Question

S->So2->So3->NaHSo4->Na2So4->BaSo4

Answer 1

Ответ:

Объяснение:

S + O2 = SO2

2SO2 + O2 = 2SO3

SO3 + NaOH = NaHSO4

NaHSO4 + NaOH = Na2SO4 + H2O

Na2SO4 + BaCl2 = BaSO4 + 2NaCl

Answer 2

It looks like you've provided a sequence of chemical compounds, and it appears to represent a series of chemical reactions. Let's break down the given sequence:

1. S: This likely represents sulfur.

2. SO2: This is sulfur dioxide.

3. SO3: This is sulfur trioxide.

4. NaHSO4: This is sodium hydrogen sulfate, also known as sodium bisulfate.

5. Na2SO4: This is sodium sulfate.

6. BaSO4: This is barium sulfate.

Each compound in the sequence is related to the previous one through a chemical reaction. However, the specific reactions are not provided, so we can make some general observations about the transformations:

• Oxidation states: The sulfur in S undergoes changes in its oxidation state. It starts as elemental sulfur (S), then goes to sulfur dioxide (SO2), sulfur trioxide (SO3), and undergoes further changes in oxidation state in the subsequent compounds.

• Acid-base reactions: The transition from SO3 to NaHSO4 suggests the addition of a base (likely sodium hydroxide, NaOH) to SO3 to form a salt.

• Neutralization reactions: The formation of Na2SO4 from NaHSO4 suggests a neutralization reaction, possibly with sodium hydroxide.

• Precipitation reaction: The formation of BaSO4 from Na2SO4 suggests a precipitation reaction, where barium sulfate is formed as a solid precipitate.
