Question

1.Barium Chloride (aq)+copper sulphate (aq)-->barium sulphate (s) + copper Chloride (aq)
2. magnesium (s) + hydrochloric acid(aq) --> magnesium chloride (aq) + hydrogen (g)
3. ammonia (g) + hydrogen chloride (g) --> ammonium chloride.

write balanced chemical equation and identify the reaction.​

Answer 1

Answer:

1. Balanced chemical equation :

• BaCl₂ (aq) + CuSo₄ (aq) → BaSo₄ (s) + CuCl₂ (aq)

This is Double displacement reaction beacuse here two compound Barium chloride and Copper sulphate are reacting by exchange of ions to form other two compounds Barium sulphate and Copper chloride.

2. Balanced chemical equation :

• Mg (s) + 2HCl (aq) → MgCl₂ (aq) + H₂ (g)

This is displacement reaction beacuse Magnisium is more reactive than hydrogen. So, Magnesium displace hydrogen to form Magnisium chloride.

3. Balanced chemical equation :

• NH₃ (g) + HCl (g) → NH₄Cl (s)

This is Combination reaction beacuse here, Ammonia and hydrogen chloride are reacting together to form a single compound ammonium chloride.

Answer 2

Required Answer :-

1) BaCI₂ + CuSO₄ ⇒ BaSO₄ + CuCI₂

Type - Double displacement reaction

2) Mg + 2HCI ⇒ MgCI₂ + H₂

Type - Displacement reaction

3) NH₃ + HCI ⇒ NH₄CI

Type - Combination reaction

Know More :-

Double displacement reaction - This reaction is define as changing the place from another atom.

Displacement reaction - This reaction is defined as a reaction in which an atom is changed with the help of compound.

Combination reaction - A combination reaction is a reaction in which two or more elements are formed to make a compound
