No. Diamonds are pure carbon. Coal is not; it contains all sorts of hydrocarbon molecules. The high-pressure, high-temperature processes for making synthetic diamonds start with pure carbon. The chemical vapor deposition process uses a very specific mixture of gases.

Diamonds and graphite are examples of what solid?

Diamonds and graphite are both allotropes of carbon.


What element makes diamonds valuable?

The value of diamonds is based on their rarity, durability, and beauty. Diamonds are composed of carbon atoms arranged in a unique crystal structure that gives them their distinct properties, making them highly sought after for use in jewelry and industrial applications.


What are two mineral characteristics that differ between herkimer diamonds and true diamonds?

Herkimer diamonds are double-terminated quartz crystals found in Herkimer County, New York, while true diamonds are carbon-based minerals. Herkimer diamonds have a lower hardness rating (7.5) compared to true diamonds (10). Additionally, herkimer diamonds are typically clear or smoky in color, whereas true diamonds exhibit a range of colors depending on impurities.


What is the difference in properties between diamonds and graphite, and how does the presence of carbon affect their structures and characteristics?

Diamonds and graphite are both forms of carbon, but they have different properties due to their structures. Diamonds have a rigid, three-dimensional structure with strong covalent bonds, making them hard and transparent. Graphite, on the other hand, has layers of carbon atoms arranged in sheets with weak forces between the layers, making it soft and opaque. The presence of carbon in both substances gives them unique characteristics based on their structures, such as hardness and conductivity.


How many karats is pure diamonds?

Karats is a purity measurement for gold; carats is a weight measurement for diamonds. All diamonds are pure diamond. Gold, however, comes in a range of karats, from 9, 10, 14, 18, 22 and 24, which is pure gold.

What is a diamonds formula?

Most diamonds are made entirely out of tightly compressed carbon in a triangle pattern.Another AnswerAll diamonds are formed from carbon -- C on the periodic table. Their atomic structure is Isometric-Hexoctahedral or cubic. This structure is based in fours or eights, not threes.


Will a diamond break down?

Diamonds are actually the strongest material, but you can also break it by burning it. Try it and you will see that a hard diamond has turned into many shattered pieces. If you rub it other diamonds, it will only make a little scratch!


Why do chemists classify CHCl3 as an organic substance even though the substance is not produced by organisms?

Because it's a carbon based compound.
