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)
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~ :)
how many moles of o2 are needed to produce 3.91 mol fe2o3
4.56x10-2g Na.
To determine the number of moles of carbon monoxide (CO) needed to react completely with 1.75 moles of iron oxide (Fe2O3), we need to use the balanced chemical equation:
Fe2O3(s) + 3CO(g) → 2Fe(s) + 3CO2(g)
From the balanced equation, we can see that the ratio between Fe2O3 and CO is 1:3. This means that for every 1 mole of Fe2O3, we need 3 moles of CO.
To find the number of moles of CO, we can set up a proportion using the ratios from the balanced equation:
1 mol Fe2O3: 3 mol CO = 1.75 mol Fe2O3: x mol CO
The proportion can be written as:
1/3 = 1.75/x
To solve for x, we can cross-multiply:
1 * x = 3 * 1.75
x = (3 * 1.75)/1
x = 5.25
Therefore, 5.25 moles of carbon monoxide are needed to react completely with 1.75 moles of iron oxide.
