Thallium carbonate can be used as a catalyst in the high-pressure, high-temperature process of creating artificial diamonds. This process involves subjecting carbon to extreme heat and pressure in the presence of a catalyst, like thallium carbonate, to facilitate the transformation of carbon into diamond crystals. Thallium carbonate helps reduce the activation energy required for diamond formation, allowing for the creation of artificial diamonds in a shorter amount of time compared to natural diamond formation.
The test you are referring to is called a thallium stress test. This test helps evaluate the blood flow to the heart during physical activity by using a radioactive form of thallium injected into the bloodstream. It can help identify areas of reduced blood flow in the heart muscle, indicating possible blockages in the coronary arteries.
To prepare a pure sample of dry carbonate using a solution of ammonium carbonate, you would need to first evaporate the solution to dryness to obtain solid ammonium carbonate. Then, heat the solid in a crucible to decompose it into ammonia, carbon dioxide, and water. Finally, collect the carbon dioxide gas and purify it to obtain the pure dry carbonate.
No, the formula for lithium hydrogen carbonate is LiHCO3. Lithium carbonate has the chemical formula Li2CO3.
When a carbonate reacts with an acid, carbon dioxide gas is released. This reaction often results in the formation of a salt and water as well.
Diamonds are not manufactured; they are mined from the earth's mantle through volcanic activity. However, lab-grown diamonds are artificially created using high pressure and high temperature or chemical vapor deposition techniques to simulate the conditions under which natural diamonds are formed. These lab-grown diamonds have the same physical, chemical, and optical properties as natural diamonds.
By artificial, one must assume that you mean not-natural diamonds, but diamonds formed in a laboratory. The difference is money. Natural diamonds are always more expensive than diamonds formed in a laboratory, given that all the elements about the stone are equal: cut, clarity, carat weight and colour. A certified gemologist will always be able to determine the origin of a diamond.
You can refuse to use diamonds.

Diamonds come from mines, so issues related to mining apply to diamonds, too.
There are those who claim that the Earth's moon is an artificial satellite.

Calcium Carbonate
no
Na2CO3 extract is not used for carbonate test because it is a carbonate compound itself (sodium carbonate). Using it in the test would not provide a valid result, as it would already contain carbonate ions. To test for carbonate ions, a substance that does not already contain carbonate, such as hydrochloric acid, is used.
