Given what we know, we can confirm that if you aimed light from the magenta part of the Horsehead Nebula through a spectrograph we would be able to determine more precisely the structure and details of the cloud.

<h3>How do we use Spectrums in order to understand stars?</h3>

The spectrums recorded by scientists, such as those of stars or nebulas like the horsehead nebula can tell us a great deal about the composition of said entities. Studying the spectrum can tell scientists about the chemical composition of stars or nebulas, such as information about the elements that form them, like their temperatures and densities.

<h3 /><h3>How would a discontinuous emission of hydrogen gas look in the spectrum?</h3>

This would appear as pauses in the lines of the spectrum. If the emission of the hydrogen gas were constant, there would be a continuous line on the spectrum graph to indicate the illuminated hydrogen, though if this line were discontinuous, we would be able to assume that its source is emission from another gas instead.

Therefore, we can confirm that spectrography is an essential part of scientific discovery pertaining to our universe. It allows us to study the chemical composition of stars and nebulas, and determine the sources of certain emissions like that of hydrogen gases.

What happens when gases change to plasma?
IgorLugansk [536]

Answer:. In the case of neon, it is electrical energy that pulls the electrons off.

explanation-Plasma can be made from a gas if a lot of energy is pushed into the gas. In the case of neon, it is electrical energy that pulls the electrons off. When it is time to become a gas again, just flip the neon light switch off. Without the electricity to energize the atoms, the neon plasma returns to its gaseous state.

What is the molarity of a NaOH solution if 28.2 mL of a 0.355 M H2SO4 solution is required to neutralize a 25.0-mL sample of the
Anni [7]

Answer:

A) 0.801

Explanation:

The reaction that takes place is:

  • 2NaOH + H₂SO₄ → Na₂SO₄ + 2H₂O

First we c<u>alculate the H₂SO₄ moles that reacted</u>:

  • 0.355 M * 28.2 mL = 10.011 mmol H₂SO₄

Now we <u>convert H₂SO₄ moles to NaOH moles</u>:

  • 10.011 mmol H₂SO₄ * \frac{2mmolNaOH}{1mmolH_2SO_4} = 20.022 mmol NaOH

Finally we <u>calculate the molarity of the NaOH solution</u>:

  • 20.022 mmol NaOH / 25.0 mL = 0.801 M

So the answer is option A.
