Question

K --> K2O --> KOH --> KCl --> KNO3

Answer 1

2K + K₂O₂ = 2K₂O
K₂O + H₂O = 2KOH
KOH + HCl = KCl + H₂O
KCl + AgNO₃ = AgCl↓ + KNO₃

Answer 2

Potassium Chemical Reactions

The chemical reactions from K to K2O to KOH to KCl to KNO3 involve a series of transformations.

Potassium (K) can react with oxygen (O) to form potassium oxide (K2O). This reaction can be represented as:

2K + O2 → K2O Potassium oxide (K2O) can then react with water (H2O) to form potassium hydroxide (KOH). This reaction can be represented as:

K2O + H2O → 2KOH Potassium hydroxide (KOH) can react with hydrochloric acid (HCl) to form potassium chloride (KCl) and water (H2O). This reaction can be represented as:

KOH + HCl → KCl + H2O Finally, potassium chloride (KCl) can react with nitric acid (HNO3) to form potassium nitrate (KNO3) and hydrochloric acid (HCl). This reaction can be represented as:

KCl + HNO3 → KNO3 + HCl These reactions demonstrate the transformation of potassium through various chemical compounds, each formed through specific reactions with different substances.
