Question

Which of the following equations is balanced? 2Al + 3O2 → Al2O3 N2 + 2H2 → 2NH3 CH4 + 3O2 → CO2 + 2H2O 2Fe2O3 + 3C → 4Fe + 3CO2

Answer 1

the balanced equation is 2Fe2O3 + 3C → 4Fe + 3CO2

Step-by-step explanation:

Answer 2

Answer: the balanced equation is 2Fe2O3 + 3C → 4Fe + 3CO2

Explanation:

• The first equation to be balanced should be 4Al + 3O2 → 2Al2O3.
• The second equation to be balanced should be N2 + 3H2 → 2NH3.
• The third equation to be balanced should be 2CH4 + 4O2 → 2CO2 + 4H2O.
• The fourth choice is balanced and is the right answer.
