What is the resultant molarity of 20mL of a 3.5M solution is diluted to 100mL? Will mark brainliest

Chemistry

4 0

Answer:

The resultant molarity is 0,7 M.

Explanation:

A dilution consists of the decrease of concentration of a substance in a solution (the higher the volume of the solvent, the lower the concentration).

We use the formula for dilutions:

C1 x V1 = C2 x V2

3,5 M x 20 ml= C2 x 100ml

C2= (3,5 M x 20 ml)/100ml

<em>C2= 0,7M</em>

Define the ground state of an atom
kap26 [50]

Explanation:

The nucleus of an atom is surround by electrons that occupy shells, or orbitals of varying energy levels. The ground state of an electron, the energy level it normally occupies, is the state of lowest energy for that electron. There is also a maximum energy that each electron can have and still be part of its atom.

How can modeling crustal deformation of Earth by plate tectonics be used to analyze and hypothesize the causes of earthquakes?
Rasek [7]

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.

An astronomer is a guest speaker at your school. She states that iron is the very last product in stellar fusion. Why would she
Zarrin [17]

Iron is the very last product in stellar fusion is that; Iron has a tightly bound nucleus, and atoms larger than iron are less stable and tend to undergo nuclear fission.

The stability of an atom is dependent on the binding energy per nucleon of the atom.

The binding energy per nucleon of elements increases steadily until iron, we can see that from the curve very easily.

Beyond iron, we have exceeded the region of stable binding energy per nucleon of atoms. The atoms after iron in the curve are mostly unstable heavy nuclei.
