CuSO₄·5H₂O(s) → CuSO₄(s) + 5H₂O(g)
Explanation:
* CuSO₄·5H₂O(s): This represents copper sulfate pentahydrate, a solid compound with five water molecules attached to each copper sulfate molecule.
* CuSO₄(s): This represents anhydrous copper sulfate, a solid compound without any water molecules attached.
* 5H₂O(g): This represents five water molecules in the gaseous state (water vapor).
Key Points:
* The equation is balanced because there are equal numbers of each type of atom on both sides of the equation.
* The "s" after each compound represents its physical state: solid.
* The "g" after the water molecule represents its physical state: gas (water vapor).
This reaction is an example of dehydration where water molecules are removed from a hydrated compound.
