Question

differentiate between evolution of gas and formation of precipitate. [please give me answer of this question till tomorrow before 7:00am. I request you please]

Answer 1

Answer:

Gas evolution:

A gas evolution reaction is a chemical reaction in which one of the end products is a gas such as oxygen or carbon dioxide. Gas evolution reactions may be carried out in a fume chamber when the gases produced are poisonous when inhaled or explosive

Formation of precipitation:

Precipitation reactions are usually double displacement reactions involving the production of a solid form residue called the precipitate. These reactions also occur when two or more solutions with different salts are combined, resulting in the formation of insoluble salts that precipitate out of the solution.
