Answer:
Step-by-step explanation:
To determine the number of moles of Fe2O3 that can be formed by reacting 3.2 moles of iron (Fe), we need to first write and balance the chemical equation for the reaction between iron and oxygen (O2) to form Fe2O3:
4Fe + 3O2 → 2Fe2O3
From the balanced equation, we see that 4 moles of Fe react with 3 moles of O2 to produce 2 moles of Fe2O3. This means that the mole ratio of Fe to Fe2O3 is 4:2, or simply 2:1.
To find the number of moles of Fe2O3 formed from 3.2 moles of Fe, we can use the mole ratio from the balanced equation:
moles of Fe2O3 = 2/4 x 3.2 moles
moles of Fe2O3 = 1.6 moles
Therefore, 1.6 moles of Fe2O3 can be formed by reacting 3.2 moles of iron.
