Over the years, the thermite reaction has been used for welding railroad ralls, in incendiary bombs; and to ignite sobid fuel rocket motors. The reaction is \[ \mathrm{Fe}_{2} \mathrm{O}_{3}(s)+2 \mathrm{Al}(s) \rightarrow 2 \mathrm{Fe}(l)+\mathrm{Al}_{2} \mathrm{O}_{3}(s) \] a. What mass of iron(II) oxide must be used to produce \( 18.6 .9 \) Iron? \[ \text { Mass = } 9 \] b. What mass of aluminum must be used to produce \( 18.6 \mathrm{~g} \) iron? \[ \text { Mass = } 9 \] c. What is the maximum mass of aluminum oxide that could be produced? \[ \text { Mass = } 9 \]
