Over the years, the thermite reaction (mixing of solid iron (III) oxide with aluminum metal) has been used for welding railroad rails, in incendiary bombs, and to ignite solid-fuel rocket motors.
A. Write a balanced equation representing the reaction.
B. What masses of iron (III) oxide and aluminum must be used to produce 15.0 g if iron?
C. What is the maximum mass of aluminum oxide that could be produced.
Fe2O3 + 2Al ==> Al2O3 + 2Fe
a. mols Fe in 15.0g Fe = grams/molar mass
b. Using the coefficients in the balanced equation, convert mols Fe to mols Fe2O3.
c. Convert mols Fe2O3 to g. g = mols x molar mass
For Al, use the same procedure but in b convert mols Fe to mols Al and go from therre.
Same procedure. Convert mols Fe to mols Al2O3 then convert to grams Al2O3.posted by DrBob222
