Объяснение:

1. 2Mg + O2 = 2MgO

2.4 Li + 2O2 = 2Li2O

3. 2Ba + O2 = 2BaO

4.2 Zn + O2 = 2ZnO

5. S + O2 = SO2

6.2ZnS + 3O2 = 2ZnO + 2SO2

7.CH4 + 2O2 = CO2 + 2H2O

8.2H2S + 3O2 = 2SO2 + 2H2O

Answer 2

Let's balance these chemical equations:

1. Mg + O2 = MgO (Balanced as it is)

2. 2Li + O2 = 2Li2O

3. 2Ba + O2 = 2BaO

4. 2Zn + O2 = 2ZnO

5. 2S + 3O2 = 2SO3

6. 2ZnS + 3O2 = 2ZnO + 2SO2

7. CH4 + 2O2 = CO2 + 2H2O

8. 2H2S + 3O2 = 2SO2 + 2H2O
