Pure salt, NaCL, is a chemical compound made from two elements. So yes it is a combination of two pure substances
It depends. Some table salt is pure, or nearly pure, sodium chloride. An increasing amount of table salt is being sold with iodine added to it, which makes this "iodized" salt not a pure substance. Table sugar is usually pure, or nearly pure, sucrose. It's usually pure enough to be considered a pure substance. Refined sugar and refined salt (without additives or impurities) are pure substances.
salt is n a c l 2 go figure!! this is all I have on this one. I think I'm right on this one.
elements and compounds
it is important to separate and purify substances so that: 1.we can get them in their pure form. 2.to remove undesirable particles from them.
They are both compounds; They both have more than 2 atoms or substances
no because it has at least 5 substances 2 r in the name

The components of a mixture are not chemically combined and do not have a definite composition. A pure substance is either an element or a compound (in which case it is composed of elements that are chemically combined) and has a definite composition.

The 2 categories are 'pure substances' or 'mixtures'
A pure substance has only one kind of atom or molecule. A mixture has a number of different pure substances mixed together. Salt- NaCl is a pure substance Salt dissolved in water is a mixture of salt NaCl and water (H2O). Sugar is a pure substance- sucrose Sugar and cinnamon is a mixture of the 2 materials In mixtures, the individual pure components can be separated - it may be difficult but it can be done. How can you tell??? You have to stop and think about it. What kinds of materials are involved? If it is a pure component, it should only have one material/component.
chemical
Matter can be divided into two categories: pure substances and mixtures. Pure substances are made up of only one type of atom or molecule, while mixtures are composed of two or more different substances that are physically combined.
Because it contains 2 or more substances
A pure substance is a sample of matter with both definite and constant composition with distinct chemical properties. Examples: water, diamond, gold, table salt (sodium chloride), ethanol Salt water is not a pure substance because it is a mixture of two compounds, NaCl and H2O. Orange juice again is a mixture of sugar, water and orange pulp. So it is not a pure substance. Duct tape is made of three layers: Layer 1: A Resilient Plastic Layer 2: A Fabric Mesh Layer 3: Rubber Based Adhesive So it is certainly not a pure substance. Baking soda, on the other hand, is a pure substance because it is a compound (NaHCO3) and all compounds and elements are considered pure substances.
they are substances that require people to take chemical measures to separates them. in other words, you cant just separate them with a strainer or something of that sort. Examples: H2O- water NaCl- Table Salt
