The equation shows a reaction involving anhydrous and hydrated copper(II) sulfate:
CuSO4(s)+5H2O(l)⇌CuSO4⋅5H2O(s) \text{CuSO}_4\text{(s)} + 5\text{H}_2\text{O(l)} \rightleftharpoons \text{CuSO}_4 \cdot 5\text{H}_2\text{O(s)} CuSO4(s)+5H2O(l)⇌CuSO4⋅5H2O(s)State what the symbol ⇌ \rightleftharpoons\,⇌ represents in this chemical equation.
