Explanation
Choice (B) shows the correct equation for this endothermic reaction:
NH4NO3 + H2O + Energy → NH4OH + HNO3
This is correct because:
1. It shows ammonium nitrate (NH4NO3) and water (H2O) as reactants, which aligns with the given information about placing solid ammonium nitrate in water.
2. It produces ammonium hydroxide (NH4OH) and nitric acid (HNO3) as products.
3. It correctly indicates an endothermic reaction by showing energy input on the reactant side.
The equation is balanced:
- 1 N, 4 H, and 4 O atoms on each side
- Charges are balanced
This equation accurately represents the endothermic dissolution of ammonium nitrate in water, which absorbs heat from the surroundings to break the ionic bonds and form the resulting aqueous solution containing ammonium and nitrate ions (represented here as NH4OH and HNO3).
