1. Put the mixture in water and stir.
2. Sodium chloride is dissolved, silicon dioxide not.
3. Filter the mixture.
4. Sodium chloride passes in the solution.
5. Evaporate the water.
NaCl and SiO2 together would be considered a mixture. A mixture is a physical combination of two or more substances that can be separated by physical means. In this case, NaCl (sodium chloride) and SiO2 (silicon dioxide) do not chemically combine to form a new substance, so they are still distinct substances within the mixture.
These two compounds form a mixture because they can not react with each other under normal conditions.
It is impossible to use a platform in this platform.
Out of the substances listed, iron (Fe) would have the greatest ductility. Iron is a metal known for its high ductility property, meaning it can be drawn into thin wires without breaking. The other substances - carbon (C), silicon dioxide (SiO2), and sodium chloride (NaCl) - are not known for their high ductility.

The most common molecule on earth is SiO2.

One method to separate Fe from NaCl is by using a magnet to attract and remove the iron (Fe), as it is magnetic, while leaving the sodium chloride (NaCl) behind. This process is known as magnetic separation.
A solution of NaCl in a solvent in which the cations and anions separate, for example in water, can conduct electricity.
Among the substances listed, iron (Fe) would have the greatest ductility. Ductility refers to the ability of a material to deform under tensile stress, and metals like iron are known for their malleability and ductility. In contrast, compounds like NaCl (sodium chloride) and SiO2 (silicon dioxide) are brittle and do not exhibit significant ductility. Carbon in the form of graphite (C(s)) has some ductility, but it is generally less ductile than iron.
Salt is used to separate DNA.
Two methods are: - distillation - crystallization/recrystallization
