Petroleum Ether is a mixture of different hydrocarbon compounds, and oil is also made of long hydrocarbon chains. The two chemically similar compounds form many van der waals interactions (like dissolves like) to create a homogenous solution.
Oil molecules do not contain any charge. Oil is comprised of long chains of hydrogen and carbon atoms linked to each other and does not carry any net charge. So, salt and oil are not "chemically alike." One is charged, the other is not
yes
No. Oil will dissolve in fatty (hydrophobic) liquids, not in hydrophilics like water.
Petroleum ether is a type of petroleum mixture. It contains hexanes and pentanes and is a type of nonpolar solvent.
Because the oil has a nonpolar molecule and water has a polar molecule.
Yes, it is very much soluble in Hexane, diethyl ether, Petroleum spirit etc
Pack a new oil pump with petroleum jelly. This will create a suction when the pump starts up and suck oil in. The jelly will dissolve in the oil harmlessly.
Oil does not dissolve in water. It stays there forever and ever. I'm sure everybody has done the shaking of the salad dressing thing, but it still comes back on top. That is the closest oil becomes to dissolving in water :P
it is the concept of like dissolves like. ethers are more non-polar therefore will dissolve non polar solutes. Alcohols depending on the size of the chain will be polar or non polar shorter chain alcohols will not dissolve well in ether while non-polar ones would dissolve more readily.
Petroleum isn't a single product, but rather a range of substances. Many will float on water, but not all.
Oil and petroleum are the same thing.

Oil and Petroleum use is very efficient.
