Using the following equation: Fe_(2)O_(3)(s)+3H_(2)(g)-2Fe(s)+3H_(2)O(l) How many moles of iron can be made from 6 moles H_(2) 9 moles Fe 6 moles Fe 4 moles Fe 2 moles Fe

To determine how many moles of iron can be made from 6 moles of hydrogen ( ), we need to use the stoichiometric coefficients from the balanced chemical equation: From the equation, we see that 3 moles of produce 2 moles of . Therefore, we can set up a proportion to find out how many moles of are produced from 6 moles of : Solving for : So, 6 moles of can produce 4 moles of . Therefore, the correct answer is:4 moles Fe
