Answer:
Option D. Saturated alkane
Explanation:
To know which option is correct, it is important that we know what saturated and unsaturated compounds are in this context.
Saturated hydrocarbons are compounds which has only carbon to carbon single bonds (C–C) in its chain. A very good example of such compound is the Alkanes.
Unsaturated hydrocarbons are compounds which has either a carbon to carbon double bond (C=C) or a carbon to carbon triple bond (C≡C) in its chain. Examples of such compounds include alkenes and alkynes.
Now, let us answer the question given above bearing the meaning of saturated and unsaturated compounds in mind.
The compound given above contains only carbon to carbon (C–C) single bond.
Therefore, the compound is a saturated alkane.
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.

Answer:
c
Explanation:
because u need the energy to be able to work
<span>Distillation, filtration, evaporation are some of the techniques by which mixtures can be resolved into their components.Distillation is the process of separating the component or substances from a liquid mixture by selective evaporation and condensation.Filtration is any of various mechanical, physical or biological operations that separate solids from fluids (liquids or gases) by adding a medium through which only the fluid can pass.Evaporation is a type of vaporization of a liquid that occurs from the surface of a liquid into a gaseous phase that is not saturated with the evaporating substance.</span>
Answer:
0.04838J
Explanation:
Heat is a form of energy that is transferred from one body to another as the result of a difference in temperature between the bodies , here heat is added to the water as a result of temperature change of 0.364 degreesC
Given:change in temperature=0.364
Mass of water=0.0318g
But we need specific heat capacity of water which is
4.2 J/g°C
Then we can calculate How much heat is added by using below formula
Energy = Mass * specific heat capacity *(change in temperature)
energy =0.0318g* 4.18g*0.364
=0.04838J
