When ammonium carbonate decomposes, what would happen to a glowing splint in the presence of the gases that are evolved. Explain
(NH4)2CO3 ==> 2NH3 + CO2 + H2O
CO2 is carbon dioxide gas and that suffocates any flame.
Well, when ammonium carbonate decomposes, it releases a bunch of gases, including ammonia (NH3), carbon dioxide (CO2), and water vapor (H2O). Now, if you were to put a glowing splint in the presence of these gases, you'd have quite the circus act!
First, ammonia being a gas that is lighter than air, would float up and tickle the glowing splint. It might even make the splint do a little dance, but it won't extinguish the flame. The splint would keep on glowing like a flamenco dancer on caffeine.
Next, carbon dioxide would join the party. It has no time for silly splints, so it would just stay put, hanging around the splint like a wallflower at a dance. It wouldn't make the splint stop glowing, but it might make it feel a little self-conscious.
Lastly, water vapor, being the sneaky molecule it is, would try to cool down the glowing splint, giving it a refreshing mist like a fancy spa treatment. This might cause the flame to flicker for a short while, but the splint would persist and keep glowing, defying the odds.
So, in conclusion, the presence of the gases evolved from the decomposition of ammonium carbonate won't extinguish the glowing splint. It might add some entertainment value, but the splint will continue to shine on.
When ammonium carbonate (NH4)2CO3 decomposes, it produces three gases: ammonia (NH3), carbon dioxide (CO2), and water vapor (H2O). In the presence of these evolved gases, the glowing splint would undergo specific changes.
1. Ammonia (NH3): Ammonia is a colorless gas with a pungent smell. It is alkaline in nature and reacts with water to form ammonium hydroxide (NH4OH). When the glowing splint is exposed to ammonia gas, the flame of the splint would extinguish due to the alkaline nature of ammonia. Ammonia acts as a base and suppresses the combustion reaction, thus causing the flame to go out.
2. Carbon dioxide (CO2): Carbon dioxide is a colorless and odorless gas. It is non-flammable and does not support combustion. If the glowing splint comes in contact with carbon dioxide gas, the flame would not be affected. Carbon dioxide is inert and does not react with the splint or support the burning process.
3. Water vapor (H2O): Water vapor is formed as a product of the decomposition of ammonium carbonate. It is produced when the hydrogen (H) and hydroxide (OH) ions from ammonium hydroxide combine. The presence of water vapor would not directly affect the glowing splint. However, if the water vapor condenses on the splint, it could potentially cause the splint to extinguish.
In summary, when ammonium carbonate decomposes, the glowing splint would be affected by the evolved gases differently. The flame would extinguish in the presence of ammonia due to its alkaline properties, while carbon dioxide and water vapor would have no direct effect on the flame, although water vapor could potentially cause the splint to go out if it condenses on it.
To determine what would happen to a glowing splint in the presence of the gases evolved from the decomposition of ammonium carbonate, we need to understand the composition of the gases.
Ammonium carbonate (NH4)2CO3 can decompose into three gases: ammonia (NH3), carbon dioxide (CO2), and water vapor (H2O).
First, let's analyze the reaction:
(NH4)2CO3 → 2NH3 + CO2 + H2O
Now, let's consider the effect of each gas on the glowing splint:
1. Ammonia (NH3): Ammonia is a colorless gas with a strong pungent odor. When a glowing splint is introduced to ammonia gas, it extinguishes the flame. This happens because ammonia gas acts as a "non-supporter of combustion" or a fire extinguisher. It reacts with the oxygen present in the glowing splint, displacing it and preventing further combustion.
2. Carbon Dioxide (CO2): Carbon dioxide is a colorless gas that does not support combustion. It is also denser than air. However, unlike ammonia, carbon dioxide doesn't itself extinguish a flame. Instead, it can displace oxygen from the air surrounding the glowing splint, effectively reducing the amount of oxygen available for combustion. This displacement effect can eventually lead to the extinguishing of the burning splint.
3. Water Vapor (H2O): Water vapor is the gaseous phase of water. It does not actively contribute to extinguishing the burning splint. However, if the decomposition of ammonium carbonate is carried out at a high temperature, the water vapor produced may condense on the glowing splint and quickly extinguish it due to the cooling effect.
In summary, when ammonium carbonate decomposes, the evolved gases, namely ammonia, carbon dioxide, and water vapor, can all potentially contribute to extinguishing a glowing splint. Ammonia and carbon dioxide act as non-supporters of combustion, while water vapor can condense and cool down the splint.
