Can someone please help me with my science research I kind of need help in a few things that I listed, I’m currently working on
dalvyx [7]

Answer:

For your first question, Curium does not occur naturally on Earth, meaning that it is not produced naturally on Earth. However, it can be formed in nuclear reactors.

For your second question, Curium has been used to provide power to electrical equipment used on space missions, but doesn't seem to be that important overall.

Explanation:

Hope this helped!

Why does the nitrogen concentration decrease after hydrogen is added? n2(g)+3h2(g)⇌2nh3(g) why does the nitrogen concentration d
Leno4ka [110]

<span>The chemical reaction of a reversible reaction is actually governed by Le Chatelier’s principle. It states that when more reactants are introduced into the system, the reaction will proceed forward to create more products. So since Hydrogen is a reactant and Nitrogen is also reactant so adding more Hydrogen makes more products hence reducing the Nitrogen concentration.</span>

We observe a distant object in space and see that the spectral lines for hydrogen in the object's light appear at a shorter wave
MrMuchimi

Answer:

This tells us the radial velocity of the object and that the object is approaching or coming towards us.

Explanation:

Certain chemicals radiate with particular wavelengths or colors  when their temperature is raised or when they are charged electrically. Also observable are dark strokes separating the spectrum known as absorption lines

These spectral lines of chemicals are well known as stated above and from the phenomenon of Doppler effect, spectroscopy can be used to detect the movement of a distant object by the change of the emitted frequency of the wavelength

The Doppler effect is used in calculating the radial velocity of a distant object due to the fact that an approaching object compresses its emitted signal wavelength while a receding object has a longer wavelength than normal
