Question

N2=>N2O3=>HNO3=>Mg(NO3)2=>KNO3

Answer 1

2N2 + 3O2 = 2N2O3

N2O3 (t)= NO + NO2

4NO2 + 2H2O + O2 = 4HNO3

Mg(OH)2 + 2HNO3 = Mg(NO3)2 + 2H2O

Mg(NO3)2 + 2KOH = Mg(OH)2 + 2KNO3

Answer 2

The chemical reactions you provided are a series of transformations starting with N2 and leading to KNO3. Let's go through each step:

1. N2 to N2O3: The reaction between nitrogen gas (N2) and oxygen gas (O2) can form nitrogen trioxide (N2O3) under specific conditions. The balanced equation for this reaction is:

   N2 + O2 → 2N2O3

2. N2O3 to HNO3: Nitrogen trioxide (N2O3) can react with water (H2O) to produce nitric acid (HNO3). The balanced equation is:

   N2O3 + H2O → 2HNO3

3. HNO3 to Mg(NO3)2: Nitric acid (HNO3) can react with magnesium (Mg) to form magnesium nitrate (Mg(NO3)2) and hydrogen gas (H2). The balanced equation is:

   8HNO3 + 3Mg → 3Mg(NO3)2 + 4H2O + 2NO + NO2

   Note: This reaction also produces nitrogen monoxide (NO) and nitrogen dioxide (NO2) as byproducts.

4. Mg(NO3)2 to KNO3: Magnesium nitrate (Mg(NO3)2) can undergo a double displacement reaction with potassium chloride (KCl) to form potassium nitrate (KNO3) and magnesium chloride (MgCl2). The balanced equation is:

   Mg(NO3)2 + 2KCl → 2KNO3 + MgCl2

   Note: This reaction involves the exchange of ions between the compounds.

By following these reactions, you can convert N2 into KNO3 via the intermediates N2O3, HNO3, and Mg(NO3)2.
