Answer:
To determine the mole ratio of Fe to O in the context of a chemical equation, we typically refer to the coefficients of Fe and O in the balanced equation.
Let's consider a hypothetical balanced equation:
Fe
2
O
3
→
2
Fe
+
3
O
2
Fe
2
O
3
→2Fe+3O
2
In this balanced equation:
The coefficient of Fe (iron) is 2.
The coefficient of O (oxygen) is 3.
Therefore, the mole ratio of Fe to O in this equation is
2
:
3
2:3.
So, among the options provided:
1:3
1:4
3:1
4:3
The correct mole ratio of Fe to O is
2
:
3
2:3
.
