Question

write balanced chemical equations for the following chemical reactions and identify the type of reaction in

hydrogen + chlorine = hydrogen chloride

barium chloride + aluminium sulphate = barium sulphate + aluminium chloride ​

Answer 1

Answer :

$\bold{i.}\:\rm{H_2(g)+Cl_2(g)\longrightarrow{}2HCl(g)}$

• It's a combination reaction.

$\bold{ii.}\:\rm{3BaCl_2(aq)+Al_2(SO_4)_3(aq)\longrightarrow{}3BaSO_4(s)+2AlCl_3(aq)}$

• It's a double-displacement reaction. It is also a percipitatation reaction.

Additional Information :

Combination reaction:-

• A reaction in which a single product is formed from two or more reactants is called a combination reaction.
• Example: reaction of quicklime with water.

Double-displacement reaction:-

• A double-displacement reaction is a type of chemical reaction in which two compounds their ions to form new compounds.
• Example: reaction of sodium sulphate and barium chloride.

Precipitation reaction:-

• Any reaction that produces a percipitate (a insoluble solid mass) can be called a precipitation reaction.
