What 2 forms of carbon are found in nature?
Diamond and Graphite are the two pure forms of carbon
Which has the less density graphite or diamond?
Graphite is less dense than diamond, due to the differences in crystal structure.
What can graphite be scratched by?
Graphite can be scratched by materials that are harder than it, such as diamond and tungsten.
Graphite is an allotrope of what element?
Diamond, graphite and carbon black are the most common allotropes of CARBON
An element that has two allotropic forms called diamond and graphite?
Carbon has two allotropic forms called diamond and graphite. Diamond is a hard, transparent crystal structure, while graphite is a soft, dark crystal structure known for its lubricating properties.
What are polymorphic minerals?
Polymorphic minerals are two or more minerals that have the same chemical composition, but different crystal structures. For example, pyrite is isometric and marcasite is orthorhombic, but both are composed of iron sulfide. Similarly, diamond and graphite are both composed of carbon, but the former is isometric and the latter is hexagonal.
Why are graphite and diamond considered different minerals?
Diamond and graphite are polymorphic - minerals with the same chemical formula but of different crystal structure. Both are made only of the element carbon. Because they form under different conditions of temperature and pressure, their crystal structure arranged differently. Hence, the vastly different physical properties.Diamonds and graphite are separate allotropes of carbon, different because of their atomic structures. Carbon formed as diamond is the hardest mineral on earth.
The chemical composition of graphite and diamond is?
Graphite and Diamonds are both allotropes of Carbon.
Do both diamond and graphite have a crystal structure?
Yes. Diamond is isometric, graphite is hexagonal.
Which can be used as a lubricant - graphite or diamond?
graphite
What does graphite turn into when put under pressure?
Graphite turns into diamonds when put under extreme pressure and heat. Diamond is a denser and harder form of carbon compared to graphite.
Graphite is more common than diamond?
Yes, graphite is more common than diamond.
What burns hotter diamond or graphite?
diamond
What do diamond graphite and buckminsterfullerene have in common?
Diamond, graphite, and buckminsterfullerene are made of pure carbon and are insoluble in water.
Carbon as graphite can be made into diamonds by putting the graphite under extreme pressure Which of the two materials do you think has the greater density graphite or diamond?
diamond
What 2 forms of carbon are found in nature?
Diamond and Graphite are the two pure forms of carbon
Do diamond and graphite form the same product when burnt?
No, diamond and graphite do not form the same product when burnt. Diamond will convert into carbon dioxide gas, while graphite will also convert into carbon dioxide gas.
