Question

A/ H²0²→O²→ H²O → H²SO³​

Answer 1

Ответ:

1. 2H2O=2H2↑+02↑

2.h2+02=h20

3.h2o+s02=h2so3

Answer 2

Ответ:

2H2O2 = 2H2O + O2

H2 + O2 = H2O

H2S + 3H2O = H2SO3 + 3H2

Answer 3

It seems like you've provided a chemical equation or a sequence of chemical reactions. Let's break it down step by step:

1. A + H₂O₂ → O₂ This represents a reaction where some substance "A" reacts with hydrogen peroxide (H₂O₂) to produce oxygen gas (O₂).

2. O₂ → H₂O This represents the conversion of oxygen gas (O₂) to water (H₂O). This is typically a combustion or oxidation reaction.

3. H₂O → H₂SO₃ This represents a reaction where water (H₂O) reacts to form sulfuric acid (H₂SO₃).

Please note that the reactions as written are somewhat simplified and may not fully represent the actual reaction mechanisms or stoichiometry involved. Also, you haven't provided the specific substances or conditions involved, so it's difficult to provide more detailed information. If you have any specific questions or if you need more information about any of these reactions, please feel free to ask.
