What else can I help you with?
If you obtain the powder of a mineral by rubbing the mineral on a porcelain which property have you observed?
By rubbing a mineral on porcelain to obtain powder, you are observing its streak. The streak is the color of the powder produced when the mineral is scraped across a hard, unglazed surface, such as porcelain. This property helps in identifying the mineral, as the streak color can be different from the mineral's external color.
Would a mineral of a hardness of 9 leave a streak Why or why not?
A mineral with a hardness of 9, such as corundum, would not leave a streak on a streak plate because it is harder than the plate itself, which typically has a hardness of about 6. A harder mineral cannot scratch a softer material, so it wouldn't produce a streak. Streak is determined by the powder left behind when a mineral is scraped against a harder surface, and since the mineral is too hard, it cannot do so.
What would you observe in a streak test?
In a streak test, you would observe the color of the powdered mineral after it has been scraped against a porcelain plate. The color of the streak left behind can sometimes be different from the color of the mineral itself, which can be helpful in identifying the mineral.
What is the streak of tanzanite?
Tanzanite has a streak that is typically a light blue to violet color. Streak refers to the color of the powder produced when a mineral is scraped across a hard surface, such as a porcelain plate. This characteristic can be useful in identifying the mineral, as the streak color may differ from the color of the mineral itself. Tanzanite's streak helps to confirm its identity in mineralogy.
What are luster and streak?
Luster refers to how a mineral's surface reflects light - it can be metallic, glassy, pearly, or dull. Streak is the color of a mineral's powder when rubbed against an unglazed tile and can help identify the mineral even if its external color is different.
A rock leaves a white streak when it is scraped across a surface it probably contains what mineral that is used to make powder?
The rock likely contains the mineral talc, which is known for leaving a white streak when scratched against a surface. Talc is commonly used in the production of powder products such as baby powder and cosmetics.
The color of a minerals powder is its what?
The color of a mineral's powder is its streak. This is the color of the powdered form of the mineral when it is scraped against a hard surface. Streak is a more reliable indicator of a mineral's identity than its exterior color.
If you obtain the powder of a mineral by rubbing the mineral on a porcelain which property have you observed?

This property helps in identifying the mineral, as the streak color can be different from the mineral's external color.
How are streak and luster alike?
Both streak and luster are properties used to identify minerals. Streak is the color of the powder left behind when a mineral is scraped against a harder surface, while luster describes how light is reflected off the surface of a mineral. Both properties can provide clues about the identity and composition of a mineral.
What refers to the colored powder resulting from rubbing a mineral against a harder surface?
streak
Does A minerals ability to reflect light refer to streak?
No, a mineral's ability to reflect light does not refer to streak. Streak is the color of the powder left by a mineral when it is scraped across a rough surface. The ability of a mineral to reflect light is usually related to its luster, which describes how light interacts with the mineral's surface.
What is the color of the powder that a mineral leaves went is scratched across a special plate?
The color of the powder left by a mineral when scratched across a special plate is called the streak color. This color may differ from the actual color of the mineral itself and is a helpful characteristic in mineral identification.
Would a mineral of a hardness of 9 leave a streak Why or why not?

Streak is determined by the powder left behind when a mineral is scraped against a harder surface, and since the mineral is too hard, it cannot do so.
Which mineral property is identified by the color of the powder left behind when it is rubbed across a surface?
The mineral property identified by the color of the powder left behind when a mineral is rubbed across a surface is called the mineral's streak.
What would you observe in a streak test?
In a streak test, you would observe the color of the powdered mineral after it has been scraped against a porcelain plate. The color of the streak left behind can sometimes be different from the color of the mineral itself, which can be helpful in identifying the mineral.
What mineral test leaves a line of powder on a plate?
The streak test is used to determine the color of the powder left behind when a mineral is scraped along a white ceramic plate. This color is often different from the color of the mineral itself and can help identify the mineral.
What color is left behind a mineral when rubbed against black or white tile?
A streak test can be used to identify a mineral's color by rubbing it against an unglazed porcelain tile to observe the color of the powder left behind. This color may differ from the mineral's surface color.
