Answer 1

(A) The balanced chemical reaction will be:

`2KBr(aq)+Cl_2(g)\rightarrow 2KCl(aq)+Br_2(l)`

This reaction is a single replacement reaction.

(B) The balanced chemical reaction will be:

This reaction is a double displacement reaction.

(C) The balanced chemical reaction will be:

`N_2(g)+3H_2(g)\rightarrow 2NH_3(g)`

This reaction is a combination reaction.

Explanation :

Balanced chemical reaction : It is defined as the reaction in which the number of atoms of an element present on reactant side must be equal to the product side.

Part (A):

The balanced chemical reaction will be:

`2KBr(aq)+Cl_2(g)\rightarrow 2KCl(aq)+Br_2(l)`

This reaction is a single replacement reaction in which the most reactive element displaces the least reactive element from its solution.

Part (B):

The balanced chemical reaction will be:

`CaBr_2(aq) +H_2SO_4(aq)\rightarrow  CaSO_4(s)+2HBr(g)`

This reaction is a double displacement reaction in which a positive cation and a negative anion of two reactants exchange their places to form two new products.

Part (C):

The balanced chemical reaction will be:

`N_2(g)+3H_2(g)\rightarrow 2NH_3(g)`

This reaction is a combination reaction in which the two atoms combine to form a larger molecule.
