Salt, Sugar, Aluminum, and distilled water
This question is rather easily answered if you answer using only elements: Hydrogen, Helium, Carbon, Gold, Silver, Oxygen, Nitrogen, Argon, Calcium, Potassium, etc.
Here are a few pure substances that are not elements, rather compounds: Methane, carbon monoxide, carbon dioxide, pure water and table salt (sodium chloride).
A pure substance is a material that is not mixed with anything else. All elements on the Periodic Table are pure substances.
ex: hydrogen, nitrogen, iron, gold, Mercury, tin, etc.
Water
Pure substance can be identified as either elements or compounds. Some examples of pure substance that are elements are sulfur and tin. Pure substances that are compounds are sugar and salt.
Examples of pure substance: gold, silver, carbon dioxide, hydrogen
Foods are not pure substances.
Salt. Carbon, if you have a carbon filter for your fish tank.
Water is a compound. A pure metal is an element. Graphite (a pencil lead) is the element carbon. These are all examples of a pure substance.
Salt. Carbon, if you have a carbon filter for your fish tank.
Some are flammable and some are not. This depends on the chemical properties of the individual substance. Nonflammable pure substance include helium, water, and gold. Flammable pure substances include hydrogen, hexane, and magnesium.
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.
A pure substance is a substance that cannot be separated by means of physical separation but only by chemical. It is a change in time.
pure substance, propanone
Medals are seldom struck from any pure substance, they are usually alloys of some kind
