Question

S- HgS-SO2-SO3-H2SO4

Answer 1

Ответ:

Объяснение:

Hg + S = HgS

2HgS + 3O2 = 2SO2 + 2HgO

2SO2 + O2 =2SO3

SO3 + H2O = H2SO4

Answer 2

The given sequence represents the chemical reactions and transformations of mercury (Hg) sulfide (HgS) into sulfur dioxide (SO2), sulfur trioxide (SO3), and finally into sulfuric acid (H2SO4). Let's break down each step:

1. HgS (Mercury Sulfide): HgS is the chemical formula for mercury (II) sulfide, commonly known as cinnabar. It is a naturally occurring mineral form of mercury.

2. HgS + O2 -> Hg + SO2 (Sulfur Dioxide): In this step, mercury sulfide (HgS) reacts with oxygen (O2) to produce elemental mercury (Hg) and sulfur dioxide (SO2) gas.

3. 2 SO2 + O2 -> 2 SO3 (Sulfur Trioxide): Sulfur dioxide (SO2) further reacts with oxygen (O2) to form sulfur trioxide (SO3).

4. SO3 + H2O -> H2SO4 (Sulfuric Acid): Sulfur trioxide (SO3) reacts with water (H2O) to form sulfuric acid (H2SO4).

Overall, the complete reaction sequence can be represented as:

HgS + 3 O2 + H2O -> Hg + 2 SO2 + H2SO4

It's essential to note that these reactions are not just a single continuous process, but a series of individual chemical reactions that describe the conversion of mercury sulfide into sulfuric acid via intermediate steps. The reactions may require specific conditions such as temperature, pressure, and catalysts to proceed effectively.
