NaCl in water is a mixture.
no and yes
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.
Each crystallic particle is pure NaCl, homogeneous.
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.

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.

NaCl plus CaCO3 plus water
the compound in NaCl, also Sodium Chloride as you said. its commonly known as table salt
o-
Sodiumchloride is dissociated in water: NaCl-------Na+ + Cl-
Sulphur plus water is a nonhomogeneous mixture.
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.
