Tartaric acid plus potassium carbonate react to form carbon dioxide gas.
Tartaric acid and potassium carbonate react to form potassium bitartrate (cream of tartar), water, and carbon dioxide gas.
I'm no specialist on this, but I'd say CO2. Leaving CaO as a residue of course...
- 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.
Oxygen gas is given off when potassium permanganate is broken down. Potassium permanganate decomposes into manganese dioxide, potassium hydroxide, and oxygen gas when heated.
When solid potassium oxide (K2O) is added to a container of carbon dioxide (CO2) gas, a chemical reaction occurs. Potassium oxide reacts with carbon dioxide to form potassium carbonate (K2CO3). This reaction is a double displacement reaction, where the potassium from potassium oxide replaces the carbon in carbon dioxide, resulting in the formation of potassium carbonate. The balanced chemical equation for this reaction is: K2O + CO2 → K2CO3.

Ammonia gas and carbon dioxide gas are given off when ammonium carbonate decomposes.
Carbon dioxide (CO2) is removed from the air by potassium hydroxide. Potassium hydroxide reacts with CO2 to form potassium carbonate and water, thereby removing the CO2 gas from the air.
When potassium sorbate is heated, it may decompose into potassium carbonate, carbon dioxide, and water vapor. This decomposition process can lead to the release of carbon dioxide gas and create a foul odor. It is important to heat potassium sorbate cautiously and in a well-ventilated area to prevent any potential hazards.
I have no idea. The products of that reaction are water (not a gas at room temperature) and potassium chloride (not a gas at room temperature).
When sulfuric acid reacts with potassium hydrogen carbonate, it forms potassium sulfate, carbon dioxide gas, and water. This reaction is a double displacement reaction where the hydrogen in the acid is replaced by the potassium. The carbon dioxide gas bubbles out of the solution.
The bubbling observed is due to the release of carbon dioxide gas when the potassium carbonate reacts with hydrochloric acid. This reaction forms potassium chloride, water, and carbon dioxide.
