Question

A piece of magnesium is puy in a test tube containing hydrochloric acid. Explain the reaction with equation

Answer 1

Magnesium and Hydrochloric Acid



Discussion

Magnesium reacts with hydrochloric acid according to the equation: Mg(s) + 2 HCl(aq) --> MgCl2(aq) + H2(g) This demonstration can be used to illustrate the characteristic reaction of metals with acid, a single replacement reaction, or to demonstrate the generation of hydrogen gas. The flammability of hydrogen gas can be demonstrated by carefully holding a match or fireplace lighter up to the popping hydrogen bubbles. An audible crackling sound is heard as the hydrogen burns.

The net ionic equation for this reaction is: Mg(s) + 2H+(aq) --> Mg2+(aq) + H2(g)

Answer 2

Answer:

magnesium rectus with hydrochloric acid according to the equation :mg(s)+2hci(aq)=magci2(aq)+h2(g).the demonstration can be used to illustrate the characteristics reaction of metals with acid,a single replacement reaction ,or to demonstrate the genration of hydrogen gas.
