Question

Which is an example of ionization?

C + O2  CO2

H2CO3  H2O + CO2

SO2 + H2O  HSO3– + H+

Mg(OH)2  Mg2+ + 2OH–

Answer 1

Ionization is a formation of ions from neutral atoms or molecules.

SO₂ + H₂O = HSO₃⁻ + H⁺

Mg(OH)₂ = Mg²⁺ + 2OH⁻

Answer 2

Answer:
`Mg(OH)_2\rightarrow  Mg^(2+)+2OH^–`

Step-by-step explanation:

Ionization is a type of chemical reaction in which one reactant gives ions on decomposition.

`A\rightarrow B^++C^-`

1.
`C+O_2\rightarrow CO_2` is an example of is an example of synthesis reaction in which two reactants are combining to form one product.

2.
`H_2CO_3\rightarrow H_2O+CO_2` is an example decomposition is a type of chemical reaction in which one reactant gives two or more than two products.

3.
`SO_2+H_2O\rightarrow HSO_3^-+H^+` : 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.
`Mg(OH)_2\rightarrow  Mg^(2+)+2OH^–` is an example of ionization in which one reactant gives ions on decomposition.
