This is a sign of a chemical reaction.
A gas-evolution reaction is a type of chemical reaction that produces a gas as one of its products. This gas is usually released as a byproduct of the reaction and can sometimes be identified by observing bubbles forming in the reaction mixture. Examples include reactions that produce hydrogen gas, carbon dioxide, or oxygen.
A classic example of a reaction that can be classified in more than one way is the reaction of hydrochloric acid (HCl) with sodium bicarbonate (NaHCO₃). This reaction can be classified as both an acid-base reaction, where HCl donates a proton to the bicarbonate, and a gas evolution reaction, as it produces carbon dioxide (CO₂) gas. Additionally, it can also be considered a double displacement reaction, as the ions exchange partners.
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.
A gas is evolved as a product of a chemical reaction.

A gas-evolution reaction is a reaction that results in the formation of a gas.

Effervescence due to the evolution of gas is typically caused by a chemical reaction that produces carbon dioxide gas. This gas forms bubbles that rise to the surface. Examples include the reaction of an acid with a carbonate or bicarbonate compound.

A gas can be a reactant in a chemical reaction. For example, iron and the gas oxygen react to form rust, which is iron oxide.

Burning is an oxydation reaction.
The indicators of a chemical reaction are :- 1. Change in colour 2. Change in temperature 3. Evolution of a gas 4. Formation of a precipitate
In a displacement reaction, a more reactive element displaces a less reactive element from a compound. This is shown by the change in color, formation of a precipitate, or evolution of gas in the reaction mixture. The displacement reaction follows the pattern: A + BC -> AC + B.
In A Chemical Reaction the following take place a) there is evolution of a gas b) change in colour c) change in state d) change in temperature
