Question

D H2 (So2)-? D Воздуха (So2)2-?

Answer 1

D(so2 за h2)=64/2=2
D((so2)2 за воздухом)=128/29=4.41

Answer 2

It seems like you are asking about the reactions involving sulfur dioxide (SO2) in water and air. Let's break it down:

1. Dissolution of SO2 in water: When sulfur dioxide (SO2) dissolves in water (H2O), it forms sulfurous acid (H2SO3). The reaction can be represented as follows:

SO2(g) + H2O(l) -> H2SO3(aq)

2. Formation of sulfite ion in aqueous solution: Sulfurous acid (H2SO3) further dissociates in water to form sulfite ions (SO3^2-) and hydronium ions (H3O+):

H2SO3(aq) + H2O(l) -> HSO3^-(aq) + H3O+(aq)

3. Reaction with another SO2 molecule in air: In the presence of air (which contains oxygen), two molecules of SO2 can react with each other to form sulfur trioxide (SO3):

2SO2(g) + O2(g) -> 2SO3(g)

4. Formation of sulfite ion from SO3 in air: Sulfur trioxide (SO3) can react with water vapor (H2O) in the air to form sulfuric acid (H2SO4). The sulfuric acid can then dissociate to produce sulfate ions (SO4^2-) and hydronium ions (H3O+):

SO3(g) + H2O(g) -> H2SO4(aq) H2SO4(aq) -> HSO4^-(aq) + H3O+(aq) HSO4^-(aq) -> SO4^2-(aq) + H2O(l)

It is important to note that sulfur dioxide (SO2) is a significant air pollutant that can lead to the formation of acid rain when it reacts with water and oxygen in the atmosphere. Acid rain can have harmful effects on the environment, including damage to plants, aquatic life, and buildings. Efforts to reduce emissions of SO2 and other pollutants are crucial to mitigate the negative impacts on the environment and human health.
