Ammonium carbonate is a chemical compound with the chemical formula [N H 4] 2 C O 3. It is an ammonium salt of carbonic acid. It is composed of ammonium cations [NH 4] + and carbonate anions CO 2− 3. Since ammonium carbonate readily degrades to gaseous ammonia and carbon dioxide upon heating, it is used as a leavening agent and also as ...
Thermal decomposition, or thermolysis, is a chemical decomposition of a substance caused by heat. The decomposition temperature of a substance is the temperature at which the substance chemically decomposes. The reaction is usually endothermic as heat is required to break chemical bonds in the compound undergoing
Gravimetric analysis describes a set of methods used in analytical chemistry for the quantitative determination of an analyte (the ion being analyzed) based on its mass. The principle of this type of analysis is that once an ion's mass has been determined as a unique compound, that known measurement can then be used to determine the same analyte's mass in a mixture, as long as the relative ...
Lipids in the body are mainly contained in adipose tissue, which is made up of about 5-30% water, 2-3% protein, and 60-85% lipids, by weight, of which 90-99% are triglycerides. [3] Adipose tissue is largely composed of neutral lipids, which collectively refers to triglycerides , diglyercides , phospholipids , and cholesterol esters , of which ...
In water solutions, the carbamate anion slowly equilibrates with the ammonium NH + 4 cation and the carbonate CO 2− 3 or bicarbonate HCO − 3 anions: [3] [4] [5] H 2 NCO − 2 + 2 H 2 O ⇌ NH + 4 + HCO − 3 + OH − H 2 NCO − 2 + H 2 O ⇌ NH + 4 + CO 2− 3. Calcium carbamate is soluble in water, whereas calcium carbonate is not.
Europium(III) carbonate can be obtained by mixing and heating an aqueous solution of ammonium carbonate and europium(III) chloride. [2] A saturated carbon dioxide ammonium carbonate solution (obtained from the reaction of hydrochloric acid and ammonium carbonate solution) can also precipitate europium carbonate from a europium salt solution.

Ammonium bicarbonate is an inorganic compound with formula (NH 4)HCO 3. The compound has many names, reflecting its long history. Chemically speaking, it is the bicarbonate salt of the ammonium ion. It is a colourless solid that degrades readily to carbon dioxide, water and ammonia.
It can also be produced by the reaction of barium carbonate with boiling ammonium chlorate solution: [3] 2 NH 4 ClO 3 + BaCO 3 → Ba(ClO 3 ) 2 + 2 NH 3 + H 2 O + CO 2 The reaction initially produces barium chlorate and ammonium carbonate ; boiling the solution decomposes the ammonium carbonate and drives off the resulting ammonia and carbon ...
