When a solution of sodium hydroxide is added to a solution of ammonium carbonate H20 is formed and ammonia gas NH3 is released when the solution is heated write the ionic equation for this reason both?

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.
Sulfur dioxide is released in the combustion of coal Scrubbers use lime slurries of calcium hydroxide to remove the SO2 from flue gases Write a balanced equation for this reaction?
CaO+SO2+H2O-->CaSO3+H2O
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
Which gas is evovled on heating sodium carbonate?
Na2CO3--------Na2O + CO2 Carbon dioxide is released by the thermal decomposition of sodium carbonate.

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.
How is carbon dioxide released into the air by carbonate rocks?
When acid rain reacts with the carbonate rocks, carbon dioxide is usually released into the air.
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.
Why containers containing ammonium chloride should always be kept in closed containers?
Ammonium chloride is easily decomposed and NH3 and HCl are released.
What gas or liquid is released from copper carbonate when heated?
Carbon dioxide is released.
Sulfur dioxide is released in the combustion of coal Scrubbers use lime slurries of calcium hydroxide to remove the SO2 from flue gases Write a balanced equation for this reaction?
CaO+SO2+H2O-->CaSO3+H2O
Why the ammonium salts have pungent smell?
Because ammonia can be released easily.
How can you seprate NaCl from NH4Cl?
Ammonium chloride may be released by heating.
