Using the equation, $Fe_2O_3 + 2Al -> 2Fe + Al_2O_3$, how many grams of $Al$ are needed to completely react with 135 grams of $Fe_2O_3$?
The coefficients in the equation provide a molar ratio between the chemical species in the equation, so you must first convert the mass of iron (III) oxide to moles of...

Iron is extracted from iron ore. Part of the process involves reduction of the ore with carbon monoxide. Iron ore contains iron oxide ($Fe_2O_3$). How would you write a balanced equation for the reaction of iron oxide with carbon monoxide?
And this is the effectual chemical reaction of our civilization. If you ever have a chance to tour a blast furnace (and most are in China and India now) do...

How many grams of $Fe_2O_3$ are there in 0.500 mole of $Fe_2O_3$?
Assume that: n = number of moles m = mass of substance M = molar mass (equivalent to atomic weight on the periodic table) $n = m -: M$...

What mass of aluminum is required if 40.0 grams of iron (III) oxide is to be completely consumed in the reaction $Fe_2O_3(s) + 2Al(s) -> 2Fe(l) + Al_2O_3(s)$?
$n_(Fe_2O_3)=m/(m_r)=40/(2xx55.8+3xx16)=0.25mol$. The balanced chemical equation represents ratio in which chemicals combine. Hence 1 mole iron(III)oxide requires 2 moles aluminium. Therefore by ratio and proportion, $0.25 mol$ iron(III)oxide requires $0.50$ moles...

How many moles of iron, $Fe$, can be made from $Fe_2O_3$ by the use of 18 moles of carbon monoxide, $CO$ in the reaction $Fe_2O_3 + CO -> Fe+CO_2$?
The given equation takes the following form when balanced $Fe_2O_3+3CO=2Fe+3CO_2$ This equation reveals that 2moles of Fe is produced when 3moles of CO reacts Hence 18 moles of CO can...

Iron is obtained commercially by the reaction of hematite $Fe_2O_3$ with carbon monoxide. How many grams of iron is produced when 25.0 mol of hematite reacts with 30.0 mol of carbon monoxide?
As can be seen from the chemical equation, each mole of $Fe_2CO_3$ needs 3 moles of $CO$. If 30 moles of $CO$ are used, only 10 moles of $Fe_2CO_3$ can...

If 2.112 g of $Fe_2O_3$ reacts with 0.687 g of $Al$, how much pure $Fe$ will be produced in the reaction $Fe_2O_3(s) + 2Al(s) -> Al_2O_3(s) + 2Fe(s)$?
$"Moles of ferric oxide"=(2.112*g)/(159.69*g*mol^-1)$ $=$ $0.0132*mol$ $"Moles of aluminum"=(0.687*g)/(26.98*g*mol^-1)$ $=$ $0.0254*mol$ Aluminum is in slight deficiency, and is thus the . So $0.0254*molxx55.85*g*mol^-1=1.42*g$. I should add that there is a...

Iron can be extracted from iron(III) oxide by heating it with coke (carbon). The other product in the extraction reaction is carbon dioxide.
What mass of iron is produced by reacting 550g of iron(III) oxide with 60g of coke?
Balanced Equation $"2Fe"_2"O"_3 + "3C"$$rarr$$"4Fe + 3CO"_2$ This is a limiting reactant question. The maximum amount of $"Fe"$ that can be produced is determined by the limiting reactant. We have...

Combining 0.265 mol of $Fe_2O_3$ with excess carbon produced 14.7 g of Fe. $Fe_2O_3 + 3C -> 2Fe +3CO.$ What is the actual yield of iron in moles?
You have the chemical equation, which shows that each mole of ferric oxide should yield 2 moles of iron metal: $Fe_2O_3(s) + 3C(s) rarr 2Fe(l) + 3CO(g)$ $"Moles of iron"$...
