Question

Balance the following reactions ? A. Al + O2 → Al2O3 B. FeSO4 → Fe2O3+ SO2 + SO3​

Answer 1

Answer:

A --- 4 Al + 3 O2 → 2 Al2O3

• 4 Aluminium on each side and 6 oxygen on each side makes this reaction balanced

B--- 2 FeSO4 → Fe2O3+ SO2 + SO3​

• The atoms are equal on both sides, making this reaction balanced.
