No.
If it's "pure" it's not a mixture.
They are homogeneous. But they are not a mixture, so they are a pure substance
Tap water is a homogeneous mixture, which means it has a uniform composition throughout. It is a mixture of water molecules along with dissolved minerals, gases, and other compounds, but these components are evenly distributed.
Distilled water is a homogeneous mixture because it is a mixture of water molecules with consistent properties throughout. There are no visible differences or variations in composition within the solution.
Tungsten is a pure element and not a mixture, so it is considered a homogeneous substance.
seawater is a homogeneous mixture. The water being the solvent and the salt being the solute. A heterogeneous mixture is mixed but not as thoroughly as a homogeneous mixture. None of these though are chemically combined, none are compounds. (hence mixture)
Homogeneous mixture
Homogeneous mixture
Pure water (H2O) is a chemical compound; if the water is impure may be a homogeneous or heterogeneous mixture.
They are homogeneous. But they are not a mixture, so they are a pure substance
Silver is not a homogeneous mixture or a heterogeneous mixture, it is a pure element. Silver does appear in homogeneous mixtures and heterogeneous mixtures such as sterling silver and silver nitrate.
Tap water is a homogeneous mixture, which means it has a uniform composition throughout. It is a mixture of water molecules along with dissolved minerals, gases, and other compounds, but these components are evenly distributed.
Heterogeneous vs. homogeneous refers to solutions. Pure water is a compound which is bound together chemically. Solutions are combined physically. So technically it is neither.
pure substance
Pure air is homogeneous because all components are completely miscible.
no
Ca is an element. It is a pure substance, which, by definition, is homogeneous matter, but is not a mixture.
