NaCl in water is a mixture.
Salt is a compound because Sodium is a metal with a plus 1 charge, while chloride is a nonmetal with a minus 1 charge. A mixture would be a combination of different compounds or molecules, while a solution is a suspension of ions in water or some other solvent.
air is a mixture of elements (nitrogen, oxygen, trace amounts of other elemental gases) plus compounds (water vapor, nitrogen and sulfur oxides, CO2)
Concrete is a composite construction material, composed of cement (commonly Portland cement) and other cementitious materials such as fly ash and slag cement, aggregate (generally a coarse aggregate made of gravel or crushed rocks such as limestone, or granite, plus a fine aggregate such as sand), water and chemical admixtures.
An example is water plus oil.
No, In the United States, in order for a vanilla extract to be called pure, the U.S. Food and Drug Administration requires that the solution contain a minimum of 35% alcohol and 13.35 ounces of vanilla bean per gallon.
Sodium chloride and water form a solution, a homogeneous mixture not a compound.
Not, its a homogeneous solution (a mixture).
Yes. When NaCl is added to water, it forms a solution, which is a homogeneous mixture.
When NaCl (sodium chloride) and KNO3 (potassium nitrate) are mixed together, no chemical reaction occurs as each compound remains as separate ions in solution. This is known as a physical mixture or a non-reactive mixture.

You mean mixture. A mixture is a physical combination. Think salt in water. A compound is a chemical combination. Think Hydrogen plus Oxygen makes water.

Neither sugar (table) nor water are elements but are compounds. Mixing them produces a solution of sugar in water.
Sodiumchloride is dissociated in water: NaCl-------Na+ + Cl-
Sulphur plus water is a nonhomogeneous mixture.
No it does not. There is no danger with evaporating salt water.
It is a mixture. It is not an element or a compound, so it has to be a mixture. Plus, almost all oils are mixtures, as in if you set them out long enough, they wil separate. This process may take a while, though.
