Question

Пожалуйстаааа помогите!!! Выполнить схемы превращений: 1)С- СО2- Н2СО3- К2СО3- КF 2)S- SO3- H2SO4 -Na2SO4 -CaSO4 3)K- K2O- KCl- KNO3- NaNO3

Answer 1

C + O₂ =CO₂

CO₂ + H₂O= H₂CO₃

H₂CO₃ + 2KOH= K₂CO₃ +2 H₂O .

2S+302→SO3

SO3+H2O→H2SO4

H2SO4+2NaCL→Na2SO4+2HCL

Na2SO4+Ca(OH)2→CaSO4+2NaOH .

2K + K₂O₂ = 2K₂O

K2O + 2 HCl → 2 KCl + H2O

KCl + AgNO₃ = AgCl↓ + KNО₃

KNO3+ NaCl→ NaNO3+ KCl .

Answer 2

Scheme 1: Conversion of S to KF

To convert S to KF, we need to go through several steps. Here's the step-by-step process:

1. S to SO2: Sulfur (S) can be converted to sulfur dioxide (SO2) by burning it in the presence of oxygen. The balanced chemical equation for this reaction is:

S + O2 → SO2

2. SO2 to H2SO4: Sulfur dioxide (SO2) can be further oxidized to sulfuric acid (H2SO4) by reacting it with oxygen and water. The balanced chemical equation for this reaction is:

SO2 + O2 + H2O → H2SO4

3. H2SO4 to H2CO3: Sulfuric acid (H2SO4) can react with water (H2O) to form carbonic acid (H2CO3). The balanced chemical equation for this reaction is:

H2SO4 + H2O → H2CO3

4. H2CO3 to K2CO3: Carbonic acid (H2CO3) can be converted to potassium carbonate (K2CO3) by reacting it with potassium hydroxide (KOH). The balanced chemical equation for this reaction is:

H2CO3 + 2 KOH → K2CO3 + 2 H2O

5. K2CO3 to KF: Finally, potassium carbonate (K2CO3) can be converted to potassium fluoride (KF) by reacting it with hydrofluoric acid (HF). The balanced chemical equation for this reaction is:

K2CO3 + 2 HF → 2 KF + CO2 + H2O

So, the complete scheme for converting S to KF is as follows:

S → SO2 → H2SO4 → H2CO3 → K2CO3 → KF

Scheme 2: Conversion of S to CaSO4

To convert S to CaSO4, we need to go through several steps. Here's the step-by-step process:

1. S to SO3: Sulfur (S) can be converted to sulfur trioxide (SO3) by reacting it with oxygen. The balanced chemical equation for this reaction is:

2 S + 3 O2 → 2 SO3

2. SO3 to H2SO4: Sulfur trioxide (SO3) can react with water (H2O) to form sulfuric acid (H2SO4). The balanced chemical equation for this reaction is:

SO3 + H2O → H2SO4

3. H2SO4 to Na2SO4: Sulfuric acid (H2SO4) can react with sodium hydroxide (NaOH) to form sodium sulfate (Na2SO4). The balanced chemical equation for this reaction is:

H2SO4 + 2 NaOH → Na2SO4 + 2 H2O

4. Na2SO4 to CaSO4: Sodium sulfate (Na2SO4) can be converted to calcium sulfate (CaSO4) by reacting it with calcium chloride (CaCl2). The balanced chemical equation for this reaction is:

Na2SO4 + CaCl2 → CaSO4 + 2 NaCl

So, the complete scheme for converting S to CaSO4 is as follows:

S → SO3 → H2SO4 → Na2SO4 → CaSO4

Scheme 3: Conversion of K to NaNO3

To convert K to NaNO3, we need to go through several steps. Here's the step-by-step process:

1. K to K2O: Potassium (K) can be converted to potassium oxide (K2O) by reacting it with oxygen. The balanced chemical equation for this reaction is:

4 K + O2 → 2 K2O

2. K2O to KCl: Potassium oxide (K2O) can react with hydrochloric acid (HCl) to form potassium chloride (KCl). The balanced chemical equation for this reaction is:

K2O + 2 HCl → 2 KCl + H2O

3. KCl to KNO3: Potassium chloride (KCl) can be converted to potassium nitrate (KNO3) by reacting it with nitric acid (HNO3). The balanced chemical equation for this reaction is:

KCl + HNO3 → KNO3 + HCl

4. KNO3 to NaNO3: Finally, potassium nitrate (KNO3) can be converted to sodium nitrate (NaNO3) by reacting it with sodium chloride (NaCl). The balanced chemical equation for this reaction is:

KNO3 + NaCl → NaNO3 + KCl

So, the complete scheme for converting K to NaNO3 is as follows:

K → K2O → KCl → KNO3 → NaNO3
