blast furnaces extract pure iron from the iron(iii) oxide in iron ore in a two step sequence. in the first step, carbon and oxygen react to form carbon monoxide:\n2c(s) + o₂(g) → 2co(g)\nin the second step, iron(iii) oxide and carbon monoxide react to form iron and carbon dioxide:\nfe₂o₃(s) + 3co(g) → 2fe(s) + 3co₂(g)\nwrite the net chemical equation for the production of iron from carbon, oxygen and iron(iii) oxide. be sure your equation is balanced.
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))
