Explain how the processes that occur at mid-ocean ridges and ocean trenches illustrate the cycling of matter.

Chemistry

Nimfa-mama [501]3 years ago

Explanation:

At one end, new crusts are being produced, at other end the crust is being destroyed and this strikes a unique balance.

At the mid-ocean ridges, the lithospheric plates are diverging. This is implies that the earth is pulling apart here. When the earth is pulling apart, new materials from the asthenosphere comes to the surface thereby creating new lithospheric plate.

As new plates are formed, they push back against the old one. New plates are found very close to the margin and it begins to age away from the margin.

On the other end, old plates are taken away from this center to ocean trenches. At oceanic trenches subduction is occurring.

In a subduction, the lithospheric plate plunges deep into the asthenosphere where they are being melted back.

This is a covergent margin.

This process continues in a dynamic manner to cycle matter on earth.

A researcher selects three regions X, Y, and Z, and records the types of discharge that enter the regions’ rivers.
elixir [45]

Region Z should be monitored more closely to avoid health issues.

<h3>Why region Z should be monitored?</h3>

Region Z should be monitored more closely to avoid potential health issues because region Z produces waste from chemical plants which are dangerous for our water and environment so we can conclude that Region Z should be monitored more closely in order to avoid health issues.

How to find the number of neutrons in an isotope?
Alexeev081 [22]
Chemical properties of elements are primarily determined by the electrons but not by neutrons. Therefore, the isotopes of the same element have similar chemical behavior. (a) The atomic number is 17, so there are 17 protons and 17 electrons. The mass number is 35, so there are 18 (=35-17) neutrons. Hope this helps. :)

The Bohr theory can be extended to non-hydrogen one electron ions such as He+ and Li2+, in which case the energy depends on the
Wewaii [24]

Answer:

E =  1.5 x 10⁻¹⁷ J

Explanation:

The Rydberg equation for electronic transitions in the hydrogen atom  is

1//λ = Rh x ( 1/n₁² - 1/n₂²)

where            

           Rh : Rydberg´s constant 1.09737 x 10 ⁷ m⁻¹

           n₁ : Intial energy Level

           n₂ : Final energy Level

But for non-hydrogen one electron ions  such as He+ and Li2+ ²⁺ , the equation is similar but multiplied by Z²:

     1/ λ = Rh Z² x ( 1/n₁² - 1/n₂²)

I will work this problem by fist calculating 1/λ  and then use the equation E= hc/λ  where

h : Planck´s constant  6.626 x 10 ⁻³⁴ J s

c : Speed of light 3 x 10 ⁸

1/ λ =   1.09737 x 10 ⁷ m⁻¹ ( 3² ) x ( 1/1² - 1/2² )

1/ λ =   7.4 x 10⁷ m⁻¹

E = 6.626 x 10 ⁻³⁴ J s  x  3 x 10^8  m/s x   7.4 x 10⁷ m⁻¹

E =  1.5 x 10⁻¹⁷ J
