Diamond is the hardest mineral known. It is composed of 100% carbon, meaning it cannot 'decompose' in the classic sense where an object's different elements separate from each other.
You can heat a diamond to:
and at that height heat the diamond will melt.
PbSO4 will not decompose upon heating, but it will undergo a phase change from solid to liquid at its melting point of 1170°C.
Heating can decompose mercuric oxide into mercury and oxygen gas.
Sodium carbonate does not decompose on heating because it has a high melting and decomposition temperature. It decomposes at temperatures above 851 degrees Celsius, which is higher than typical heating temperatures in everyday cooking or industrial processes. At lower temperatures, sodium carbonate remains stable.
Heating a Mannich base can lead to decomposition due to the sensitivity of the molecule to heat. The conditions of heating, such as temperature and duration, will affect the extent of decomposition. It is recommended to evaluate the stability of the specific Mannich base in question under the desired heating conditions.
Ammonium salts decompose on heating because they contain ammonium ions (NH4+) which are unstable at high temperatures. When heated, the ammonium ion releases ammonia gas and water vapor as products. This process is known as thermal decomposition.
Aluminum oxide does not readily decompose upon heating. It has a high melting point of around 2,072 degrees Celsius and is a stable compound that does not decompose easily under normal heating conditions.
Yes
PbSO4 will not decompose upon heating, but it will undergo a phase change from solid to liquid at its melting point of 1170°C.
The decomposition temperature depends on the compound. But many organic compounds do decompose on heating.
this is because it does not decompose by heating
Aluminum oxide will not decompose readily upon heating because it is a very stable oxide. Aluminum oxide is passive and is less affected by environmental factors.
Heating can decompose mercuric oxide into mercury and oxygen gas.
Diamonds don't melt.
Metals are not decomposed by heating. Some metals burn, as magnesium.
Sodium carbonate does not decompose on heating because it has a high melting and decomposition temperature. It decomposes at temperatures above 851 degrees Celsius, which is higher than typical heating temperatures in everyday cooking or industrial processes. At lower temperatures, sodium carbonate remains stable.
Nothing is forever, since the universe is finite. But diamonds will last "forever" as far as the human race is concerned. We've only been around for about 100,000 years, and diamonds have been around for billions. Diamonds do in fact decompose spontaneously into graphite, but at a rate so slow that it is unnoticeable even after millions of years.
