Question

K2SO4→KOH→K2S→KNO3 ↓ KCl→K​

Answer 1

1) K2SO4 + Ba(OH)2 = 2KOH + BaSO4
2) 2KOH + H2S = K2S + 2H2O
3) K2S + Pb(NO3)2 = 2KNO3 + PbS
4) KOH + HCl = KCl + H2O
5) KCl + Li = LiCl + K

Answer 2

The chemical reaction you provided seems to be a series of transformations involving potassium (K) and various anions. Let's break it down step by step:

1. K2SO4 → KOH: In this reaction, potassium sulfate (K2SO4) reacts with water (H2O) to form potassium hydroxide (KOH) and sulfuric acid (H2SO4).

2. KOH → K2S: In this step, potassium hydroxide (KOH) reacts with elemental sulfur (S) to produce potassium sulfide (K2S) and water (H2O).

3. K2S → KNO3: This transformation involves the oxidation of potassium sulfide (K2S). The K2S reacts with nitric acid (HNO3) to form potassium nitrate (KNO3) and hydrogen sulfide gas (H2S).

4. KCl → K: This reaction represents the reduction of potassium chloride (KCl). By subjecting KCl to high temperature and electrolysis, it can be reduced to elemental potassium (K).

It's important to note that the arrow you provided, "↓," typically represents a reduction reaction. However, in the case of the transformation from K2S to KNO3, it involves an oxidation reaction, not a reduction.
