Do you observe the halide test in the upper layer or lower layer?
upper layer
Which is the hexane layer?
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.
Is the bottom layer water or bromoform?
The lower layer is Bromoform, tribromomethane CHBr3 with the highest density (2.889 g/cm3), almost three times greater than of water.Trick:To simply find out if water is the lower or upper layer in a two-layer fluid system, you canadd carefully one drop of water at the top of the liquidwatch accurately the path of the falling drop and when it does 'dissolve'Then:when going down through the upper layer, then it will 'dissolve' in the lower, you may conclude the upper layer is NOT water. Orwhen 'dissolving' immediately in the upper layer then you'll conclude the upper layer is water.
When dichloromethane is mixed with water will the organic phase be in the upper level or lower level?
Dichloromethane (methylene chloride) has a higher density than water. It will settle to the bottom of a dichloromethane:water mixture. Is this what you are asking?
Explain briefly how you would separate chloroform or dichloromethane extract from an aqueous solution using a separating funnel?
Both chloroform and dichloroform are denser than water. You will see two layer in separating funnel. The lower layer will be chloroform and upper layer would be aqueous layer.
Do you observe the halide test in the upper layer or lower layer?
upper layer
Do you observe halide in the upper or lower layer in a flame test?
upper layer
What is the purpose of separating funnel?
- Ability to separate at least two immiscible liquids from each others. - It can be operated easily and rapidly - It is transparent to observe different layers easily. - The upper layer or the lower layer can be selectively removed. The upper layer is removed by the stopper and the lower by the stopcock.
Is the second layer of the earth the upper mantle or the lower mantle?
upper mantle
What is the lowere level of the ozone called?
The ozone is a single layer. There is no upper and lower layer.
What is the difference between lower and upper epidermis?
mesophyll layer
How far down a narwhal goes?
They normally stay in the upper, sunlit layer but sometimes they can go uo to the upper lower layer to get food.
Which is the hexane layer?

What determines which solvent is on the upper layer and which is on the lower layer in an immiscible liquid?
the less dense layer is on top and the more dense layer is below.
What are th four layers of cells found on plants?
This answer refers to the cell layers of a plant leaf: There's the outer cuticle, the upper epidermis, the palisade mesophyll cell, the bundle sheath cell (containing xylem and phloem) surrounded by spongy mesophyll cells and then the lower epidermis. Not sure if this helps...
When water and bromoform are mixed two layers form is the bottom layer water bromoform?
The lower layer is Bromoform, tribromomethane CHBr3 with the highest density (2.889 g/cm3), almost three times greater than of water.Trick:To simply find out if water is the lower or upper layer in a two-layer fluid system, you canadd carefully one drop of water at the top of the liquidwatch accurately the path of the falling drop and when it does 'dissolve'Then:when going down through the upper layer, then it will 'dissolve' in the lower, you may conclude the upper layer is NOT water.
