Evolution of gas with examples
Answers
Answer:
A gas evolution reaction is a chemical reaction in which one of the end products is a gas such as oxygen or carbon dioxide.[1][2] Gas evolution reactions may be carried out in a fume chamber when the gases produced are poisonous when inhaled or explosive.
Examples Edit
Examples EditA replacement reaction concerning zinc metal and hydrogen chloride:
Examples EditA replacement reaction concerning zinc metal and hydrogen chloride:Zn + 2 HCl → ZnCl
Examples EditA replacement reaction concerning zinc metal and hydrogen chloride:Zn + 2 HCl → ZnCl2 + H
Examples EditA replacement reaction concerning zinc metal and hydrogen chloride:Zn + 2 HCl → ZnCl2 + H2 (gas)
Examples EditA replacement reaction concerning zinc metal and hydrogen chloride:Zn + 2 HCl → ZnCl2 + H2 (gas)In this example, hydrogen gas in diatomic form is released.
Examples EditA replacement reaction concerning zinc metal and hydrogen chloride:Zn + 2 HCl → ZnCl2 + H2 (gas)In this example, hydrogen gas in diatomic form is released.A replacement reaction where gaseous hydrogen chloride and fluorine gas react to release diatomic chlorine gas (because fluorine is more electronegative):
