The streak of a mineral is much more accurate in identifying a mineral than color. The streak of a mineral can distinguish minerals with metallic and non-metallic luster. For example, metallic minerals generally have a dark streak whereas non-metallic luster minerals often have a light colored streak.
The mineral with glassy luster, and milky white is Quartz
Quartz
because many minerals are the same color, and some minerals come in many colors

Yes they doAnswer:Some do and some don't - iron pyrites, gold, silver, lead ores - may have a luster. Others like bauxite (aluminum ore), pitchblende (uranium), iron ore are not lusterous.

Sterile water does not contain any minerals. Sterile water contains no germs or micro-organisms. Sterile water is often used for dilution purposes.

Sulfate minerals contain the ion SO42- and generally have a vitreous to dull luster.Sulfide minerals contain the ion S2- and tend to have a metallic luster.Sulfate minerals include the SO42− anion in their chemical makeup, and they are often deposited hydrothermally, by evaporation, or by oxidation of sulfide minerals.Sulfide minerals contain the S2- anion in their chemical makeup. Combining with a wide range of metals like iron, nickel, copper, lead and antimony, the sulfides form an economically important class of metal ores.
Yes. Rocks are defined as combinations of minerals. The only exception to this would be some volcanic rocks that are composed mostly of glass.
Yes. They do.******Contrablue Adds:Unfortunately, this is often incorrect. Many metals are found in chemically "bound" form in their ores -- that is, they are in the form of salts or other compounds rather than the shiny metal. For example, copper is often found in the form of copper carbonate, which is a beautiful green mineral (pure specimens are called "malachite"). But malachite doesn't have a shiny luster because the copper is chemically bonded to oxygen and carbon!The only metals likely to be found "native" or in the uncombined, shiny state, are noble metals such as gold or platinum.The answer is True

They contain delocalised electrons which can move and carry charge.
