Give me some examples of pure substances in everyday life?
Pure substances are made up of a single element, or a single compound. Table salt is a pure substance because it is made up of only the compound NaCl (sodium chloride). Diamond is a pure substance, it is made up of the element carbon. Air is not a pure substance, it is a mixture of several gaseous elements and compounds (nitrogen, oxygen, carbon dioxide..) Distilled water is a pure substance made up of a single compound H2O.
Condition in which molecules of a substance are spread evenly throughout a space?
Difusion in air. Osmosis in water.
What are some examples of Homogenous mixture?
A homogenous mixture is a mixture of substance where the substance is so evenly mixed you cannot see the different parts that make it up. Some examples, of a homogenous mixture could be table salt and table sugar. However, some mixtures can also be gases or liquids. Brass and the air we breathe are also some examples. :)
