Question

S so2 h2so3 k2so3 so2 na2so3

Answer 1

Ответ:

Объяснение:

S+O2=SO2

SO2+H2O=H2SO3

H2SO3+2KOH=K2SO3+H2O

K2SO3(t)=K2O+SO2

SO2+2NaOH=Na2SO3+H2O

Answer 2

Ответ:

Объяснение:
S + O2 = SO2 (при взаимодействии серы с кислородом, образуется диоксид серы);

2) SO2 + H2O = H2SO3 (при взаимодействии диоксида серы с водой, образуется сернистая кислота);

3) H2SO3 + 2NaOH = Na2SO3 + 2H2O (при взаимодействии сернистой кислоты с гидроксидом натрия, образуется сульфит натрия и вода);

4) Na2SO3 + 2HCl = NaCl + H2SO3 (при взаимодействии сульфита натрия с соляной кислотой, образуется хлорид натрия и сернистая кислота);

5) H2SO3 + 2KOH = K2SO3 + 2H2O (при взаимодействии сернистой кислоты с гидроксидом калия, образуется сульфит калия и вода).

Answer 3

It seems like you have provided a list of chemical compounds. Here's some information about each compound:

1. SO2: This represents sulfur dioxide, a colorless gas with a strong, suffocating odor. It is formed during the combustion of sulfur-containing fuels and is a common air pollutant. Sulfur dioxide is also used as a reducing agent, preservative, and in various industrial processes.

2. H2SO3: This represents sulfurous acid, a weak acid formed by dissolving sulfur dioxide in water. It is not stable in its pure form and is typically handled as an aqueous solution. Sulfurous acid is used as a reducing agent and in some chemical reactions.

3. K2SO3: This represents potassium sulfite, an inorganic salt. It is composed of potassium cations (K+) and sulfite anions (SO3^2-). Potassium sulfite is used in various applications, such as in the production of chemicals, as a food preservative, and in the photography industry.

4. Na2SO3: This represents sodium sulfite, another inorganic salt. It is composed of sodium cations (Na+) and sulfite anions (SO3^2-). Sodium sulfite is commonly used in the pulp and paper industry, as a reducing agent, and in water treatment processes.

5. SO2: This compound, sulfur dioxide, has already been mentioned above.

Please note that chemical compounds can have different properties and applications depending on their context and the specific conditions of use. If you have any more specific questions or need further information about any of these compounds, feel free to ask!
