Question

General Chemistry

The reaction between aluminum and iron(III) oxide can generate temperatures approaching 3000°C and is used in welding metals:

2 \mathbf{A l}+\mathbf{F e}_{2} \mathbf{O}_{3} \rightarrow \mathbf{A l}_{2} \mathbf{O}_{3}+2 \mathbf{F e}

In one process, 111 g of Al are reacted with 601 g of Fe203. Calculate the mass (in grams) of Al,03formed, and determine the amount of excess reagent left at the end of the reaction.

mass of Al,03 formed:

amount of excess reagent left:
