Answer:
B)Stabilizes the body
...........................
Answer:
The answer is
<h2>686.01 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume of zinc = 96.08 cm³
density = 7.14 g/cm³
The mass is
mass = 96.08 × 7.14 = 686.0112
We have the final answer as
<h3>686.01 g</h3>

Answer:
Only dichloromethane will be present as bottom layer and other given solvents will be present as top layer in an aqueous extraction.
Explanation:
Whether the aqueous layer would be present on top or bottom, is decided by densities of the solvent.
Solvent which is less denser than water will be present as top layer in aqueous extraction and solvent which is more denser than water will be present as bottom layer.
Therefore,
a) Methanol is less dense than water, hence will be present as top layer in an aqueous layer.
b) Hexane is less dense than water, hence will be present as top layer in an aqueous layer.
c) Benzene is less dense than water, hence will be present as top layer in an aqueous extraction.
d) dichloromethane is more dense than water and hence will be present as bottom layer in aqueous extraction
e) diethyl ether is less dense and will be present as top layer in an aqueous layer.
So, only dichloromethane will be present as bottom layer and other given solvents will be present as top layer in an aqueous extraction.
