Web1 jan. 1986 · The graphite-diamond transformation can be achieved directly by subjecting graphite to ultra pressures (>100 kbar) and temperature (>2000 °C). The pressure and temperature at which the conversion takes place can be substantially reduced by using catalyst-solvent materials selected from group VIII of the periodic table and their alloys. Web26 feb. 2024 · The delta H of formation for diamond is actually higher in energy (meaning the product is less stable) than it is for graphite. This means that graphite is more stable, but diamond will not convert back into it because it would require a tremendous amount of energy to overcome the energy barrier to do so.

Web8 jan. 2024 · Yes, it is possible to burn a diamond. However, it requires temperatures that are much hotter than what is found on Earth. Diamonds are made of carbon, and when carbon is exposed to temperatures that are around 4,000 degrees Fahrenheit or higher, it will start to break down and turn into graphite. Web27 dec. 2024 · 1. To acidify the sample, add a few drops of dilute hydrochloric acid (HCl) to the sample. 2. Then, add a few drops of dilute barium chloride (BaCl 2) solution to the sample. 3. If sulfate ions are present in the solution, a white precipitate of barium sulfate (BaSO 4) will form. The reaction is: Ba²⁺ (aq) + SO 4 ²⁻ (aq) → BaSO 4 (s ...
