Write the equations of chemical reactions: 1) C -CO2- H2CO3 2) S- SO2- SO3- H2SO4

1 chain:

1) C + O2 = CO2 (when carbon interacts with oxygen, carbon monoxide (IV) is formed);

2) CO2 + H2O = H2CO3 (when carbon (IV) oxide interacts with water, carbonic acid is formed).

2 chain:

1) S + O2 = SO2 (when sulfur reacts with oxygen, sulfur (IV) oxide is formed);

2) SO2 + O3 = SO3 + O2 (when sulfur (IV) oxide interacts with ozone, sulfur (VI) oxide and oxygen are formed);

3) SO3 + H2O = H2SO4 (when sulfur (VI) oxide reacts with water, sulfuric acid is formed).
