write a few points about reactions that evolve gas
Answers
Answer:
Gas evolution reactions
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.
Answer:
A gas evolution reaction is a chemical process that produces a gas, such as oxygen or carbon dioxide.
Explanation:
key points: Acids react with carbonates to produce a salt, carbon dioxide, and water.
Acids react with carbonates to produce a salt, carbon dioxide, and water.Limewater can be used to detect the presence of carbon dioxide evolved in a reaction.
