A pure substance is a form of matter that has a definite composition and distinct properties. It may consist of only one type of atoms (examples: Fe(s), N2(g), S8(s)), or of only one compound where the atoms are connected in a defined way, (examples: FeS(s), CH4(g), NaNO3(s), H2O(l)).
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).
non-iodized table salt
sugar
water H20
baking soda - sodium bicarbonate
oxygen
Yes, pure water is an example of a substance that is free from impurities and contaminants.
A sealed glass vial containing pure distilled water is an example of a container filled with a pure substance. Since the vial only contains water molecules and no other substances, it is considered a pure substance.
Calcium is an example of a pure substance known as an element, specifically a metal. Carbon is also a pure substance, but it is an element that belongs to the non-metal group.

24k Gold is a pure substance. Because it is made up of just gold unlike 14k gold which is silver and gold mixed.
No, it's a mixture.
oxygen is an example of a pure substance because a pure substance is made up of one kind of matter and it cannot be broken down into smaller parts.
No. Air is not pure substance. Air has all dust and dangerous gases with it. From place to place its composition changes.
A pure substance has only one kind of particle. Sulfur is an example of a pure substance.
A sealed glass vial containing pure distilled water is an example of a container filled with a pure substance. Since the vial only contains water molecules and no other substances, it is considered a pure substance.
An example of a pure substance in everyday life is distilled water. It consists of only water molecules with no other substances or impurities present.
Calcium is an example of a pure substance known as an element, specifically a metal. Carbon is also a pure substance, but it is an element that belongs to the non-metal group.
