Answer: [tex]Mg(OH)_2\rightarrow  Mg^{2+}+2OH^–[/tex]
Explanation:
Ionization is a type of chemical reaction in which one reactant gives ions on decomposition.
[tex]A\rightarrow B^++C^-[/tex]
1. [tex]C+O_2\rightarrow CO_2[/tex] is an example of is an example of synthesis reaction in which two reactants are combining to form one product.
2. [tex]H_2CO_3\rightarrow H_2O+CO_2[/tex] is an example decomposition is a type of chemical reaction in which one reactant gives two or more than two products.
3. [tex]SO_2+H_2O\rightarrow HSO_3^-+H^+[/tex] : is an example of synthesis reaction in which two reactants are combining to form one product which being a strong electrolyte dissociate into ions.
4. [tex]Mg(OH)_2\rightarrow  Mg^{2+}+2OH^–[/tex] is an example of ionization in which one reactant gives ions on decomposition.
