Answer : The balanced chemical equation will be:
(i) [tex]2K+H_2SO_4\rightarrow K_2SO_4+H_2[/tex]
(ii) [tex]Mg(OH)_2+Zn\rightarrow Zn(OH)_2+Mg[/tex]
Explanation :
Balanced chemical equation : It is defined as the equation in which total number of individual atoms on the reactant side is equal to the total number of individual atoms on product side.
Part (i):
The balanced chemical equation will be:
[tex]2K+H_2SO_4\rightarrow K_2SO_4+H_2[/tex]
This reaction is a single displacement reaction in which most reactive element (potassium) displaces the least reactive element (hydrogen) form their solution.
Part (ii):
The balanced chemical equation will be:
[tex]Mg(OH)_2+Zn\rightarrow Zn(OH)_2+Mg[/tex]
This reaction is a single displacement reaction in which most reactive element (zinc) displaces the least reactive element (magnesium) form their solution.
