Question

write one balanced chemical equations represent that evolution of gas may occur decring a chemical reaction
​

Answer 1

Answer:

A common type of gas evolution reaction is an acid-base reaction, where an acid mixes with a base to produce water and carbon dioxide. ... For example, carbonic acid breaks down to water and carbon dioxide, sulfurous acid breaks down to water and sulfur dioxide, and ammonium hydroxide breaks down to water and ammonia gas.

A chemical reaction is usually accompanied by easily observed physical effects, such as the emission of heat and light, the formation of a precipitate, the evolution of gas, or a color change. Absolute confirmation of a chemical change can only be validated by chemical analysis of the products!
