The first ionic equation is: OH- (aq) + NH4+ (aq) -> NH3 (aq) + H2O.
The change upon heating described in the question is physical only and does not involve ions; the dissolved ammonia simply passes from the aquated state to the gas phase, because the solubility of gases in liquids decreases with increasing temperature.

Which type of chemical reaction takes place when barium hydroxide and ammonium chloride are mixed together in terms of heat released or absorbed?
The chemical reaction between barium hydroxide and ammonium chloride to form barium chloride, ammonia and water is characterised by a change in temperature (which is fall in temperature). It is a endothermic reaction (which means heat absorbing reaction). Ba(OH)2 + NH4Cl ------------> BaCl2 + NH3 + H2O
Chemical test can distinguish sodium carbonate form potassium hydroxide?
- use a flame test to distinguish between sodium and potassium - use flame photometry to determine sodium and potassium - heat sodium carbonate and collect the gas in a beaker with water: the gas released is carbon dioxide; see the bubbles. Measure the pH; it will be more than 7.
What is potassium hydroxide used for in an experiment to demonstrate that carbon dioxide is produced by green plants during respiration?
Potassium hydroxide is used to absorb carbon dioxide produced by the green plant during respiration. By placing the potassium hydroxide in the experimental setup, any carbon dioxide released will be absorbed, preventing it from affecting the results of the experiment. This allows for the accurate measurement of how much carbon dioxide is produced by the plant during respiration.
Will sodium carbonate react with hydrochloric acid. What is the ionic and net ionic equation?
Yes, it will neutralize the HCl and form carbonic acid, which is not stable and decomposes to form CO2. The overall reaction is: Na2CO3 + 2HCl ---> 2NaCl + H2O + CO2, and takes place in two stages: Stage I: sodium carbonate is converted to sodium hyrogen carbonate (NaHCO3) as shown in the reaction: Na2CO3 + HCl ---> NaHCO3 + NaCl Stage II: the gas, carbon dioxide is released NaHCO3 + HCl ---> NaCl + H20 + CO2 The net ionic equation is: CO32- + 2H+ ---> H2O + CO2
What happens when sulphuric acid reacts with sodium hydroxide?
When sulfuric acid reacts with sodium hydroxide, a neutralization reaction occurs producing water and sodium sulfate as products. The balanced chemical equation for this reaction is: H2SO4 + 2NaOH -> 2H2O + Na2SO4.

When ammonium carbonate decomposes what would happen to a glowing splint in the presence of the gases that are evoled?
When ammonium carbonate decomposes, ammonia gas is released. If a glowing splint is introduced to the ammonia gas, the splint would extinguish due to the lack of oxygen in the gas. Ammonia gas does not support combustion.
If Ammonium chloride is heated with calcium hydroxide the products formed are ammonia water and calcium chloride Balance this equation?
2NH4Cl + Ca(OH)2 >> CaCl2 + 2NH3 + 2H2O When ammonia chloride is heated with calcium hydroxide, ammonia gas is released. Ammonia gas is less dense than air so it is collected in an upside down test tube, by the downward displacement of air. The water formed is often seen as droplets on the side of the test tube. the ammonia gas causes the damp red litmus to change to blue because a solution of ammonia gas is alkaline.

Can you prepare ammonia using calcium oxide and ammonium chloride?
Yes. Ammonium salts such as ammonium chloride will react with a strong base to yield ammonia.
What is potassium hydroxide used for in an experiment to demonstrate that carbon dioxide is produced by green plants during respiration?
Potassium hydroxide is used to absorb carbon dioxide produced by the green plant during respiration. By placing the potassium hydroxide in the experimental setup, any carbon dioxide released will be absorbed, preventing it from affecting the results of the experiment. This allows for the accurate measurement of how much carbon dioxide is produced by the plant during respiration.
Why containers containing ammonium chloride should always be kept in closed containers?
Ammonium chloride is easily decomposed and NH3 and HCl are released.

How can you seprate NaCl from NH4Cl?
Ammonium chloride may be released by heating.

When sulfuric acid reacts with sodium hydroxide, a neutralization reaction occurs producing water and sodium sulfate as products. The balanced chemical equation for this reaction is: H2SO4 + 2NaOH -> 2H2O + Na2SO4.
What gas or liquid is released from copper carbonate when heated?
Carbon dioxide is released.
What is the ammonia that is released in smelling salts?
The ammonia released in smelling salts is a compound called ammonium carbonate ((NH4)2CO3). When exposed to air, this compound breaks down to release ammonia gas, which triggers a reflexive inhalation response and helps revive a person who has fainted.
