Old iron objects from tombs in Britain are often covered with rust. Iron reacts with oxygen when it rusts What else is needed for iron to go rusty?
Rusting is an oxidation reaction. The iron reacts with water and oxygen to form hydrated iron(III) oxide, which we see as rust. Iron and steel rust when they come into...

Iron (III) oxide reacts with carbon to give iron and carbon monoxide.
Fe2O3 (s) + 3C(s) ….. 2Fe (s) + 3CO(s)
How many grams of Fe can be produced when 6.00 g of Fe2O3 reacts?
Fe2O3M = 159,692Fe2M = 2*55.85 = 111.17 m (Fe) = 111.17*6.00/159,69 = 4,197 g - produced!

1. Given: 2Al(s) + Fe2O3(s) à Al2O3(s) + 2Fe(l) Step 1 is done!
How many grams of Fe2O3 are needed to produce 6.7 g of Fe?
Step 2: Mass to moles
Step 3: Mole to Mole (Ratio)
Step 4: Mole to Mass
2Al(s) + Fe2O3(s) = Al2O3(s) + 2Fe(l)n=m/MM (Fe) = 55.9 g/molM (Fe2O3) = 159.7 g/moln (Fe)=6.7/55.9 = 0.12 moln (Fe2O3) = 1/2 x n (Fe) = 1/2 x 0.12 =...

6Na + Fe2O3 --> 3Na2O + 2Fe If you are provided 200g of sodium and 250 grams of iron(III) oxide, which substance is the limiting reactant? Explain your reasoning.
6Na + Fe2O3 → 3Na2O + 2Fe n(Na) = m/M = 200g/23g/mol = 8.7 moles n(Fe2O3) = 250g/160g/mol = 1.6 moles The limiting reactant in a chemical reaction is the...
