Can you help me with this problem on enthalpy

Question

For the reaction 4Fe+3O2==>2FeO3 (change in enthalpy=-1652)

 

A. How much heat is released when 4.00 mol iron is reacted with excess O2?

 

B. How much heat is released when 1.00 mol Fe2O3 is produced?

 

C. How much heat is produced when 10.0g Fe and 2.00gO2 are reacted?

 

I already worked out the problem. I just want to check my calculations

Answer 1

If you already worked out the problem, you should show your work so we can see how you approached it and if there are errors we can pin point them, and guide you to the correct answer.  In fact, this question has already been answered by John, I believe.
