In ethanol a hydrogen bond is formed between the oxygen of ethanol and one H-atom of water. It is also believed that ethanol is associated through internal H-bonding between their molecules and this is encouraged by the +I effect of the alkyl group of the alcohol which transfers the electronegativity towards the H- of -OH group.
It is also found that solubility decreases with increase of molecular weight. There are three types of forces which determine the extent of solubility of a solute in a solvent - (1) solute-solute ; (2) solvent-solute and (3) solvent-solvent. If the solute-solvent attractive force is greater than the other two, the solute remains in solution.
In ethanol, the force (1) overcomes the force (2) as compared to glycerol where +I effect of alkyl group is absent. Thus, the latter is more soluble in water than the former.
yes, it is much more soluble in ethanol than in water.

Yes, ethanol belongs to the alcohol functional group therefore polar, and BaCl2 is polar, so it does dissolve.
definitely more soluble in water....

Sodium chloride is very soluble in water. For ethanol the term soluble is not so adequate: water and ethanol are totally miscible.

Practically insoluble in water, in glycerol, and in propane-1,2-diol, but soluble in varying proportions in certain organic solvents, depending upon the ethoxyl content. Ethyl cellulose containing less than 46-48% of ethoxyl groups is freely soluble in tetrahydrofuran, in methyl acetate, in chloroform, and in aromatic hydrocarbon ethanol mixtures. Ethylcellulose containing 46- 48% or more of ethoxyl groups is freely soluble in ethanol, in methanol, in toluene, in chloroform, and in ethyl acetate.

of course
The polar end of the molecule is soluble in water (hydrophilic) and water solutions (including cytoplasm); the other, fatty-acid end is soluble in fats(hydrophobic).Read more: phospholipid
It depends on the substance it is put in.
Iodine is much more soluble in ethanol than in water, so it will usually form a homogeneous mixture. Of course, if you add more solid iodine than will dissolve in your quantity of ethanol at the temperature at which you are working, the excess solid will sink to the bottom. In that case, you have a heterogeneous mixture.
Ethanol---it has stronger intermolecular forces due to its ability to hydgrogen bond (because it has an -OH group) that propane. Both of them have similar dispersion forces because they have around the same number of electrons, so the presence of hydrogen bonding in ethanol will give ethanol the greater intermolecular forces and hence the higher surface tension.
