Question

magnesium displaces hydrogen from dilute HCL acid write the reaction ​

Answer 1

Answer:

Mg2 + 4 HCl = 2 MgCl2 + 2H2

Explanation:

Mg2 + 4 HCl = 2 MgCl2 + 2H2

metal plus acid gives displacement reaction....where Hydrigygets evolved......If you try this Experiment/reaction in lab with proper precautions.

by taking Mg particles in test tube and then pouring little amount of HCl (liquid form). you'll see gas coming out of it...which is Hydrogen. one can verify by just introducing fire...by lighter or matchstick. bubbles of hydrogen burst!

Answer 2

Answer:

Mg +2HCl ---> MgCl2 +H2

Magnesium reacts with hydrochloric acid and gives magnesium chloride and hydrogen gas..
