The reaction between calcium oxide and water produces calcium hydroxide:
CaO (s)+H2O (l)→Ca(OH)2(s) \text{CaO (s)} + \text{H}_2\text{O (l)} \rightarrow \text{Ca(OH)}_2 \text{(s)} CaO (s)+H2O (l)→Ca(OH)2(s)The atom economy for this reaction is 100%.
State how the balanced equation shows that the atom economy is 100%.
