The equation 4HNO3 + Mg(OH)2 -> 2NO2 + 2H2O + Mg(NO3)2

  1. The chemical equation above describes the reaction process between nitric acid (HNO3) and magnesium hydroxide (Mg(OH)2), resulting in nitrogen dioxide gas (NO2), water (H2O), and magnesium nitrate (Mg(NO3)2).

  2. Reaction conditions: The reaction takes place at room temperature.

  3. Reaction process: When nitric acid reacts with magnesium hydroxide, the reaction occurs as follows:

    4HNO3 + Mg(OH)2 -> 2NO2 + 2H2O + Mg(NO3)2

    Where (HNO3) and (Mg(OH)2) are the reactants, and (NO2), (H2O), and (Mg(NO3)2) are the reaction products.

  4. Phenomenon: When the reaction occurs, brown nitrogen dioxide gas is released. This is the observable phenomenon when the reaction takes place.
