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.

Question

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.

DrBob222 · Answer

Fe2O3 + 2Al ==> Al2O3 + 2Fe

B.
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.

C.
Same procedure. Convert mols Fe to mols Al2O3 then convert to grams Al2O3.

@DrBob222 if you could either change your response or let someone else respond that would be great because either you just are incapable of explaining things in a way that would make sense or you are wrong.
