A chemical element is homogeneous only if it is monoisotopic; but in practice this aspect is neglected.
A chemical element is not a "change".
no, it is an element. therefore, can neither be homogeneous nor heterogeneous
Arsenic is a chemical element with the symbol As, atomic number 33.
Chromium is a chemical element that is naturally found as a solid in its metallic form. It is considered a homogeneous substance because it has the same uniform composition throughout its structure.
NO!!! Elements and compoounds exists as separate entities. Heterogeneous means a mixture of substances that are in different physical states. Compare to Homogeneous which means a mixture of substances that are in the SAME physical state. However, The element bromine(Br) is liquid at STP. The compound water(H2O) is also a liquid at STP. When mixed together to form bromin water, it is an homogeneous mixture.
Homogeneous
Toluene is a chemical organic compound.Sulfur is a chemical element.
Manganese is a chemical element that typically exists as a pure substance, so it is homogeneous. This means that all samples of manganese should have uniform properties, such as composition and physical characteristics.
Mercury is a chemical element not a mixture.
Sulfur is an element and therefore a homogeneous substance.
Oxygen is a chemical element not a mixture.
A salt is a chemical compound.
Sugar is a chemical compound.
Methane is a chemical compound - CH4.
Ethanol is an organic chemical compound - C2H5OH.
Well, iron fillings can't really be a mixture, since there aren't two different substances here. ________________________ But to answer the question- 1. Iron Filings are homogeneous as they are of the same or similar kind (from the definition of homogeneous). 2. They are a homogeneous substance being a physical material which has discrete existence (from the definition of substance).
Heterogenous
no, it is an element. therefore, can neither be homogeneous nor heterogeneous
