Question

MgSO3-SO2-H2SO3-Na2SO3-Na2SO4

Answer 1

Ответ:

Объяснение:

MgSO3 + 2HCl = MgCl2 + SO2↑ + H2O

SO2 + H2O = H2SO3

H2SO3 + 2NaOH = Na2SO3 + 2H2O

Na2SO3 + MgSO4 = MgSO3↓ + Na2SO4

Answer 2

The chemical compounds you mentioned are all related to sulfur and its various oxidation states. Here's a breakdown of each compound:

1. MgSO3: This compound is magnesium sulfite. It consists of magnesium (Mg) and sulfite ions (SO3^2-). Sulfite is the oxidized form of sulfur with a charge of 2-.

2. SO2: This compound is sulfur dioxide. It consists of one sulfur atom and two oxygen atoms. Sulfur dioxide is a colorless gas with a pungent odor and is formed during the combustion of sulfur-containing fuels. It is also produced in volcanic eruptions and some industrial processes.

3. H2SO3: This compound is sulfurous acid. It consists of two hydrogen atoms (H) and sulfite ions (SO3^2-). Sulfurous acid is a weak acid that forms when sulfur dioxide dissolves in water.

4. Na2SO3: This compound is sodium sulfite. It consists of sodium ions (Na^+) and sulfite ions (SO3^2-). Sodium sulfite is a white crystalline solid and is commonly used as a reducing agent in various chemical reactions.

5. Na2SO4: This compound is sodium sulfate. It consists of sodium ions (Na^+) and sulfate ions (SO4^2-). Sodium sulfate is a white crystalline solid and is used in various industrial applications, including as a drying agent, in the manufacture of detergents, and in the production of paper and textiles.

Each compound in your list represents different oxidation states of sulfur, ranging from +4 in sulfite (SO3^2-) to +6 in sulfate (SO4^2-).
