A mixture of oil and water is a mixture, not an element. If by substance you mean not a pure substance (element or compound), then oil and water would be a substance (that is a mixture). If you mean oil and water separately, then oil is a mixture of hydrocarbons, and water is a compound (pure substance).
One substance with a specific gravity less than water is oil. This is why oil tends to float on top of water.
Water is not an element, it is a compound composed of hydrogen and oxygen.
No, oil does not contain water. Oil and water are immiscible, meaning they do not mix together. Oil is a hydrophobic substance, which means it repels water.
Oil soluble means that a substance can dissolve in oil. When a substance is oil soluble, it can mix well with oils and fats, but not with water. This affects the properties of the substance by making it more compatible with oil-based products and less likely to mix with water-based substances.
Hydrophobic.
Oil and water are both compounds, not elements.
Only elements are in the periodic table (about 100) but oil is not an element, it is a substance.
A substance that cannot be broken down is a pure substance
One substance with a specific gravity less than water is oil. This is why oil tends to float on top of water.

water+coal=oil
No, oil does not contain water. Oil and water are immiscible, meaning they do not mix together. Oil is a hydrophobic substance, which means it repels water.
Oil is insoluble in water because it is a nonpolar substance, while water is a polar substance. This means that oil molecules do not mix or dissolve in water, leading to the separation of the two substances.
Oil soluble means that a substance can dissolve in oil. When a substance is oil soluble, it can mix well with oils and fats, but not with water. This affects the properties of the substance by making it more compatible with oil-based products and less likely to mix with water-based substances.

water and oil
No. An element is made up of only one type of atom. Water and oil are made up of many different types of atoms, so they do not form an element.
