Write an equation to represent the reaction of gypsum, \(\mathrm{CaSO}_{4} \cdot 2 \mathrm{H}_{2} \mathrm{O},\) with ammonium carbonate to produce ammonium sulfate (a fertilizer), calcium carbonate, and water.

Short Answer

Expert verified
The balanced equation is \( \mathrm{CaSO_4 . 2H_2O} + 2 \mathrm{(NH_4)_2CO_3} → 2 \mathrm{(NH_4)_2SO_4} + \mathrm{CaCO_3} + 2\mathrm{H_2O} \)

Step by step solution

01

Identify the Reactants and Products

The reactants in the equation are given as gypsum (\( \mathrm{CaSO_4.2H_2O} \)) and ammonium carbonate (\( \mathrm{(NH_4)_2CO_3} \)). The products of the equation are given as ammonium sulfate (\( \mathrm{(NH_4)_2SO_4} \)), calcium carbonate (\( \mathrm{CaCO_3} \)), and water (\( \mathrm{H_2O} \)).
02

Write the Unbalanced Equation

Begin by writing an unbalanced chemical equation using the formulae of the reactants and products: \( \mathrm{CaSO_4.2H_2O} + \mathrm{(NH_4)_2CO_3} → \mathrm{(NH_4)_2SO_4} + \mathrm{CaCO_3} + \mathrm{H_2O} \)
03

Balance the Equation

One way to balance the equation is starting with the substances that appear once on each side - in this case, calcium and sulfate ions Ca and SO4. Verify that they are balanced. Next you can move to ammonium and carbonate ions. Both the left and right side of the equation should have two ammonium ions. You can balance this by placing a 2 in front of ammonium carbonate and ammonium sulfate. Lastly, balance the number of water molecules on both sides. The equation becomes: \( \mathrm{CaSO_4 . 2H_2O} + 2 \mathrm{(NH_4)_2CO_3} → 2 \mathrm{(NH_4)_2SO_4} + \mathrm{CaCO_3} + 2\mathrm{H_2O} \)
