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.

Compare the weight of a 100-lb person on Mercury with the weight of that same person on Jupiter. What can you conclude about the
tatiyna

Answer:

if you weigh 100 pounds on Earth, you would weigh only 38 pounds on Mercury. That's because Mercury weighs less than Earth, and therefore its gravity would pull less on your body. If, on the other hand, you were on heavy Jupiter, you would weigh a whopping 253 pounds!

Please help me with this net ionic chem question. I’ll mark you brainiest if you know it.
rjkz [21]

Answer:

B: 3k+ + 3OH¯ + Fe3+ + 3KOH = Fe3(H) + + 3NO3¯

Explanation:

Potassium hydroxide (KOH) reacts with iron (III).

The normal balanced equation is;

Fe(NO3)3 + 3KOH = Fe(OH)3 + 3KNO3

Now the ionic equation will be;

3k+ + 3OH¯ + Fe3+ + 3KOH = Fe3(H) + + 3NO3¯

What is the slope of an Arrhenius plot for the following reaction? 2NOCl → 2NO + Cl 2 Picture
ZanzabumX [31]

Answer:

c. −1.22 × 10^4 K

Explanation:

Generally, the slope of an Arrhenius plot can be determined either from the graph of In k against 1/T or the available experimental data of the rate constant (k) and the absolute temperature. Mathematically,

slope = \frac{ln k_{2} -ln k_{1} }{\frac{1}{T_{2} }-\frac{1}{T_{1} }   }

Where:

k_{1} = 6.6*10^-4 L/(mol.s)

k_{2} = 2.9*10^-1 L/(mol.s)

T_{1} = 400 K

T_{2} = 500 K

slope = (ln 2.9*10^-1 - ln 6.6*10^-4)/(1/500 - 1/400)

slope = (-1.238+7.323)/(0.002-0.0025)

slope = 6.085/-0.0005 = -1.22*10^4 K
