Answer:
Explanation:
We have iron (iii) oxide been heated in furnaces (where carbon monoxide is the prevalent carbon oxide) to produce carbon dioxide and solid iron
We can write the reaction scheme as follows:
[tex]\begin{gathered} Fe_2O_3\text{ + 3CO }\rightarrow2Fe+3CO_2 \\ \end{gathered}[/tex]
The above is the balanced chemical reaction
Now, we want to sum up the coefficients (these are the numbers before each of the chemical entities in the reaction. For example iron is an entity on its own here)
By doing this, we have 1 +3 + 2 + 3 = 9
The sum of the coefficients is 9
