Answer

Explanation:

Step1: Combine the two reactions

First reaction: (2C(s)+O_{2}(g)\rightarrow 2CO(g)) Second reaction: (Fe_{2}O_{3}(s)+3CO(g)\rightarrow 2Fe(s)+3CO_{2}(g))

To get the net reaction, we need to make sure the (CO) cancels out. Multiply the first reaction by (3) and the second reaction by (2).

First reaction after multiplication: (6C(s)+3O_{2}(g)\rightarrow 6CO(g)) Second reaction after multiplication: (2Fe_{2}O_{3}(s)+6CO(g)\rightarrow 4Fe(s)+6CO_{2}(g))

Step2: Add the two multiplied reactions

Add the left - hand sides: (6C(s)+3O_{2}(g)+2Fe_{2}O_{3}(s)+6CO(g)) Add the right - hand sides: (6CO(g)+4Fe(s)+6CO_{2}(g))

Cancel out the (6CO(g)) on both sides.

Answer:

(6C(s)+3O_{2}(g)+2Fe_{2}O_{3}(s)\rightarrow 4Fe(s)+6CO_{2}(g))
