When ammonium carbonate decomposes would a glowing spling burn brighter in the presence of the gases that are evolved?

No. One of the gases produced by burning Ammonium Carbonate is Carbon Dioxide (CO2), so the splint would actually extinquish.

When ammonium carbonate decomposes what would happen to a glowing splint in the presence of the gases that are evoled?
the splint would exstinguish almost imediately
Why iron corroded in the presence of ammonium carbamate?
Ammonium carbamate is a chemical salt resulting from the reaction of ammonia and carbon dioxide. The structure is: H2N-C(=O)-O(-)(+)NH4. Ammonium carbamate can be formed without any intermediates by passing ammonia gas over solid carbon dioxide (dry ice). In the real world, there is often water present and this complicates matters. Carbon dioxide and water can react to form carbonic acid, H2CO3. Carbonic acid is a diprotic acid and can react with 2 equivalents of base, so, when carbonic acid reacts with ammonia, ammonium bicarbonate begins to form; HO-C(=O)-O(-)(+)NH4. As more ammonia is added, ammomium carbonate begins to form; H4N(+)(-)O-C(=O)-O(-)(+)NH4. These are equilibrium reactions. As the concentration of ammonium carbonate increases, there is a conversion of some of the ammonium carbonate to ammonium carbamate. This is a dehydration reaction. An industrially important chemical that is derived from ammonia and carbon dioxide is urea, which is used as fertilizer. Urea is ammonium carbonate that has given up two molecules of water; H2N-C(=O)-NH2. The fertilizer plants that manufacture urea have severe corrosion problems due to the ammonium carbamate intermediate. The corrosion is so severe that carbon steel cannot be used. Some parts of the process will corrode 316 stainless steel. Those heated sections are manufactured from special alloys. Why does iron corrode in the presence of ammonium carbamate? Ammomium carbamate is hygroscopic and will attract moisture. Wetted ammonium carbamate will become an equilibrium mixture of ammonium carbamate and ammonium carbonate. This combination of salts and moisture attacks the protective oxide layer on the surface of steel with chelation-type mechanism. This exposes the underlying base metal for further attack.
What substance forms a precipitate with ammonium oxalate?
I'm in a college chemistry course, C117, and we used ammonium oxalate to test for the presence of Ca^2+.
Is nitride anion or cation?
On its own nitrogen typically forms anions like nitride (N3-) or azide (N3-). However, in the presence of protons (H+), they can also form amide (NH2-) or an ammonium cation (NH4+).
Is marble a mineral?
Marble is composed mainly of the mineral calcite, but because of the presence of other minerals, marble is a rock, not a mineral.

Is ammonium perchlorate a base acid or a base?
Ammonium perhclorate is a salt. It is weakly acidic due to the presence of the ammonium ion.

What are formed from the decomposition of dioxin in the presence of UV B rays?
The ozone decomposes in the presence of UV-B. It has got large energy.
What is the role of ammonium sulfate in test for presence of protein?
The ammonium sulfate denatures the protein, making it available for indicating reagents such as Biuret or Bradford

What does the presence of calcium carbonate indicate?
For example degradation of a pipe by reducing the diameter.
What is colour of an aqueous solution of sodium carbonate in presence of a drop of phenolphthalein?
Pink
Why is chloroform stored in a dark brown bottle?
this is becauseChloroform decomposes when exposed to direct sun light or high temperatures in the absence of air, hence the dark brown bottles. BUT Chloroform also decomposes in a dark place in the presence of air.
Why is sodium carbonate added during extractionin preparation of cyclohexene?
if cyclohexene is prepared by dehydration of cyclohexanol in the presence of a strong acide like H3PO4, sodium carbonate will be used to neutralize the acidic medium
Is sodium hydrogencarbonate a carbonate?
No, it is a bicarbonate. The presence of the extra hydrogen produces a whole range of unique chemical properties.
What is the science behind natural gas?
Natural gas seems to be the result of biological matter that decomposes. Plants especially. It could also be the resulting emanations of petroleum as it decomposes further from it's oily state to a gaseous form notisable in the presence of Propane, Ethane and Methane.
