13. Iron is produced from its ore by the reactions:\(2\text{C(s)} + \text{O}_2\text{(g)} \to 2\text{CO(g)}\)\(\text{Fe}_2\text{O}_3\text{(s)} + 3\text{CO(g)} \to 2\text{Fe(s)} + 3\text{CO}_2\text{(g)}\)How many moles of \(\text{O}_2\)(g) are needed to produce 1 mole of Fe(s)?(A)0.5 mole \(\text{O}_2\)(B)0.75 mole \(\text{O}_2\)(C)1 mole \(\text{O}_2\)(D)1.5 mole \(\text{O}_2\)
