Calcium carbonate precipitates as a solid, leaving ammonium sulfate in the solution. (NH 4) 2 CO 3 + CaSO 4 → (NH 4) 2 SO 4 + CaCO 3. Ammonium sulfate occurs naturally as the rare mineral mascagnite in volcanic fumaroles and due to coal fires on some dumps. [14] Ammonium sulfate is a byproduct in the production of methyl methacrylate. [15]
Ammonium sulfate is an inorganic salt with a high solubility that disassociates into ammonium (NH + 4) and sulfate (SO 2− 4) in aqueous solutions. [1] Ammonium sulfate is especially useful as a precipitant because it is highly soluble, stabilizes protein structure, has a relatively low density, is readily available, and is relatively inexpensive.

The action of the electron beam is to promote the oxidation of sulfur dioxide to sulfur(VI) compounds. The ammonia reacts with the sulfur compounds thus formed to produce ammonium sulfate, which can be used as a nitrogenous fertilizer. In addition, it can be used to lower the nitrogen oxide content of the flue gas.
Certain types of headaches may be a sign of a more serious condition, such as a brain tumor or aneurysm, especially if the pain is sudden or severe, according to Cohen. "This highlights the ...
The annual per capita consumption of sugar in Sri Lanka is around 30 kg (66 lb) and the total annual requirement of sugar in the country is around 550,000 tons. In 2012, the country only produced 42,940 tons and imported 593,870 tons, [2] with only approximately 7% of the annual requirement produced locally. The balance requirement has to be ...
