Right Debendra, let's go. Here are the balanced chemical equations for Part B: 1. Fe + H_2O → Fe_3O_4 + H_2 Step 1: Balance Fe atoms. 3Fe + H_2O → Fe_3O_4 + H_2 Step 2: Balance O atoms. 3Fe + 4H_2O → Fe_3O_4 + H_2 Step 3: Balance H atoms. 3Fe + 4H_2O → Fe_3O_4 + 4H_2 2. Al + O_2 → Al_2O_3 Step 1: Balance Al atoms. 2Al + O_2 → Al_2O_3 Step 2: Balance O atoms by finding the least common multiple (LCM) of 2 and 3, which is 6. 4Al + 3O_2 → 2Al_2O_3 Step 3: Re-balance Al atoms. 4Al + 3O_2 → 2Al_2O_3 3. KClO_3 → KCl + O_2 Step 1: Balance O atoms by finding the LCM of 3 and 2, which is 6. 2KClO_3 → KCl + 3O_2 Step 2: Balance K and Cl atoms. 2KClO_3 → 2KCl + 3O_2 4. Na + H_2O → NaOH + H_2 Step 1: Balance H atoms by making the number of H atoms on the right side even. Na + H_2O → 2NaOH + H_2 Step 2: Balance H atoms on the left. Na + 2H_2O → 2NaOH + H_2 Step 3: Balance Na atoms. 2Na + 2H_2O → 2NaOH + H_2 5. BaCl_2 + Na_2SO_4 → BaSO_4 + NaCl Step 1: Balance Cl atoms. BaCl_2 + Na_2SO_4 → BaSO_4 + 2NaCl 6. Zn + HCl → ZnCl_2 + H_2 Step 1: Balance Cl atoms. Zn + 2HCl → ZnCl_2 + H_2 7. Ca(OH)_2 + CO_2 → CaCO_3 + H_2O Step 1: Check atom count. All atoms are already balanced. Ca(OH)_2 + CO_2 → CaCO_3 + H_2O 8. Pb(NO_3)_2 → PbO + NO_2 + O_2 Step 1: Balance N atoms. Pb(NO_3)_2 → PbO + 2NO_2 + O_2 Step 2: To balance O atoms, multiply Pb(NO_3)_2 by 2. 2Pb(NO_3)_2 → PbO + 2NO_2 + O_2 Step 3: Balance Pb atoms. 2Pb(NO_3)_2 → 2PbO + 2NO_2 + O_2 Step 4: Re-balance N atoms. 2Pb(NO_3)_2 → 2PbO + 4NO_2 + O_2 What's next?
