Question

How many moles of carbon monoxide are needed to react completely with 1.75 moles of iron oxide? based on this equation: Fe2O3(s)+3CO(g)--->2Fe(s)+3CO2(g)

Answer 1

Fe2O3(s)+3CO(g)--->2Fe(s)+3CO2(g)
we see that this chemical equation is already balanced. to get the number of moles of CO, we multiply the given moles of Fe2O3 by the stoichiometric ration from the balanced equation,, thu
1.75 mol Fe2O3 * ( 3 mol CO / 1 mol Fe2O3 ) = 5.25 mol CO

hope this helps~ :)

Answer 2

how many moles of o2 are needed to produce 3.91 mol fe2o3

Answer 3

4.56x10-2g Na.
