Answer:
3C + 2Fe ₂ O ₃ → 3CO ₂ + 4Fe
Explanation:
C + Fe ₂ O ₃ → CO ₂ + Fe
Left Side
C = 1
Fe = 2
O = 3
Right Side
C = 1
Fe = 1
O = 2
So we can see that while Carbon is balanced Fe and O are not.
We then attempt to balance the equation by balancing the Oxygen.
C + 2Fe ₂ O ₃ → 3CO ₂ + Fe
Left Side
C = 1
Fe = 4
O = 6
Right Side
C = 3
Fe = 1
O = 6
Oxygen is now balanced but C and Fe are not, though this is an easy fix as each are independent on each side of the equation.
3C + 2Fe ₂ O ₃ → 3CO ₂ + 4Fe
Left Side
C = 3
Fe = 4
O = 6
Right Side
C = 3
Fe = 4
O = 6
