Question

Equation for the reaction of magnesium aluminium zinc and iron with dilute hydrochloric acid

Answer 1

more reactive metal displaces hydrogen from hydrochloric acid.

Mg + 2Hcl ---- MgCl2 + H2

2Al + 6Hcl ---- 2AlCl3 + 3H2

Fe + 2HCl ----- FeCl2 + H2

Answer 2

Answer: The equations for the following is given below.

Explanation:

Magnesium, Iron and Zinc are the metals and when it is reacted with an acid, it produces salt and hydrogen gas.

• The equation for the reaction of magnesium with dilute hydrochloric acid follows:

$Mg(s)+2HCl(aq.)\rightarrow MgCl_2(aq.)+H_2(g)$

1 mole of Magnesium reacts with 2 moles of hydrochloric acid to produce 1 mole of magnesium chloride and 1 mole of hydrogen gas.

• The equation for the reaction of zinc with dilute hydrochloric acid follows:

$Zn(s)+2HCl(aq.)\rightarrow ZnCl_2(aq.)+H_2(g)$

1 mole of Zinc reacts with 2 moles of hydrochloric acid to produce 1 mole of zinc chloride and 1 mole of hydrogen gas.

• The equation for the reaction of iron with dilute hydrochloric acid follows:

$Fe(s)+2HCl(aq.)\rightarrow FewCl_2(aq.)+H_2(g)$

1 mole of Iron reacts with 2 moles of hydrochloric acid to produce 1 mole of iron chloride and 1 mole of hydrogen gas.
