Question

1)K→KOH→Cu(OH)2→CuO→Cu2)SO2 →H2SO3→K2SO3→H2SO3→MgSO3

Answer 1

2K+H2O=H2+2KOH
KOH+CuSO4=K2SO4+Cu(OH)2
Cu(OH)2=CuO+H2O термическое разложение
CuO+Mg=MgO+Cu нагрев

SO2+H2O=H2SO3
2KOH+H2SO3=2H2O+K2SO3
K2SO3+H2SO4=K2SO4+H2SO3
Mg+H2SO3=H2+MgSO3

Answer 2

Chemical Reactions:

1) K → KOH → Cu(OH)2 → CuO → Cu: The given sequence represents a series of chemical reactions involving potassium (K) and copper (Cu). Here is a breakdown of the reactions:

- K reacts with water (H2O) to form potassium hydroxide (KOH). - KOH reacts with copper(II) ions (Cu2+) to form copper(II) hydroxide (Cu(OH)2). - Cu(OH)2 can undergo thermal decomposition to form copper(II) oxide (CuO) and water (H2O). - Finally, CuO can react with hydrogen (H2) to produce copper (Cu).

2) SO2 → H2SO3 → K2SO3 → H2SO3 → MgSO3: The given sequence represents a series of chemical reactions involving sulfur dioxide (SO2), sulfuric acid (H2SO3), potassium sulfite (K2SO3), and magnesium sulfite (MgSO3). Here is a breakdown of the reactions:

- SO2 can react with water (H2O) to form sulfurous acid (H2SO3). - H2SO3 can react with potassium hydroxide (KOH) to produce potassium sulfite (K2SO3). - K2SO3 can react with water (H2O) to regenerate sulfurous acid (H2SO3). - Finally, H2SO3 can react with magnesium hydroxide (Mg(OH)2) to form magnesium sulfite (MgSO3).

Please note that the reactions mentioned above are simplified representations and may involve specific reaction conditions, stoichiometry, and catalysts that are not explicitly mentioned in the given sequence.
