What are the differences between a mixture and a compound?
assistant
Mixture and compound are two terms used to describe different combinations of materials. A mixture is a blend of two or more materials in which each material keeps its individual chemical properties. This means that the materials are usually physically separated, and can be separated back out again relatively easily. A compound, on the other hand, is a combination of two or more materials that are bonded together chemically, producing a new material that has different properties than the original materials. Compounds cannot be separated back into their individual components without a chemical reaction.
