Question

The following chemical reaction is balanced, but
the coefficients used are larger than necessary. Rewrite this balanced equation using the smallest coefficients possible.
9Fe(s) + 12H20(I) — 3Fe3O4(s) + 12H2(9)

Answer 1

3Fe(s) + 4H2O(l) — 1Fe3O4(s) + 4H2(g)

Answer 2

Answer:

Explanation:

Divide each coefficient by 3:

3Fe(s) + 4H2O(l) --->  Fe3O4(s) + 4H2(g)
