Question

Name the products formed in the following reactions. Support your answer with a word equation.

(i) reaction of hydrochloric acid with Zinc

(ii) a small piece of sodium dropped in water

(iii) Magnesium ribbon burns in air.​

Answer 1

The products of the reactions are as follows:

• When Zinc reacts with hydrochloric acid, it liberates hydrogen. The products formed are Zinc chloride and Hydrogen.

                Zn + 2HCl ⇒ ZnCl₂ + H₂

• When a small piece of sodium is dropped into water, the products formed are Sodium hydroxide and hydrogen.

                2Na + 2H₂O ⇒ 2NaOH + H₂

• When Magnesium ribbon burns in the air, the product formed is  Magnesium oxide.

                      Mg + O₂ ⇒ 2MgO
