Question

Mg+HCL⇒Zn+HCL⇒Fe+HCL⇒

Answer 1

Mg+2HCl=MgCl2+ H2
Zn+2HCl=ZnCl2+H2
Fe+2HCl=FeCl2+H2

Answer 2

Mg+2HCL⇒MgCl2 + H2
Zn+2HCL⇒ ZnCl2 + H2
2Fe+6HCL⇒2FeCl3 + 3H2

Answer 3

The chemical equations you provided represent reactions between metals and hydrochloric acid (HCl). Here are the balanced chemical equations for each reaction:

1. Mg + 2HCl → MgCl2 + H2

In this reaction, magnesium (Mg) reacts with hydrochloric acid (HCl) to produce magnesium chloride (MgCl2) and hydrogen gas (H2).

2. Zn + 2HCl → ZnCl2 + H2

In this reaction, zinc (Zn) reacts with hydrochloric acid (HCl) to produce zinc chloride (ZnCl2) and hydrogen gas (H2).

3. Fe + 2HCl → FeCl2 + H2

In this reaction, iron (Fe) reacts with hydrochloric acid (HCl) to produce iron(II) chloride (FeCl2) and hydrogen gas (H2).

It's worth noting that these reactions are examples of metals displacing hydrogen from an acid to form metal chloride compounds.
