Liquids have a definite volume, but take the shape of the container. Example 1. The hydrocarbon compounds and other additives that comprise them are in solution and there are no separate, individually discernable components. Assuming that the iron and sulfur are simply mixed together, it should be easy to see what is iron and what is sulfur, so this is a heterogeneous mixture. Thus . Laboratory and field studies under relevant conditions have consistently found elemental mercury present in high concentrations, however, indicating that The homogeneous kinetics under-predicted the levels of mercury oxidation observed in full-scale systems. This shortcoming can be corrected by including heterogeneous kinetics in the model calculations. A homogeneous mixture of metals is called an alloy, unless it's an alloy of mercury and another metal - in which case, it has a special name, it's called an "amalgam". Is Hydrogen an element or compound. The heterogeneous mercury reaction mechanism, reactions among elemental mercury (Hg 0) and simulated flue gas across laboratory-scale selective catalytic reduction (SCR) reactor system was studied.The surface of SCR catalysts used in this study was analyzed to verify the proposed reaction pathways using transmission electron microscopy with energy dispersive X-ray analyses (TEM-EDX) and X-ray . Technically speaking a fourth state of matter called plasma exists, but it does not naturally occur on earth, so we will omit it from our study here. Sometimes it's obvious a mixture is heterogeneous, like a stream bed of different sizes, shapes, and colors of rocks. Activity or Observation Element, compound,homogenous or heterogeneous mixture? Chemical elements can be homogeneous. Any given spoonful of soup will contain varying amounts of the different vegetables and other components of the soup. Vegetable soup is a heterogeneous mixture. Compared to homogeneous reactions, heterogeneous interactions are dominant for mercury oxidation in coal-fired flue gas , . A heterogeneous mixture is a mixture in which the composition is not uniform throughout the mixture. It retains its composition and properties. Thank you; Question: Q1:Identify if each is a element, compound, heterogeneous mixture or homogeneous mixture. Can be separated by physical means.
