Question

Assume you have a highly magnified view of a solution of HCl that allows you to “see” the HCl. Draw this magnified view. If you dropped in a piece of magnesium, the magnesium would disappear and hydrogen gas would be released. Represent this change using symbols for the elements, and write out the balanced equation.

Answer 1

2HCl(aq)+Mg(s)----->MgCl2(aq)+H2(g)

In an aqueous solution of HCl, there is H+ ions and CL- ions. (Magnified View)
**ignore the OH- ions present in water which hydrochloric acid dissolve into**

When magnesium is dropped inside the hydrochloric acid, the magnesium will react with hydrochloric acid to form aqueous solution of magnesium chlorine and give out hydrogen gas.

Then in the solution, there will be Mg2+ ions and Cl- ions (Magnified View)
**ignore the OH- ions present in water which hydrochloric acid dissolve into**
