i think diamonds are a compound.
No, diamonds are pure diamond, not a mixture of anything.
Diamonds are formed from pure carbon.
Diamonds are formed from carbon. Any other mineral present is considered an impurity.
No, a diamond is a form of Carbon which is an element.
The best way to clean a diamond is a warm bowl of water and dish soap. Soak the diamonds in that mixture for about five minutes.
Diamonds are formed from carbon. Trace minerals may lend colour.
To separate a mixture of mud water and diamonds, first, allow the mixture to settle. The mud will sink to the bottom, forming a sediment layer. Next, carefully decant the clear water from the top without disturbing the sediment. Finally, use a sieve or filtration method to collect the diamonds from the remaining sediment.
No, diamond is a form of carbon. Other minerals contained in the stone can be considered impurities.
Pure diamond is unique in that it is a gemstone composed of a single element, carbon. However, most white diamonds contain trace amounts of nitrogen, with less than 2% of natural white diamonds having no nitrogen. So, speaking of pure diamond, it is not a mixture, but in reality, most white diamonds do contain trace impurities of nitrogen (less than 1% however).
Coal, pencil lead, and diamonds are all forms of carbon. The difference lies in how the carbon atoms are structured. In coal, carbon atoms are loosely attached, while in diamonds they are tightly bonded, resulting in the hardness of diamonds. Pencil lead is a mixture of graphite (which is a crystalline form of carbon) and clay.
Simple answer: it is a pure substance Non-Simple answer: Diamonds contain impurities in their lattice structure that are other elements, so technically it is slightly a mixture, but only if you get really picky about it.
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.
