Answer 3

It appears you've provided two chemical reactions:

B) HNO3 → H2O + NO2 + O2 This is the decomposition of nitric acid (HNO3) into water (H2O), nitrogen dioxide (NO2), and oxygen (O2). The balanced chemical equation for this reaction is:

4 HNO3 → 2 H2O + 4 NO2 + O2

C) Al + O2 → Al2O3 This is the oxidation of aluminum (Al) by oxygen (O2) to form aluminum oxide (Al2O3). The balanced chemical equation for this reaction is:

4 Al + 3 O2 → 2 Al2O3
