Answer:
2 C(s) + O₂(g) + Fe₂O₃(s) + CO(g) → 2 Fe(s) + 3 CO₂(g)
Explanation:
This reaction has 2 steps:
Step 1: 2 C(s) + O₂(g) → 2 CO(g)
Step 2: Fe₂O₃(s) + 3 CO(g) → 2 Fe(s) + 3 CO₂(g)
To get the net chemical equation we need to add both steps, side to side.
2 C(s) + O₂(g) + Fe₂O₃(s) + 3 CO(g) → 2 CO(g) + 2 Fe(s) + 3 CO₂(g)
Then, we have to take out those substances that are repeated on both sides. In this case, we take out 2 moles of CO(g) on each side.
2 C(s) + O₂(g) + Fe₂O₃(s) + CO(g) → 2 Fe(s) + 3 CO₂(g)
This is the net chemical equation and it is balanced.
Answer:
The net chemical equation for the production of iron from carbon, oxygen and iron(III) oxide.
[tex]6C(s)+3O_2(g) +2Fe_2O_3(s)\rightarrow 4Fe(s)+6CO_2(g)[/tex]
Explanation:
Step 1: Carbon and oxygen combines together to form carbon monoxide gas.
[tex]2C(s)+O_2(g)\rightarrow 2CO(g)[/tex]..[1]
Step 2: Carbon monoxide gas formed in previous step is allowed to recat with iron(III) oxide to obtain iron as a product along with carbon dioxide gas
[tex]Fe_2O_3(s)+3CO(g)\rightarrow 2Fe(s)+3CO_2(g)[/tex]..[2]
The net equation of the process can be written by adding both reactions:
3 × [1 ] + 2 × [2]
[tex]6C(s)+3O_2(g) +2Fe_2O_3(s)+6CO(g)\rightarrow 6CO(g)+4Fe(s)+6CO_2(g)[/tex]
Cancelling out common compound son both sides, we get the net chemical equation for the production of iron from carbon, oxygen and iron(III) oxide.
[tex]6C(s)+3O_2(g) +2Fe_2O_3(s)\rightarrow 4Fe(s)+6CO_2(g)[/tex]
