The chemical equations are:
PbO2 + 2 H2SO4 + Pb(SO4)2 + 2 H2O
PbO + H2SO4 = PbSO4 + H2O
Sulfur oxides combine with water in the atmosphere to form nitric acid and sulfuric acid through a series of chemical reactions. Water acts as a catalyst in this process, helping the sulfur oxides to react with oxygen and nitrogen compounds present in the air. This reaction is a major contributor to acid rain formation.
A polutted air can contain sulfur oxides (as SO2) which are transformed in sulfuric acid by a reaction with water.
Forming acid rain is a chemical change because it involves the reaction of sulfur dioxide and nitrogen oxides with water, oxygen, and other chemicals in the atmosphere to produce sulfuric acid and nitric acid.
The formation of iron oxides is caused by chemical reaction of iron and oxygen. Note, it is not rusting; rusting also requires the presence of water.
Acid rains contain sulfuric and nitric acids formed from oxides released by autovehicles, fuels burning, some industrial processes.
Oxides are compounds that contain oxygen in combination with one or more other elements. They are formed through a chemical reaction between oxygen and another substance, such as a metal or non-metal. Oxides can be naturally occurring, like rust on iron, or produced synthetically through industrial processes.

Metallic oxides are formed by the reaction of a metal with oxygen and tend to be basic in nature, while non-metallic oxides are formed by the reaction of a non-metal with oxygen and can be acidic, neutral, or basic. Metallic oxides typically conduct electricity, while non-metallic oxides do not.
The reaction between glucose and nitric acid in the presence of sulfuric acid typically leads to the oxidation of glucose, resulting in the formation of gluconic acid or other oxidized products, depending on the reaction conditions. Sulfuric acid acts as a dehydrating agent, facilitating the oxidation process by removing water. This reaction can produce nitrogen oxides as byproducts and may also lead to the formation of carbon dioxide and other organic acids if the oxidation is extensive. Overall, the reaction is characterized by the conversion of glucose into various oxidized organic compounds.
Acid rain is produced when sulfur dioxide and nitrogen oxides in the atmosphere react with water vapor to form sulfuric acid and nitric acid. These pollutants are primarily emitted from the burning of fossil fuels and industrial activities. When rain falls, it carries these acids to the ground, leading to environmental degradation.
Oxides are compounds of oxygen with another chemical element. Salts are the products of the reactions between acids and bases (neutralization reactions).
Combustion of organic materials and fossil fuels produce essentially carbon dioxide, water and some other gases as carbon monoxide, sulfur oxides, nitrogen oxides, etc. Of course the combustion (an oxidation chemical reaction) is an exothermic reaction and produce heat.
