When ammonium carbonate is heated it decomposes to give ammonia gas, carbon dioxide gas and water. The equation for the decomposition is;
(NH4)2CO3(s) = 2 NH3 (g) + CO2(g) + H2O(l)
A glowing splint would extinguish almost immediately because of the presence of carbon dioxide. Carbon dioxide does not support burning which is the property that makes it used a s a fighter extinguisher.

Aluminum carbonate would decompose to produce aluminum oxide and carbon dioxide gas. Carbon dioxide gas will extinguish a glowing splint.

Decomposition of aluminum carbonate

Aluminum carbonate decomposes according to the following equation:

[tex]Al_2(CO_3)_3 ---- > Al_2O_3 + 3 CO_2[/tex]

The gas produced is carbon dioxide. One of the properties of carbon dioxide is that it extinguishes glowing splints. Thus there is no chance that a glowing splint will burn brighter in the presence of the gas.
