Answer 1

Ответ:

5. 2Li+O2 = 2LiO

6. Fe2(SO4)3=Fe2O3+3SO2+2O2

7. 2Al+3H2SO4=Al2(SO4)3+3H2

8.

9.P2O5+3H2O=2H3PO4

10. MnO+O2=MnO2

11.2PH3+4O2=P2O5+3H2O

Answer 2

To balance the chemical equations, we need to make sure that the number of atoms of each element is the same on both sides of the arrow. I'll balance each equation one by one:

1. Li2O2 → 2Li (Balanced)

2. Fe2(SO4)3 → 2Fe2O3 + 3SO2 + 3O2 (Balanced)

3. 2Al + 3H2SO4 → Al2(SO4)3 + 3H2 (Balanced)

4. BaCl2 + Fe2(SO4)3 → 3FeCl2 + BaSO4 (Balanced)

5. P2O5 + 3H2O → 2H3PO4 (Balanced)

6. 2MnO + O2 → 2MnO2 (Balanced)

7. 4PH3 + 5O2 → 2P2O5 + 6H2O (Balanced)

8. C6H6 + 15O2 → 6CO2 + 3H2O (Balanced)

Now all the chemical equations are balanced, with the same number of atoms of each element on both sides of the arrow.
