Question

If a chemical reaction such as the formation of our own oxide contains for Adams of iron(Fe) in the product how many items of iron would be the reactants?

a. 12
b. 8
c. 4
d. 2

Answer 1

The reaction to form Fe2O3 requires 2 atoms of iron as reactants.

Step-by-step explanation:

The question is asking how many atoms of iron are needed as reactants in a chemical reaction that produces iron(III) oxide (Fe2O3) as the product. The balanced chemical reaction for the formation of Fe2O3 is:

2 Fe(s) + 3/2 O2(g) → Fe2O3(s)

From this balanced equation, we can see that 2 atoms of iron (Fe) are needed as reactants to produce 1 molecule of Fe2O3. Therefore, the answer is d. 2.
