Answer:
The solution turns purple because ammonia is a base.
The solution turned red.
Ammonia gas is neutral, but ammonia solution ( ammonium hydroxide ) is a base.
Adding vinegar to ammonia suppresses its dissociation hence decrease in hydroxyl ion concentration.
If more ammonia is added to the solution, the pink color re-appears.
Answer:
The unbalanced chemical equation: H₂O₂ → H₂O + O₂.
The balanced chemical equation: H₂O₂ → H₂O + 1/2O₂.
Explanation:
- Hydrogen peroxide is decomposed into oxygen and water, which is a slow reaction.
- It is can be catalyzed by using yeast.
The unbalanced chemical equation: H₂O₂ → H₂O + O₂.
The balanced chemical equation: H₂O₂ → H₂O + 1/2O₂.
1.0 mol of H₂O₂ is decomposed to 1.0 mol of H₂O and 0.5 mol of O₂.
