produce the maximum yield of Ag2O as all of it is used up in the reaction.

The limi reactant is AgNO3 and the mass of Ag2O produced can be obtained as follow:

From the balanced equation above,

340g of AgNO3 reacted to produce 232g of Ag2O.

Therefore, 0.2g of AgNO3 will react to produce = (0.2 x 232)/340 = 0.136g of Ag2O.

Therefore, 0.136g of Ag2O was produced from the reaction.

masya89 [10]

Answer:

A

Explanation:

In all the other options either Carbon has more than 4 atoms attached or less than 4.

Carbon can not form more than four bonds. It can only share 4 electrons .

In other option C, No H-atom is linked in the right most Carbon.

whereas according to the definition of Hydrocarbon it should have been a Hydrogen atom.
