Answer:
So where then did all the carbon that living organisms are built of come from? It turns out that most of the carbon we use today came from a collision with another smallish planet about 4.4 billion years ago.
2NH3 is equivalent to N2 + H6 since the 2 at the beginning gets distributed to both atoms. Knowing this you can rewite the equation as
H2 + N2 = H6 + N2
The N2 can cancel out leaving
H2 = H6
You now have to ask ‘2 times what equals 6?’ The answer is obviously 3 at this point.

Answer:
Dispersion of white light by a prism
Explanation:
When white light is passed through a prism, the white light separates into its component wavelengths which are:
Red
Orange
Yellow
Green
Blue
Indigo
Violet
Together, all of these wavelengths constitute the spectrum of white light.
Hence, the dispersion of white light shows that each color of visible light has a specific wavelength.
