In KMnO4, Mn has an oxidation number of +7, KNO2 has N with an oxidation number of +3, and H2SO4 has S with an oxidation number of +6. In MnSO4, Mn has an oxidation number of +2, H2O has O with an oxidation number of -2, KNO3 has N with an oxidation number of +5, and K2SO4 has S with an oxidation number of +6.
2 KNO3 ↔ 2 KNO2 + O2
The given chemical reaction is a double displacement reaction, also known as a metathesis reaction. In this reaction, the cations and anions from two different compounds switch places to form new compounds: NaOH + KNO3 → NaNO3 + KOH.
The reaction between HNO3 (nitric acid) and KOH (potassium hydroxide) will form potassium nitrate (KNO3) and water (H2O).
When NaCl (sodium chloride) and KNO3 (potassium nitrate) are mixed together, no chemical reaction occurs as each compound remains as separate ions in solution. This is known as a physical mixture or a non-reactive mixture.
This is a decomposition reaction. KNO3 decomposes into KNO2 and O2 when heated.

No, the reaction represented by KCl + HNO3 → KNO3 + HCl is a double replacement reaction where ions in the reactants exchange to form new compounds in the products. In a single displacement reaction, one element replaces another in a compound.

The reaction between HNO3 (nitric acid) and KOH (potassium hydroxide) will form potassium nitrate (KNO3) and water (H2O).
The reaction between KCl and AgNO3 to form AgCl and KNO3 is an exothermic reaction. When these two ionic compounds react, they form a solid precipitate of silver chloride (AgCl) and release energy in the process. This release of energy indicates that the reaction is exothermic.
A precipitate
The reaction is the following:AgNO3 + KI = KNO3 = AgI(s)
When silver nitrate (AgNO3) reacts with potassium chloride (KCl), a double displacement reaction occurs. The silver ions (Ag+) in AgNO3 switch places with the potassium ions (K+) in KCl to form silver chloride (AgCl) and potassium nitrate (KNO3). This reaction is represented by the chemical equation: AgNO3 + KCl → AgCl + KNO3. Silver chloride is a white precipitate that forms when the two solutions are mixed, while potassium nitrate remains soluble in water.
In the reaction between potassium iodide (KI) and silver nitrate (AgNO3), a precipitation reaction occurs, resulting in the formation of silver iodide (AgI), which appears as a solid precipitate, and potassium nitrate (KNO3) in aqueous solution. The balanced equation for the reaction is: 2KI(aq) + AgNO3(aq) → AgI(s) + KNO3(aq). This reaction is commonly used in laboratory settings to demonstrate the formation of insoluble salts.
When NaCl (sodium chloride) and KNO3 (potassium nitrate) are mixed together, no chemical reaction occurs as each compound remains as separate ions in solution. This is known as a physical mixture or a non-reactive mixture.
