State whether or not the following equation is balanced: FeO + Al → Fe + Al2O3

If it is not balanced, explain why and provide the balanced equation.

Answer: 3 FeO + 2 Al - > 3 Fe + Al2O3

Explanation:

In order to verify if it is balanced or not you need to count the element at the left and the right. If they arent the same it isnt balanced.

And to balance the equation (simple method, not using redox) you assign coef 1 to the compound with more number of elements Al2O3 in this case and then you complete the rest
