water density (at standard temp of approx 25C and pressure of 1 atm; "STP") 1 gram per cubic centimeter, or 1 gram per milliliter (density of H2O vs T: http://www.simetric.co.uk/si_water.htm)
methylene chloride density, same conditions, 1.3266 grams per cubic centimeter, or 1.3266 grams per milliliter
Just compare the densities of both water and CH2Cl2. Water is less dense and will be in the top (aqueous) layer. CH2Cl2 is more dense and will be on the bottom (organic) layer. Density H2O = 1.00 g/cm3 Density CH2Cl2 = 1.33 g/cm3
because water is highly polar and Br2 is non-polar so the molecules in the water are more attracted to each other. But methylene chloride is non-polar so its molecules are no more strongly attracted to other methylene chloride molecules than they are to Br2 molecules. Since all of the forces are weak, the substance can dissolve.
H2O is very slightly soluble in CH2CL2 but H2O is hydrophillic and CH2Cl2 is hydrophobic therefore the two molecules dont react or bond properly resulting in a two phase solution of an aquous and organic layer containg a very small percentage of the H2O.
The vapor pressure of water decreases when mixed with sodium chloride. This is because the presence of sodium chloride particles in the water lowers the vapor pressure of the solution compared to pure water at the same temperature.
To separate ammonium chloride from a mixture of ammonium chloride and sodium chloride, you can dissolve the mixture in water to form a solution. Then, heat the solution to evaporate the water, leaving behind solid ammonium chloride due to its lower melting point compared to sodium chloride. This process is known as crystallization.
Methylene chloride is denser than water, with a density of about 1.33 g/cm^3 compared to water's density of about 1 g/cm^3. This difference in density allows methylene chloride to separate from water in a mixture due to their immiscibility.

Yes, methylene chloride is partially miscible with water, meaning it can mix with water to some extent.

Hexane is insoluble in water because it is non-polar, so it cannot form hydrogen bonds with water molecules. Methylene chloride, on the other hand, is soluble in water because it can form hydrogen bonds with water molecules due to its polar nature.
Very fast. It can be evaporated quickly at room temperature, especially in a vacuum. It is also more dense than water, and is therefore found on the bottom of a water/methylene chloride mixture.
Ethanol and water is a suitable solvent pair for recrystallization. Methylene chloride and water, as well as dimethylformamide and diethyl ether, are not typically used together as solvent pairs for recrystallization due to their different chemical properties and solubility characteristics.

1. Because the density of sodium chloride is higher than the density of water. 2. Sodium chloride is soluble in water.

The water density doesn't decrease.
Yes, the density of zinc chloride can be determined by measuring the mass of a known volume of the solution (a mix of zinc chloride and water) and then calculating the density using the formula: Density = mass/volume.
