Question

a piece of magnesium is put in a test tube containing hydrochloric acid explain​

Answer 1

Answer:

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)
