Bromide Solution
Bromine
In a Halide Test, you can add an unknown solution into a test tube and add hexane solution plus several other solutions called by the procedure. Shake the test tube and record the upper hexane layer. So the answer would be hexane is present in the upper layer.

Hexane is almost insoluble in water (Solubility = 9.5 mg per liter). With a density of 0.66, hexane is much lighter per unit of volume than water, which has a density of 1.0, so that when mixed, they will separate and the hexane will be on the top, leaving only a very small amount in the water layer (1.44% by volume). The upper hexane layer will also contain a little water (about 0.002% by volume)

Yellow cake mix already has yellow food coloring in it, which will effect any colors added. This should be no problem when adding green coloring, but the red will be tinted slightly orange. You might want to start with a white cake mix, which would give truer colors when dyed.
the solution turns red and splits into two colours, red on top and yellow on bottom; after standing the top (red) layer turns colourless and opaque but there is no real reaction.
Yes. If you put water and hexane in a beaker or a container together, the hexane will be on top of the water. One way to see this is to dye the water. They do not mix because water is polar and the hexane cannot dissolve in it. It is on top because, guess why? It is less dense than water. That is why anything floats on water... it is less dense! Hope that answers your question!
The different layers of the sun are yellow ,orange and red but there is also some white ! 2nd Answer: Not even close . . . The Sun is a bluish white-hot all the way through. The Sun may look yellow, orange, and red when there is dust and pollution between it and your eye.

Let's see. An orange is roughtly spherical, an orange color, and a relatively smooth, but irregular exterior. When you peel it, this yellowish stuff gets on your hands that is really bitter. Inside, there is a white layr past the orange layer, and the white layer is actually sort of tasty. It is thicker on some oranges, and thinner on others. I prefer it thick. once you get to the center there are slices of orange that are delicious and packed with vitamin C. When you bite into one, the juice of the orange is released while still offering plenty of pleasurable chewing texture.
