Aluminum oxide (Al2O3) and iron (Fe) react according to the following
equation:
_Al2O3 + _Fe → _Fe304 +_AL
Balancing the equation requires inserting the correct coefficients to reflect
that no atoms are gained or lost in the reaction. Which is the correct set of
four coefficients, in order?
A. 3, 9, 3,6
B. 4, 9, 3,8
