Question

S->SO2->K2SO3->MgSO3

Answer 1

Ответ:

Объяснение:

S + O2 = SO2

SO2 + 2KOH = K2SO3 + H2O

K2SO3 + MgCl2 = MgSO3 + 2KCl

Answer 2

The given sequence represents a series of chemical reactions starting with S and ending with MgSO3. Let's break it down step by step:

1. S: This likely represents an element, sulfur (S) in its elemental form.

2. SO2: Sulfur dioxide (SO2) is a compound formed when sulfur (S) combines with oxygen (O). It is a colorless gas with a pungent odor, commonly released during the combustion of fossil fuels.

3. K2SO3: Potassium sulfite (K2SO3) is a compound formed when sulfur dioxide (SO2) reacts with potassium hydroxide (KOH) or potassium oxide (K2O). Potassium sulfite is a white, crystalline solid and is used in various chemical processes.

4. MgSO3: Magnesium sulfite (MgSO3) is a compound formed when magnesium (Mg) reacts with sulfur dioxide (SO2). Magnesium sulfite is a white crystalline solid and is used in the production of paper and as a preservative in food.

Overall, the given sequence describes the conversion of elemental sulfur (S) to sulfur dioxide (SO2), followed by the formation of potassium sulfite (K2SO3) and ending with the production of magnesium sulfite (MgSO3).
