Mixtures are composed of variable proportions of molecules and atoms. The composition of a mixture is variable with each components retaining its characteristic properties.

Best Answer Copy Smog is known as a mixture of fog and smoke. It is a phenomenon found in places with natural fog and smoke created by industries as a result of burning of different things..

Evaporation. Evaporation is a technique used to separate out homogeneous mixtures that contain one or more dissolved salts. The method drives off the liquid components from the solid components. The process typically involves heating the mixture until no more liquid remains. Prior to using this method, the mixture should only contain one liquid.

1. First, we need to understand what is meant by deviation in a mixture. Deviation refers to the difference in behavior of a mixture compared to what would be expected based on the behavior of its individual components. Step 2/6 2. Ethanol and acetone are both polar molecules, meaning they have a partial positive and partial negative charge.

Merriam Webster defines biogas as “a mixture of methane and carbon dioxide produced by the bacterial decomposition of organic wastes and used as a fuel.” Biogas is a renewable energy source produced from raw materials like food waste, manure, sewage, agricultural waste, and plant material.

2HCequivCH+5O(2)rarr4CO(2)+2H(2)O+"Heat" When ethyne is burnt in air, it gives a sooty flame. This is due to incomplete combustion caused by limited supply of air. However, if ethyne is burnt with oxygen, it gives a clean flame with temperature 3000^(@)C because of complete combustion. This oxy-acetylene flame is used for welding. It is not possible to attain such a high temperature without.

Examples include brass, bronze, steel, and sterling silver. Sometimes multiple phases exist in alloys. In these cases, they are heterogeneous mixtures. The two types of mixtures are distinguished by the size of the crystals that are present. Mixing together two solids, without melting them together, typically results in a heterogeneous mixture.
