Write Balanced Chemical Equations for the Following (including ALL physical states)

Question

1. Gaseous nitrogen dioxide reacts with liquid water to produce nitric acid and gaseous nitrogen monoxide.

2. Solid iodine reacts with chlorine gas to produce liquid iodine trichloride.

3. Sodium bicarbonate when heated will form solid sodium carbonate, carbon dioxide and water vapor.

Answer 1

1. Gaseous nitrogen dioxide (NO₂) reacts with liquid water (H₂O) to produce nitric acid (HNO₃) and gaseous nitrogen monoxide (NO).

3NO₂(g) + H₂O(l) ==> 2HNO₃(aq) + NO(g) ... balanced equation

2. Solid iodine (I₂) reacts with chlorine gas (Cl₂) to produce liquid iodine trichloride (ICl₃).

I₂(s) + 3 Cl₂(g) ==> 2 ICl₃(l) ... balanced equation

3. Sodium bicarbonate (NaHCO₃) when heated will form solid sodium carbonate (Na₂CO₃), carbon dioxide (CO₂) and water vapor (H₂O).

2NaHCO₃(s) ===> Na₂CO₃(s) + CO₂(g) + H₂O(g) ... balanced equation
