I'm thinking that the gas NH3 is one of the products, but I don't know how to get there. Also, when heated, all of the reactants seem to evaporate, so I'm not sure what the products are.

Possibly NH3 and CO2?

Can somebody please help me with the balancing?

(NH4)2CO3 >> 2 NH3 + H2O + CO2

The usual reason that a chemical reaction happens is that the total energy of a molecule is lower than the total energy of its components. When they react, that energy is released. Most is heat, but some is electromagnetic. But the opposite does happen. The best known example is photosynthesis, the energy 'source' for all of our fossil fuels. In this case, electromagnetic energy is captured to force carbon into molecules with higher energy than their components. Electromagnetic energy, not kinetic energy (heat), dominates. It would take some research to find out whether there are some chemical reactions which are completely heat-neutral. That is, neither endothermic nor exothermic to any degree at all.

You are absolutely right with your propositions, what is left behind is water vapour. If you heat up amonium carbonate, you will end up with vapours of water, carbonic gas and amonia. This is how the thigs got mixed up:

1.- NH3 (g) + H2O (l) = NH4(OH) (aq)

2.- CO2 (g) + H2O (l) = H2CO3

Now, two of (1) plus one of (2)

Gives 2 NH4(OH) + H2CO3 --> (NH4)2CO3 + H2O

Therefore, when you decompose (NH4)2CO3 you will have to give back to Nature its components, NH3, CO2, and water.

Isn´t Nature nice?
