Industrial ethanol is synthesized via the catalytic hydration of ethene:
C2H4(g)+H2O(g)→C2H5OH(g) \text{C}_2\text{H}_4\text{(g)} + \text{H}_2\text{O(g)} \rightarrow \text{C}_2\text{H}_5\text{OH(g)} C2H4(g)+H2O(g)→C2H5OH(g)Explain how this balanced chemical equation shows that the reaction has an atom economy of 100%.
