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.

the answer is 64 moths are dark
Answer:
The oxygen element in H2O2 is the specie that is reduced in H2O and oxidized into O2.
Explanation:
5 H2O2(aq) + 2 MnO4-(aq) + 6 H+(aq) → 2 Mn2+(aq) + 8 H2O(l) + 5 O2(g)
Oxidation is defined as the outright loss of electrons. Oxidation leads to an increase in an element's oxidation number.
If this reaction is broken down into reduction and oxidation halves
It is observed that, of the reactants above,
H202 becomes H2O and O2
MnO4- + H+ becomes Mn2+ and H2O
Oxidation number of Mn changes from +7 In MnO4- to +2 In Mn2+ (evidently reduction)
The Oxygen in MnO4- doesn't change oxidation numbers as its oxidation number stays at -2
Oxidation number of Oxygen changes from -1 in H2O2 to -2 In H2O and 0 in O2
The Hyrogen in H2O2 doesn't change oxidation numbers, itsoxidation number stays at +1 in H2O2 and H2O.
This indicates that H2O2 undergoes oxidation and reduction; more specifically, the oxygen element in H2O2 is the specie that is reduced in H2O and oxidized into O2.

The coefficients in a balanced chemical equation are important because they give the ratio of the reactants and the products.
Those ratios are fixed and when the reagents react do it in the same proportion and yield the products in the same proportion of the coefficients.
Then, the coefficients are the basis for the calculations of the amount of substances that react and the amount of substances that are formed as result of the reaction.
