Crude oil is a mixture of short to long chain hydrocarbons.
It has to be separated into many different fractions to become usable.
It may also contain mineral impurities due to it being underground
Corn oil water is a mixture, as it consists of two different substances: corn oil and water. In this mixture, the corn oil does not dissolve in water, leading to the formation of separate layers due to differences in their densities and properties. A pure substance, on the other hand, contains only one type of material with consistent properties throughout.
Ice is solid H2O so it is a pure substance, at least ideally.
Yes, purified water is a pure substance because it consists of only water molecules with impurities removed through processes like distillation or filtration. This makes it a homogeneous mixture with a consistent composition.
Water is a compound having a chemical formula of fixed proportions, and as such is a pure substance. Its chemical formula is H2O, in which the two hydrogen atoms are covalently bonded to the oxygen atom.
No, sweetened water is not a pure substance because it is a mixture of water and sugar or other sweeteners. A pure substance is a single type of matter with a specific composition and properties.
No: It is a mixture.
water is pure so is homogeneous ice is pure so is homogeneous oil is pure so is homogeneous
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).
It would be an mixture
Pure Substance
Water vapor is a pure substance.
gasoline is from crude oil so it's not a pure substance
Pure substance.
For a substance to be pure, it must have no impurities in the substance. Carbonated water is water with carbon dioxide and other substances dissolved in this. Hence, it is not a pure substance.
Ice is solid H2O so it is a pure substance, at least ideally.
no , its a mixture. salt is a pure substance, as is water, but togher they are a mixture.....
A pure substance is a substance that is constant throughout. Such as water, tin or sulfur.
