Question

1)seo2-se-h2seo3-h2seo4-baseo4 2)fes2-so2-so3-h2so4-al2(so4)3-k2so4-baso4​

Answer 1

Ответ:

1) SeO2 + 2H2S → Se + 2S + 2H2O (вода)

Se + 4HNO3 → H2SeO3 + 4NO2↑ + H2O (вода)

H2SeO3  + H2O2 → H2SeO4 + H2O (вода)

H2SeO4 + Ba(OH)2 → BaSeO4 + 2H2O (вода)

2) 4FeS + 7O2 → Fe2O3 + 4SO2↑

2SO2 + O2 → 2SO3↑

SO3 + H2O → H2SO4

2Al + 3 H2SO4 → Al2(SO4)3 + 3H2↑

Al2(SO4)3 + 6KOH → 3K2SO4 + 2Al(OH)3↓

K2SO4 + Ba(OH)2 → BaSO4↓ + 2KOH

Answer 2

It seems like you've provided two chemical equations. I'll break down each one for you:

1. Chemical Equation 1:

• seo2: This likely refers to selenium dioxide (SeO2).
• se-h2seo3: This represents a reaction where selenium dioxide (SeO2) reacts with hydrogen gas (H2) to form selenium trioxide (SeO3).
• h2seo4: This might represent another reaction where selenium trioxide (SeO3) reacts with hydrogen gas (H2) to form selenium tetraoxide (SeO4).
• baseo4: I'm not sure what "baseo4" represents in this context. It's not a commonly known chemical compound.

Please provide more context or information if you need further clarification or details on this equation.

2. Chemical Equation 2:

• fes2: This represents iron disulfide, commonly known as pyrite (FeS2).
• so2: This represents sulfur dioxide (SO2).
• so3: This represents sulfur trioxide (SO3).
• h2so4: This represents sulfuric acid (H2SO4).
• al2(so4)3: This represents aluminum sulfate (Al2(SO4)3).
• k2so4: This represents potassium sulfate (K2SO4).
• baso4: This represents barium sulfate (BaSO4).

It seems like you have a sequence of reactions or transformations involving these compounds. If you have specific questions or need more information about any part of this equation, please feel free to ask.
