Consider the chemical equations shown here. 2Na(s) + Cl2(g) → 2NaCl(s)
4Na(s) + O2(g) → 2Na2O(s)

What is the overall equation for the reaction that produces NaCl and O2 from Na2O and Cl2?

Upper N a subscript 2 upper O (s) plus upper C l subscript 2 (g) right arrow upper N a upper C l (s) plus upper O subscript 2 (g).

2 upper N a subscript 2 upper O (s) plus upper C l subscript 2 (g) right arrow 2 upper N a upper C l (s) plus upper O subscript 2 (g).

2Upper N a subscript 2 upper O (s) plus 2 upper C l subscript 2 (g) right arrow 4 upper N a upper C l (s) plus upper O subscript 2 (g).
