When solid ammonium carbonate is heated, it decomposes to form ammonia gas, carbon dioxide gas, and water vapor, so that the solid completely disappears. Write a complete, balanced equation for this reaction.

(NH4) 2CO3 (s) → 2 NH3 (g) + CO2 (g) + H2O (g)

Explanation:

The balanced equation can be written when we know the chemical formula of each reactants and products of the reaction.

Ammonium carbonate = (NH4) 2CO3 (s)

Ammonia = NH3 (g)

carbondioxide = CO2 (g)

water = H2O (g)

The ammonium carbonate was decomposed in the reaction, so,

(NH4) 2CO3 (s) → NH3 (g) + CO2 (g) + H2O (g)

The reactant is on the left side while the product is on the right side. Let us balance the equation to make sure every atom of element is same number on both sides of the equation.

(NH4) 2CO3 (s) → 2 NH3 (g) + CO2 (g) + H2O (g)
