The name of hard carbon is Diamond. If you are speaking of coal then it would anthracite. Carbon has another allotropic form which is graphite.
Carbon dioxide is a colorless gas at room temperature and pressure. It is not hard in the traditional sense of the word.
No, carbon in its pure form is not typically shiny. It can appear as a dull black or grey color in its natural state. However, certain forms of carbon, such as synthetic diamonds, can be cut and polished to create a shiny appearance.
Carbon itself does not have a distinct feel as it is typically found in solid form such as graphite or diamonds. Graphite feels slippery or powdery due to its layer structure, while diamonds feel hard and smooth due to their crystal structure. Carbon in other forms, such as carbon fibers or carbon nanotubes, may feel like a lightweight, strong material.
At standard temperature and pressure (STP), carbon exists in the solid state as graphite or diamond. Graphite is a soft, black material with a layered structure, while diamond is a hard, clear crystal made of carbon atoms arranged in a tetrahedral lattice.
When carbon and silicon are put together, they can form silicon carbide (SiC), commonly known as carborundum. Silicon carbide is a hard and abrasive material used in various industries for making cutting tools, grinding wheels, and abrasive powders.
The hardness or softness depends on which state the carbon is in. Carbon can be found in coal and graphite (which isn't very hard) , but it can also be found in diamonds......which are.....hard.
state how low carbon steels can be given a hard case?
Carbon dioxide is a colorless gas at room temperature and pressure. It is not hard in the traditional sense of the word.
Diamond is a very hard native crystalline carbon valued as a gem
While carbon can be very hard, it is not necessarily brittle. The properties of carbon can vary depending on its structure and form. For example, diamond is a form of carbon that is both extremely hard and strong, while graphite is another form of carbon that is soft and brittle.
High carbon steels are hard, strong and resistant to wear.
hard and brittle so YES
hard and brittle so YES
Carbon can bend to a point. It holds up pretty well but its not meant to bent hard.
Diamond is the Hardest in the world. Coming from carbon. Iron, Gold , Aluminium are hard metals
Compounds can be classified as organic( containing carbon) or inorganic( not containing carbon).
Anthracite coal has the highest carbon content among all types of coal. It is a hard, shiny, and dense coal that is often referred to as "hard coal."
