Explanation:
Answer:
Explanation:
Reactants
Solid 'iron'III'oxide' = Fe₂O₃
'carbon'monoxide'gas' = CO
Product
'iron'metal' = Fe
carbon'dioxide'gas = CO₂
Now
Fe₂O₃
+ 3CO
→ 2Fe
+ 3CO₂
The reactants are positioned at the left hand side of the equation.
The products are at the right hand side
s = solids
g = gases
Answer:
