What is graphite' s chemical formula?
Graphite is just an allotrope of the element carbon, in that it is carbon in a different form. Graphite exists in a hexagonal planar structure which allows sheets of graphite to slide over each other easily which is what you see when you write; it is also used as a lubricant (though not in a vacuum) The allotropes of Carbon include diamond, graphite and fullerenes.
The color of a powdered sample of a rock is called the rock's?
The color of a powdered sample of a rock is called its streak. Streak is determined by rubbing the sample across a rough white ceramic plate to reveal the color of the mineral's powder.
What country produces the most in clay and graphite?
China is the largest producer of clay, accounting for a significant portion of the global production. For graphite, China is also a major producer, alongside countries like India and Brazil.
What are the most abundant resources of North Korea?
The most abundant resources of North Korea include coal, iron ore, limestone, magnesite, and graphite. These resources play a significant role in North Korea's economy and industrial production.
How many countries does it take to make a pencil?
It takes multiple countries to make a pencil. For example, the wood may come from one country, the graphite from another, and the metal ferrule may come from yet another country. The components are then assembled in another location before the pencil is distributed globally.
Will graphite leave a clear streak?
Graphite is a mineral that does not leave a clear streak.
Does Graphite leave a clear streak?
i have no idea..... but its probably a no .. take my advice.
What color streak does graphite have?
The same color as the writing from a pencil, very dark grey or black. Pencils used to be made of graphite
How can you tell the difference between graphite and galena?
Graphite is a soft, black mineral that leaves a streak on paper and is used in pencils. Galena is a lead-gray mineral that is heavy and often forms cube-shaped crystals. One way to distinguish them is by conducting a streak test - graphite will leave a black streak, while galena will leave a gray streak.

Which mineral can be esily scratched by a fingernail has cleavage a metallic luster and has a black streak?
The mineral that fits this description is graphite. Graphite is very soft and can be easily scratched by a fingernail. It has a metallic luster and a black streak.
What mineral leaves a streak on paper?
Graphite leaves a streak on paper, as it is the material commonly found in pencils. The black mark left on paper is due to the graphite particles rubbing off onto the surface.
Graphite is a mineral that does not leave a clear streak?
well i really don't know sorry. Here are some useful things close to that... 1. Mica shows clear cleavage. 2. Hardness is a measure of how easily a mineral can be scratched. ill tell you as soon as possible when i figure it out! Thank you
What mineral is soft enough to leave a streak on paper?
The mineral graphite is soft enough to leave a mark on paper. We use graphite, which is a form of carbon, as pencil lead. And it works pretty darn well at leaving marks on paper.
What are ten types of rock that are streak?

What is the streak color does rhodochrosite leave?
White, but i have no idea why or how, it is used in white pencils replacing graphite and is used to write on black paper
What rocks can be identified by the streak test?
The streak test is not a very good identifier of rocks because rocks are composed of combinations of minerals which may have different color streaks. The streak test is mainly used in mineral identification. Even then, it is used in common with other indicators, like hardness, crystal system, and chemical composition.
