by definition, no -- because a compound is a chemically-bonded material at the atomic level, and a mixture by definition is "more than one element or compounds combined that do NOT form a chemical bond".
Salads and soil are mixtures, while sugar is any of several hydrocarbon compounds. As a group, they are examples of "agricultural items that begin with the letter S."
Yes, besides elements and compounds, matter can exist in form of mixtures.
No: Compounds are simple mixtures of substances
A compound comprises the same proportion of its components, a mixture can be made up of varying amounts.A compound may have physical and chemical properties which are quite different to those of any of its components. A mixture retains many of the physical and chemical properties of its main ingredient.
A compound contains two or more elements and so does a mixture.
Helium doesnot form any compounds.
In the strictest chemical sense a compound is the term for a molecule, a compound of elements. Sugar, salt and water are examples of compounds. As such compounds have the qualities of consistent color, well defined physical properties (such as melting or boiling point). Compounds cannot be separated because they are of a uniform structure. Homogeneous mixtures are similar to compounds only in appearance. Thus a mixture of sugar and salt may not be discernible from samples of either simply by sight. A better example would be to consider a solution of salt and water. Solutions are also homogeneous mixtures. A saline solution is visually indiscernible from water. In a broader definition, any mixture can be referred to as a compound- if the mixture has a consistent appearance, the two are the same.
Mixtures can be combinations of elements or compounds. Examples include mixing salt and water, sand and iron filings, or oil and vinegar. A mixture consists of two or more substances physically combined, each retaining its own properties.
Helium does not form any compound.
Elements and compounds are pure substances. They cannot be broken down further by physical and/or chemical means. Mixtures, on the other hand, are physical combinations of pure substances . A compound is when two or more different types of elements are chemically bonded but a mixture is when there is different types of elements that is not chemically bonded but physically bonded.
Any mixture that looks the same throughout such as salt water (mixed well). Things such as oil mixed with water would not be because the non-polar oil will not disolve in the polar water or vice versa.
Compounds are substances made of two or more elements chemically bonded together in a fixed ratio, while mixtures are combinations of two or more substances that are physically mixed together but not chemically bonded. Compounds have specific properties and can only be separated by chemical reactions, while mixtures can be separated by physical means like filtration or distillation.
