Explain why color is not a good test for distinguishing between pyrite and gold?
Since pyrite (a.k.a. fool's gold) and gold have the same color, it can be very difficult to distinguish between them. A very accurate way to distinguish them is by streaks.
Explain why the color is not good test for distinguishing betweenpyrite and gold?
Both have the same color and metallic luster. Pyrite is called "fool's gold" for that reason.
Explain why color is not a good test dor distinguishing between pyrite and gold what test is most reliable dor identifying these two minerals?
Because they look alike
Describe why color and streak are useful in identifying pyrite?
Pyrite's color is extremely similar to that of gold. However, the streak of pyrite is black. This can be used to distinguish it from gold.
What color is the streak of a pyrite?
the color of crushed pyrite is a greenish brown. Compared to gold which is gold.
What mineral property can be used to distinguish between pyrite and chalco pyrite?
Pyrite also known as "fool's gold" is a mineral that has both a different chemical, morphological and physical characteristics than gold. Gold is denser (i.e. the same size of gold is much heavier than the that of pyrite). Gold's average density is 17.64 g/cm3 while Pyrite's density is on average 5.01 g/cm3. The chemical formulas are different. Gold's chemical formula is "Au" while Pyrite's is and iron sulfate mineral with a formula of "FeS2". The color is also different, gold appears the color of gold while pyrite is more bronze in color. The crystallographic form of the minerals also vary. Gold is a very soft mineral while Pyrite is much harder (gold has a hardness of 2.5 while Pyrite is 6.5). To distinguish between a sample of each, you could scratch the surface of gold using your fingernail which you would not be able to do with pyrite. You can try to scratch it because pyrite or fools gold much harder then gold so if it doesn't scratch that much it is most likely pyrite or fools gold. You can tell them apart by looking at their reflection and streak. Also, gold is much more dense than pyrite, so the same volume would 'weigh' about 3.5 times more. Gold has a hardness of about 2.5, while pyrite is about 6 (Gold is softer and more malable). Streak is used to distinguish between Gold and Pyrite.
How Color of the same is all that is needed to distinguish between real gold and fool 's gold?
The color of pyrite and gold are different in the powdered state achieved by rubbing an edge of the mineral against an unglazed tile. This color is called the mineral's streak. Gold will have a shiny gold streak and pyrite will have a blackish green streak.
What colors does pyrite come in?
Pyrite ranges in color from dull and brassy to shiny yellow-gold.
What mineral has the color of gold?
I think you are referring to Pyrite, also called "Fool's Gold". Pyrite is actually Irondisulfide: FeS2
Is pyrite black?
No, pyrite is a golden yellow cubic crystal. This color is why it is commonly called "fools gold".
What mineral is sometimes confused with gold?
Iron Oxide. Pyrite is known also as "Fool's Gold"
How streak is used to distinguish between gold and pyrite?
Gold will have a yellow metallic streak, pyrite will have a greenish-black streak.
