When a gas is released as a byproduct of a chemical reaction, it is referred to as gas evolved. This gas is usually observed as bubbles forming or a visible release of gas during the reaction. Examples include the evolution of oxygen in the electrolysis of water or the release of carbon dioxide in the reaction between baking soda and vinegar.

Which gas is evolved when KMnO4 reacts with H2C2O4?
The evolved gas is carbon dioxide (CO2).
Which gas is evolved during photosynthesis?
Oxygen gas is evolved during photosynthesis as a byproduct of the light-dependent reactions in the chloroplasts of plant cells.
What is the test for the gas evolved when sodium hydrogen carbonate is added to acetic acid?
The gas evolved is carbon dioxide. The test is that it turns lime water milky.
When calcium metal is placed in water is added to water the gas evolved does not catch fire but the same gas on adding sodium metal cathches fire why'?
In both reactions hydrogen gas is released but heat evolved in the sodium reaction is bigger.
What is the formula and color of the gas that is evolved?
The formula for the gas evolved during the reaction depends on the reactants involved. Common examples include hydrogen gas (H2), oxygen gas (O2), carbon dioxide (CO2), or chlorine gas (Cl2), among others. The color of the gas can vary depending on the specific gas being produced - for example, hydrogen is colorless and odorless, while chlorine gas is yellow-green in color.
