makkiz [27]

Answer: 2372Kev

Eg = 2222keV

Eex = ?

Eex - Eg = 150keV

Eex - 2222 = 150

Eex = 150 + 2222

Eex = 2372keV

Explanation:

The energy possessed by the deuterium particles in their ground state or unexcited state is Eg and in that in their excited state is Eex

Describe how the words Science and optics would appear when viewed in a plane mirror?
Gre4nikov [31]

Answer:

Lateral inversion will occur in a plane mirror.

Explanation:

When words are displayed in a plane or flat mirror, the result is that if the words are displayed left, they change to right and if they were normally displayed right, they change to left. This phenomenon is known as lateral inversion. So, this will apply to the words, Science and optics. Only the sides will be interchanged.

A plane mirror reflects light, therefore, the image that is produced by it remains the same size. The image produced will not appear upside down. Only the sides will be interchanged.

How many moles if MgCl2 are there in 340g of the compound?
Marysya12 [62]

Hi!


The answer would be ~ 3.58


<h3>Explanation</h3>

You will need to use the simple formula of finding the number of moles, given the mass of the compound, which is:

number of moles of compound = mass of compound / Mr of compound

The mass in this equation is the mass of the compound you have/ are considering.

The Mr is the sum of the atomic masses of each element in the compound.


<u><em>To proceed with this, you need to have two of the following values:</em></u>

Mass : 340g

Mr of MgCl2 : 95

Number of moles : ?


<u><em>Substituting the respective values in the equation:</em></u>

number of moles = mass / Mr

number of moles = 340 / 95

number of moles = 3.58


Hope this helps!
