can you tell if it is a compound or a mixture? Explain.
you cant right? but i dont know how to explain

How do you define a compound or a mixture? It could just be water. Is that a compound or a mixture of Hydrogen and Oxygen?
Or, it could be a simple element such as Nitrogen that's under pressure and therefore not a compound nor a mixture but an element in liquid form.

If it is a clear liquid then it is a homogeneous solution (technically a special case of a mixture) or a pure substance. If the liquid were heterogeneous then the different refractive indexes of the different substances would cause the mixture to be either opaque or translucent, or if the mixture was entirely immiscible then you would see a refractive index dividing line as in the case of oil and water. To further determine if you have a pure substance or a homogeneous mixture I would recommend bringing the solution to a boil and finding out if the substance had a distinct boiling point. If it does have a distinct boiling point then it is a pure substance, if the boiling starts, but the temperature continues to rise as boiling continues then you have a mixture of some sort. (Note that this is barring extraneous potentialities such as superheating the liquid or thermal decomposition products as you are heating the liquid.)
After reading above posts I would also recommend that you not experiment with unknown substances unless you are professionally trained and qualified to do so and have the proper safety measures in place.

Unlabeled Bottled Water

Consider this: tap water is actually a mixture (more specifically a solution aka "homogeneous mixture") of H2O and salts (in chemistry term any ionic compound is a "salt"). Chloride salts are added to water to disinfect, and Fluoride salts are added to water to promote better dental health.
Bottled water is a mixture of H2O and dissolves salts to "add flavor" or nutrition such as magnesium salts, potassium bicarbonate, and fluoride salts.
Tap water and bottled water are profoundly different from "dionized water" (water with no salts dissolved in it), but try comparing the three visually. You'd never be able to tell.
And while tap water is arguably safe to drink, and so is bottled water, drinking DI water would give you a nasty stomach ache.

One cannot. It may be carbon tetrachloride, a water-white compound. It may be a solution of sugar in water. The difference is that you can distil carbon tetrachloride and have it come over as a water-white liquid. If you distil sugar water, you'll get water plus some brown caramel in the boiling flask.

If I found an unlabeled bottle with a clear liquid I would throw it out, you have no idea what is in it and it could be dangerous.

you couldn't tell..
example... if you had water and alcohol in the same bottle you wouldn't be able to tell if it were one or both..
