Answer:
B.red
Explanation:
Electromagnetic spectrum is range of the frequencies and their respective wavelengths of the various type of the electromagnetic radiation.
In order of the decreasing wavelength the spectrum are:
Red , Orange, Yellow, Green, Blue, Indigo, Violet
Increasing wavelength is the opposite trend. Thus, The longest visible wavelength is red and the shortest is violet.
Also, Violet light gets scattered the most while the red light gets scattered the least.
During the time of the sunset, the Earth is rotating away from the Sun. Thus, most of the light colors scatters in the ways and the color that least scatter which is red reaches the Earth.
That's why, at the time of sunrise and sunset, the sky looks red.
Answer:
Prompt Neutrons
Explanation:
Principle. Using uranium-235 as an example, this nucleus absorbs thermal neutrons, and the immediate mass products of a fission event are two large fission fragments, which are remnants of the formed uranium-236 nucleus. These fragments emit two or three free neutrons (2.5 on average), called prompt neutrons.
Answer: The molecular formula will be 
Explanation:
If percentage are given then we are taking total mass is 100 grams.
So, the mass of each element is equal to the percentage given.
Mass of C= 13.65 g
Mass of F = 86.35 g
Step 1 : convert given masses into moles.
Moles of C =
Moles of F=
Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.
For C = 
For F = 
The ratio of C : F= 1: 4
Hence the empirical formula is
The empirical weight of 
= 1(12)+4(19)= 88g.
The molecular weight = 88.01 g/mole
Now we have to calculate the molecular formula.
The molecular formula will be=
If they are miscible, they will mix together. They don't necessarily make a new compound. It is sort of like a dilution problem. You can mix say water and antifreeze. You don't get a chemical reaction.
No solidification occurs.
There are no layers.
There is no chemical reaction.
Answer: they will form a solution
