Question

__Fe + __O2 to__Fe2 03
A.4, 1, 2
B.2, 3, 2
C.2, 1, 2
D.4, 3, 2

Answer 1

The correct answer is A. 4, 1, 2.

In the balanced chemical equation for the reaction between iron (Fe) and oxygen (O2) to form iron(III) oxide (Fe2O3), the coefficients are as follows:

Fe + O2 -> Fe2O3

4Fe + 3O2 -> 2Fe2O3
