Answer:
43.05 moles of Al needed to react with 28.7 moles of FeO.
Explanation:
Given data:
Moles of FeO = 28.7 mol
Moles of Al needed to react with FeO = ?
Solution:
Chemical equation:
2Al + 3FeO → 3Fe + Al₂O₃
Now we will compare the moles of Al with FeO.
FeO : Al
2 : 3
28.7 : 3/2×28.7 = 43.05 mol
Thus 43.05 moles of Al needed to react with 28.7 moles of FeO.
“Chemical reaction” is the answer
Do you have the molecular weight? I’ve never done this type of chemistry before but from researching it the equation is nxAx100/M. n=# of atoms, A=atomic mass, & M=molecule weight. Sorry if this isn’t helpful, if you can give me an example I may be able to help.
The answer is B. Hope it helps!
