Question

Al+O2= Fe+___=Fe3O4 H2O+___=LiON Co2+___=CaCO3 Fe(OH)3=Fe2O3+___ P2O5+______=H3PO4

Answer 1

1.4Al+3O2=2Al2O3

2.4Fe+3O2=2Fe2O3

3.2H2O+2Li=2LiOH+H2

Answer 2

To balance the chemical equations you provided, I'll fill in the missing elements and coefficients:

1. Al + O2 = Al2O3 (2 Al + 3 O2 = 2 Al2O3)

2. Fe + O2 = Fe2O3 (4 Fe + 3 O2 = 2 Fe2O3)

3. H2O + LiNO3 = LiOH + HNO3 (H2O + 2 LiNO3 = 2 LiOH + HNO3)

4. Co2+ H2O + CO2 = CaCO3 (CaCO3 + H2O = CaCO3 + CO2)

5. Fe(OH)3 = Fe2O3 + H2O (2 Fe(OH)3 = Fe2O3 + 3 H2O)

6. P2O5 + 3 H2O = 2 H3PO4 (P2O5 + 3 H2O = 2 H3PO4)

Please note that these balanced equations may not represent real-world reactions but have been balanced based on the given information. If you encounter any chemical reactions in a practical setting, always double-check and verify the balanced equations.
