Oh sorry I forgot the arrows!

Question

Over the years, the thermite reaction has been used for welding railroad rails, in incendiary bombs, and to ignite solid-fuel rocket motors. The reaction is given below.

Fe2O3(s) + 2 Al(s) -->2 Fe(l) + Al2O3(s)

What masses of iron(III) oxide and aluminum must be used to produce 30.0 g iron? What is the maximum mass of aluminum oxide that could be produced?

Answer 1

1. Convert 30 g Fe to moles. moles = grams/molar mass.
2. Using the coefficients in the balanced equation, convert moles Fe to moles Fe2O3.
3. Now convert moles Fe2O3 to grams. g = moles x molar mass.

4. Same process to determine g Al needed.
Post your work if you get stuck.

Answer 2

Ohh okay THANK YOU so much drbob222!

Answer 3

NFe2O3/1=0.26/2?
