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.
One substance with a specific gravity less than water is oil. This is why oil tends to float on top of water.
A substance that cannot be broken down is a pure substance
Water is not an element, it is a compound composed of hydrogen and oxygen.
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.
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.
An element - substance - NOT a mixture.
